programmable block lcd panel write text brands

The LCD Panel is a thin panel that takes an entire block face and can display a variety of messages and textures that can be displayed constantly or triggered by the Programmable Block, Sensor, Timer Block, or any other block capable of triggering.

Choosing "Edit Text" allows inputting custom text such as the name of a room to use above doors. The text can then be scaled up to fit the screen dimensions or preferred size by using the "Font Size" slider.

The "Color" sliders allow setting the text colour using RGB slider and "Backgr." allows setting background fill colours (default black). If using a transparent LCD then the text will be against transparency unless fill colour is added.

"Loaded Textures" has a list of the available default and modded (where applicable) images available for display on the screen. Select the desired image and select "Add to selection". The selected image will then show in the second "Selected textures" panel.

When multiple images are applied they can be set to cycle between with the duration between images being set by the "Image change interval" slider. To remove an image from display select it in the second panel and select "Remove selected".

The "Preserve aspect ratio" checkbox can be used to prevent the image being stretched if it does not fit the screen properly such as when using a wide LCD.

To set the LCD to display a script, choose "Script" from the dropdown. Choosing Script allows the display of information such as weather, artificial horizon for vehicles, Energy and Hydrogen level etc.

The panel"s title and text can be made public, private, or a combination of both. Textures applied can be selected from a list or custom textures can be selected. Textures can be set to rotate on a timer, changing from one to the next. GPS coordinates shown in the GPS format in the text panel will appear in the GPS and can be activated (=shown on HUD).

Selected textures - Any textures that were added, will be displayed here. The order in which they are placed effects which image is displayed first (top of the list is displayed first).

The LCD Panel could be accessed with the programmable block as IMyTextPanel. It could work in ´Texture Mode´ in which the selected textures are shown or the ´Text Mode´ in which the text is shown. The following methods are available:

Adds an image/texture to the end of the list of selected textures. If no image/texture with the name id exists the texture ´Offline´ is added instead.

Adds the images/textures to the end of the list of selected textures. If no image/texture with the name id exists the texture ´Offline´ is added instead.

If you plan on using an LCD with your Raspberry Pi, there’s a good chance you’ll need to program it in Python at some point. Python is probably the most popular programming language for coding on the Raspberry Pi, and many of the projects and examples you’ll find are written in Python.

In this tutorial, I’ll show you how to connect your LCD and program it in Python, using the RPLCD library. I’ll start with showing you how to connect it in either 8 bit mode or 4 bit mode. Then I’ll explain how to install the library, and provide examples for printing and positioning text, clearing the screen, and controlling the cursor. I’ll also give you examples for scrolling text, creating custom characters, printing data from a sensor, and displaying the date, time, and IP address of your Pi.

You can also connect the LCD via I2C, which uses only two wires, but it requires some extra hardware. Check out our article, How to Setup an I2C LCD on the Raspberry Pi to see how.

There are two ways to connect the LCD to your Raspberry Pi – in 4 bit mode or 8 bit mode. 4 bit mode uses 6 GPIO pins, while 8 bit mode uses 10. Since it uses up less pins, 4 bit mode is the most common method, but I’ll explain how to set up and program the LCD both ways.

Each character and command is sent to the LCD as a byte (8 bits) of data. In 8 bit mode, the byte is sent all at once through 8 data wires, one bit per wire. In 4 bit mode, the byte is split into two sets of 4 bits – the upper bits and lower bits, which are sent one after the other over 4 data wires.

Theoretically, 8 bit mode transfers data about twice as fast as 4 bit mode, since the entire byte is sent all at once. However, the LCD driver takes a relatively long time to process the data, so no matter which mode is being used, we don’t really notice a difference in data transfer speed between 8 bit and 4 bit modes.

If this is your first time writing and running a Python program, you might want to read How to Write and Run a Python Program on the Raspberry Pi, which will explain everything you need to know to run the examples below.

The RPLCD library can be installed from the Python Package Index, or PIP. It might already be installed on your Pi, but if not, enter this at the command prompt to install it:

The example programs below use the Raspberry Pi’s physical pin numbers, not the BCM or GPIO numbers. I’m assuming you have your LCD connected the way it is in the diagrams above, but I’ll show you how to change the pin connections if you need to.

Let’s start with a simple program that will display “Hello world!” on the LCD. If you have a different sized LCD than the 16×2 I’m using (like a 20×4), change the number of columns and rows in line 2 of the code. cols= sets the number of columns, and rows= sets the number of rows. You can also change the pins used for the LCD’s RS, E, and data pins. The data pins are set as pins_data=[D0, D1, D2, D3, D4, D5, D6, D7].

The text can be positioned anywhere on the screen using lcd.cursor_pos = (ROW, COLUMN). The rows are numbered starting from zero, so the top row is row 0, and the bottom row is row 1. Similarly, the columns are numbered starting at zero, so for a 16×2 LCD the columns are numbered 0 to 15. For example, the code below places “Hello world!” starting at the bottom row, fourth column:

The RPLCD library provides several functions for controlling the cursor. You can have a block cursor, an underline cursor, or a blinking cursor. Use the following functions to set the cursor:

Text will automatically wrap to the next line if the length of the text is greater than the column length of your LCD. You can also control where the text string breaks to the next line by inserting \n\r where you want the break to occur. The code below will print “Hello” to the top row, and “world!” to the bottom row.

This program will print the IP address of your ethernet connection to the LCD. To print the IP of your WiFi connection, just change eth0 in line 19 to wlan0:

Each character on the LCD is an array of 5×8 of pixels. You can create any pattern or character you can think of, and display it on the screen as a custom character. Check out this website for an interactive tool that creates the bit array used to define custom characters.

First we define the character in lines 4 to 12 of the code below. Then we use the function lcd.create_char(0-7, NAME) to store the character in the LCD’s CGRAM memory. Up to 8 (0-7) characters can be stored at a time. To print the custom character, we use lcd.write_string(unichr(0)), where the number in unichr() is the memory location (0-7) defined in lcd.create_char().

In general, you take the input variable from your sensor and convert it to an integer to perform any calculations. Then convert the result to a string, and output the string to the display using lcd.write_string(sensor_data()):

Well, that about covers most of what you’ll need to get started programming your LCD with Python. Try combining the programs to get some interesting effects. You can display data from multiple sensors by printing and clearing the screen or positioning the text. You can also make fun animations by scrolling custom characters.

There are fourteen new decorative blocks for people who want to buy them and support the development of Space Engineers, which are available on the Space Engineers Steam Store page. Within the package you will get following new blocks:

Beds can preserve characters’ inventory and toolbar while they"re offline and keeps them alive as long as there is oxygen available. Is considered to be the same as the Cryo Chamber Block, except oxygen is used from the environment. Space Engineers don’t work from nine to five, they work whenever they’re needed: day or night, during peace and war. But when it’s time to call it a day, every engineer looks forward to resting in these beds.

Standard and Corner Desks can be used as seats, which allow players to sit on the chair attached to it. Combine these blocks to produce various designs and sizes, creativity has no limitation. Whether designing new schematics or charting a fresh course to another world, desks are essential for any engineer looking to get some work done.

Console blocks project blueprints for downscaled ships and stations, as well as display pictograms or customizable text. They are fantastic functional LCD panels where you can project your creations and show them to your friends. The sleek and crystal clear picture offered by this console allows Space Engineers to display designs and other important information.

*Note to modders: When modding the decorative blocks, copy the current settings and then do the change on top of that. The mod will also include the DLC tag:

Why are they high-risk? Because they are hard to do, and usually it takes many iterations until we figure out the right way to do it. It usually takes a few iterations to perfect it. This means that doing water can take a few weeks (if we get it right from the start) or a few years (if we need to experiment, iterate, throw away past experiments, look for specialists in this area, etc). Same for the engine rewrite and AI / living worlds for our games.

A:Actually, even this update isn’t paid. The major part of this update (LCD screens, Replay Tool, new music tracks, smaller improvements) is free for everyone. Only the smaller and not mandatory part is paid - Decorative Pack, which you can purchase here.

A: The way we designed this is that even people who don’t purchase the Decorative Pack can play on servers with people who own the Decorative Pack. Players who don’t own the Decorative Pack won’t be able to build with these new blocks, nor interact with them, but they will be able to view them in-game.

A: Hehe, if you put it this way, it sounds kind of funny. But the reality is that decorative blocks are low-hanging fruit, not a bottleneck towards those other mentioned future features. Additionally, the decorative pack can bring added profit and make the mentioned things happen.

As one of the IEC-61131PLC programming languages, Structured Text or just ST is based on and resembles traditional programming languages like Python or Java.

Like all programming languages, Structured Text has advantages and disadvantages, and there are also reasons you as a programmer might choose to use Structured Text in your next PLC programming project, so let’s get right into it.

Since Structured Text is similar to traditional High-Level programming languages, it can be fairly easy for many people who may not have a background in PLC programming but have experience in traditional coding to learn and develop PLC projects.

In most cases, you can also develop your Structured Text PLC programming project without using the PLC programming software. Since it is text-based, you can write your project in a simple text file and copy and paste it into your PLC project when you are ready.

This also makes editing your project easier when you are debugging. While this feature of Structured Text is useful, remember that withoutyour programming software like TIA Portal or RSLogix, you cannot compile and debug your program.

Since Structured Text is by definition, text-based, it means that it does not have the memory-intensive graphical interface which can allow for a smaller processor memory and therefore a reduced cost.

Some other times you might want to use Structured Textare when you are deploying the same PLC program over and over, such as in a packaged machine that is sent to a customer for a turn-key start-up.

In these cases, your PLC program file can be stored offline in a text file or word document and can be easily sent as an email attachment for someone to download into the PLC and deploy.

– Also, Structured Text is not case sensitive, but if you are assigning a variable, known as a tag or a symbol such as control valve 1, then using camelCase ControlValve1 is a good practice to get into.

Another very common and useful syntax of Structured Text is the use of a comment. As a beginning programmer, the use of comments is essential to creating code that can be read later on.

As you can see, to add a comment in Structured Text you will start with a left parenthesis followed by an asterisk. To close your comment, you will then add another asterisk followed by a right parenthesis.

Structured Text also uses operators to manipulate data. Some examples of operators are the logical operators such as AND, OR, and NOT.A logical operator is used to compare Boolean data and create logic from it.

Congratulations! You have just created your first routine in Structured Text! How cool is that? While this simple tutorial was an introduction to Structured Text, adding the ability to utilize Structured Text in your projects will be another powerful tool in your programmer’s toolbox.

If you have any questions about the Structured Text, or about programming languages in general, add them in the comments below and we will get back to you in less than 24 hours.

The function of a terminal is typically confined to transcription and input of data; a device with significant local, programmable data-processing capability may be called a "smart terminal" or fat client. A terminal that depends on the host computer for its processing power is called a "dumb terminal"thin client.terminal emulator software that replicates functions of a real-world terminal, sometimes allowing concurrent use of local programs and access to a distant terminal host system, either over a direct serial connection or over a network using, e.g., SSH.

In 1955, the Whirlwind Mark I computer was the firstFriden Flexowriter, which would continue to serve this purpose on many other early computers well into the 1960s.

Early user terminals connected to computers were, like the Flexowriter, electromechanical teleprinters/teletypewriters (TeleTYpewriter, TTY), such as the Teletype Model 33, originally used for telegraphy; early Teletypes were typically configured as Keyboard Send-Receive (KSR) or Automatic Send-Receive (ASR), the latter including a paper tape reader and punch. This led to the use of the current loop interface that was already used in telegraphy, as well as a thriving market in surplus machines for computer use.

The DECwriter was the last major printing-terminal product. It faded away after 1980 under pressure from video display units (VDUs), with the last revision (the DECwriter IV of 1982) abandoning the classic teletypewriter form for one more resembling a desktop printer.

A video display unit (VDU) displays information on a screen rather than printing text to paper and typically uses a cathode-ray tube (CRT). Due to that technology these devices were often called "CRTs". VDUs in the 1950s were typically designed for displaying graphical data rather than just text. CRT displays in that time frame were used in, e.g., experimental computers at MIT; Commercial computer from, e.g., DEC, ERA, IBM, UNIVAC; military computers for, e.g., BMEWS, BUIC, SAGE.

Two early landmarks in the development of the VDU were the Univac Uniscope 300IBM 2260, both in 1964. Both were block-mode terminals designed to ship a page at a time, rather than character-mode devices. The Hazeltine 2000 of 1970 was a notable later product of the same kind.

24 lines (or possibly 25 – sometimes a special status line) of 72 or 80 characters of text (80 was the same as IBM punched cards). Later models sometimes had two character-width settings.

Although flat-panel displays were available since the 1950s, cathode-ray tubes continued to dominate the market until the personal computer had made serious inroads into the display terminal market. By the time cathode-ray tubes on PCs were replaced by flatscreens after the year 2000, the hardware computer terminal was nearly obsolete.

Some dumb terminals had been able to respond to a few escape sequences without needing microprocessors: they used multiple printed circuit boards with many integrated circuits; the single factor that classed a terminal as "intelligent" was its ability to process user-input within the terminal—not interrupting the main computer at each keystroke—and send a block of data at a time (for example: when the user has finished a whole field or form). Most terminals in the early 1980s, such as ADM-3A, TVI912, Data General D2, DEC VT52, despite the introduction of ANSI terminals in 1978, were essentially "dumb" terminals, although some of them (such as the later ADM and TVI models) did have a primitive block-send capability. Common early uses of local processing power included features that had little to do with off-loading data processing from the host computer but added useful features such as printing to a local printer, buffered serial data transmission and serial handshaking (to accommodate higher serial transfer speeds), and more sophisticated character attributes for the display, as well as the ability to switch emulation modes to mimic competitor"s models, that became increasingly important selling features during the 1980s especially, when buyers could mix and match different suppliers" equipment to a greater extent than before.

The ANSI X3.64 escape code standard produced uniformity to some extent, but significant differences remained. For example, the VT100, Heathkit H19 in ANSI mode, Televideo 970, Data General D460, and Qume QVT-108 terminals all followed the ANSI standard, yet differences might exist in codes from function keys, what character attributes were available, block-sending of fields within forms, "foreign" character facilities, and handling of printers connected to the back of the screen.

When using a graphical user interface (or GUI) like the X Window System, one"s display is typically occupied by a collection of windows associated with various applications, rather than a single stream of text associated with a single process. In this case, one may use a terminal emulator application within the windowing environment. This arrangement permits terminal-like interaction with the computer (for running a command-line interpreter, for example) without the need for a physical terminal device; it can even run multiple terminal emulators on the same device.

A character-oriented terminal is a type of computer terminal that communicates with its host one character at a time, as opposed to a block-oriented terminal that communicates in blocks of data. It is the most common type of data terminal, because it"s easy to implement and program. Connection to the mainframe computer or terminal server is achieved via RS-232 serial links, Ethernet or other proprietary protocols.

A text terminal, or often just terminal (sometimes text console) is a serial computer interface for text entry and display. Information is presented as an array of pre-selected formed characters. When such devices use a video display such as a cathode-ray tube, they are called a "video display unit" or "visual display unit" (VDU) or "video display terminal" (VDT).

The fundamental type of application running on a text terminal is a command-line interpreter or prompts for commands from the user and executes each command after a press of Return.Unix shells and some interactive programming environments. In a shell, most of the commands are small applications themselves.

Another important application type is that of the text editor. A text editor typically occupies the full area of display, displays one or more text documents, and allows the user to edit the documents. The text editor has, for many uses, been replaced by the word processor, which usually provides rich formatting features that the text editor lacks. The first word processors used text to communicate the structure of the document, but later word processors operate in a graphical environment and provide a WYSIWYG simulation of the formatted output. However, text editors are still used for documents containing markup such as DocBook or LaTeX.

In the simplest form, a text terminal is like a file. Writing to the file displays the text and reading from the file produces what the user enters. In Unix-like operating systems, there are several character special files that correspond to available text terminals. For other operations, there are special escape sequences, control characters and termios functions that a program can use, most easily via a library such as Unix systems typically buffer the input text until the Enter key is pressed, so the application receives a ready string of text. In this mode, the application need not know much about the terminal. For many interactive applications this is not sufficient. One of the common enhancements is command-line editing (assisted with such libraries as readline); it also may give access to command history. This is very helpful for various interactive command-line interpreters.

Even more advanced interactivity is provided with full-screen applications. Those applications completely control the screen layout; also they respond to key-pressing immediately. This mode is very useful for text editors, file managers and web browsers. In addition, such programs control the color and brightness of text on the screen, and decorate it with underline, blinking and special characters (e.g. box-drawing characters). To achieve all this, the application must deal not only with plain text strings, but also with control characters and escape sequences, which allow moving the cursor to an arbitrary position, clearing portions of the screen, changing colors and displaying special characters, and also responding to function keys. The great problem here is that there are many different terminals and terminal emulators, each with its own set of escape sequences. In order to overcome this, special libraries (such as curses) have been created, together with terminal description databases, such as Termcap and Terminfo.

Practically all modern graphic displays are raster-mode, descended from the picture scanning techniques used for television, in which the visual elements are a rectangular array of pixels. Since the raster image is only perceptible to the human eye as a whole for a very short time, the raster must be refreshed many times per second to give the appearance of a persistent display. The electronic demands of refreshing display memory meant that graphic terminals were developed much later than text terminals, and initially cost much more.

A terminal emulator is a piece of software that emulates a text terminal. In the past, before the widespread use of local area networks and broadband internet access, many computers would use a serial access program to communicate with other computers via telephone line or serial device.

Block mode (a.k.a. screen-at-a-time mode): In this mode (also called block-oriented), the terminal is buffered and provides a local full-screen data function. The user can enter input into multiple fields in a form on the screen (defined to the terminal by the receiving system), moving the cursor around the screen using keys such as Tab ↹ and the arrow keys and performing editing functions locally using insert, delete, ← Backspace and so forth. The terminal sends only the completed form, consisting of all the data entered on the screen, to the receiving system when the user presses an ↵ Enter key.

There is a distinction between the return and the ↵ Enter keys. In some multiple-mode terminals, that can switch between modes, pressing the ↵ Enter key when not in block mode does not do the same thing as pressing the return key. Whilst the return key will cause an input line to be sent to the host in line-at-a-time mode, the ↵ Enter key will rather cause the terminal to transmit the contents of the character row where the cursor is currently positioned to the host, host-issued prompts and all.↵ Enter and local cursor moving keys such as Return and New Line.

Different computer operating systems require different degrees of mode support when terminals are used as computer terminals. The POSIX terminal interface, as provided by Unix and POSIX-compliant operating systems, does not accommodate block-mode terminals at all, and only rarely requires the terminal itself to be in line-at-a-time mode, since the operating system is required to provide canonical input mode, where the terminal device driver in the operating system emulates local echo in the terminal, and performs line editing functions at the host end. Most usually, and especially so that the host system can support non-canonical input mode, terminals for POSIX-compliant systems are always in character-at-a-time mode. In contrast, IBM 3270 terminals connected to MVS systems are always required to be in block mode.

A block-oriented terminal or block mode terminal is a type of computer terminal that communicates with its host in blocks of data, as opposed to a character-oriented terminal that communicates with its host one character at a time. A block oriented terminal may be card-oriented, display oriented, keyboard-display, keyboard-printer, printer or some combination.

Block-oriented terminals typically incorporate a buffer which stores one screen or more of data, and also stores data attributes, not only indicating appearance (color, brightness, blinking, etc.) but also marking the data as being enterable by the terminal operator vs. protected against entry, as allowing the entry of only numeric information vs. allowing any characters, etc. In a typical application the host sends the terminal a preformatted panel containing both static data and fields into which data may be entered. The terminal operator keys data, such as updates in a database entry, into the appropriate fields. When entry is complete (or ENTER or PF key pressed on 3270s), a block of data, usually just the data entered by the operator (modified data), is sent to the host in one transmission. The 3270 terminal buffer (at the device) could be updated on a single character basis, if necessary, because of the existence of a "set buffer address order" (SBA), that usually preceded any data to be written/overwritten within the buffer. A complete buffer could also be read or replaced using the READ BUFFER command or WRITE command (unformatted or formatted in the case of the 3270).

Block-oriented terminals cause less system load on the host and less network traffic than character-oriented terminals. They also appear more responsive to the user, especially over slow connections, since editing within a field is done locally rather than depending on echoing from the host system.

Programmers of block-oriented terminals often used the technique of storing context information for the transaction in progress on the screen, possibly in a hidden field, rather than depending on a running program to keep track of status. This was the precursor of the HTML technique of storing context in the URL as data to be passed as arguments to a CGI program.

Unlike a character-oriented terminal, where typing a character into the last position of the screen usually causes the terminal to scroll down one line, entering data into the last screen position on a block-oriented terminal usually causes the cursor to wrap— move to the start of the first enterable field. Programmers might "protect" the last screen position to prevent inadvertent wrap. Likewise a protected field following an enterable field might lock the keyboard and sound an audible alarm if the operator attempted to enter more data into the field than allowed.

The Application Program Interface (API) libraries associated with the language: You don’t want to write everything from scratch yourself. Instead, you can re-use the available code in the library. Learning library could be difficult as it is really huge, evolving and could take on its own life as another programming language.

Step 1: Write the source code Xxx.java using a programming text editor (such as Sublime Text, Atom, Notepad++, Textpad, gEdit) or an IDE (such as Eclipse or NetBeans).

You can use the following template to write your Java programs. Choose a meaningful "Classname" that reflects the purpose of your program, and write your programming statements inside the body of the main() method. Don"t worry about the other terms and keywords now. I will explain them in due course. Provide comments in your program!

Block: A block is a group of programming statements surrounded by a pair of curly braces { }. All the statements inside the block is treated as one single unit. Blocks are used as the body in constructs like class, method, if-else and loop, which may contain multiple statements but are treated as one unit (one body). There is no need to put a semi-colon after the closing brace to end a compound statement. Empty block (i.e., no statement inside the braces) is permitted.

Indentation: Indent each level of the body of a block by an extra 3 or 4 spaces according to the hierarchy of the block. Don"t use tab because tab-spaces is editor-dependent.

The following diagram illustrates three types of variables: int, double and String. An int variable stores an integer (or whole number or fixed-point number); a double variable stores a floating-point number (or real number); a String variable stores texts.

A variable is declared with a type. Once the type of a variable is declared, it can only store a value belonging to that particular type. For example, an int variable can hold only integer (such as 123), and NOT floating-point number (such as -2.17) or text string (such as "Hello").

Beside the 8 primitive types, another important and frequently-used type is String. A String is a sequence of characters (texts) such as "Hello, world". String is not a primitive type (this will be elaborated later).

As a programmer, YOU need to decide on the type of the variables to be used in your programs. Most of the times, the decision is intuitive. For example, use an integer type for counting and whole number; a floating-point type for number with fractional part, String for text message, char for a single character, and boolean for binary outcomes.

You are required to identify the variables, assign a suitable name to each variable and choose an appropriate type. Write the variable declaration statements as in the above example.

Exercise: Write a program to print the following animal picture using System.out.println(). Take note that you need to use escape sequences to print some characters, e.g., \" for ", \\ for \.

Newline (0AH) and Carriage-Return (0DH), represented by the escape sequence \n, and \r respectively, are used as line delimiter (or end-of-line, or EOL) for text files. Take note that Unix and macOS use \n (0AH) as EOL, while Windows use \r\n (0D0AH).

Java does not have an exponent operator. (The ^ operator denotes exclusive-or, NOT exponent). You need to use JDK method Math.exp(x, y) to evaluate x raises to power y; or write your own code.

Take note that the comparison operators are binary infix operators, that operate on two operands with the operator in between the operands, e.g., x <= 100. It is invalid to write 1 < x < 100 (non-binary operations). Instead, you need to break out the two binary comparison operations x > 1, x < 100, and join with a logical AND operator, i.e., (x > 1) && (x < 100), where && denotes AND operator.

Exercise: Given the year, month (1-12), and day (1-31), write a boolean expression which returns true for dates before October 15, 1582 (Gregorian calendar cut-over date).

Take note that the blocks are exclusive in a nested-if statement; only one of the blocks will be executed. Also, there are two ways of writing nested-if, for example,

Formatting-string contains both normal texts and the so-called Format Specifiers. Normal texts (including white spaces) will be printed as they are. Format specifiers, in the form of "%[flags][width]conversionCode", will be substituted by the arguments following the formattingString, usually in a one-to-one and sequential manner. A format specifier begins with a "%" and ends with the conversionCode, e.g., %d for integer, %f for floating-point number (float and double), %c for char and %s for String. An optional width can be inserted in between to specify the field-width. Similarly, an optional flags can be used to control the alignment, padding and others. For examples,

Write a program called IncomeTaxCalculator that reads the taxable income (in int). The program shall calculate the income tax payable (in double); and print the result rounded to 2 decimal places.

Based on the previous example, write a program called IncomeTaxCalculatorSentinel which shall repeat the calculations until user enter -1. For example,

It is important to write programs that produce the correct results. It is also important to write programs that others (and you yourself three days later) can understand, so that the programs can be maintained. I call these programs good programs - a good program is more than a correct program.

Let"s rewrite the above program to list all the primes instead. A boolean flag called isPrime is used to indicate whether the current number is a prime. It is then used to control the printing.

Let"s rewrite the above program without using break statement. A while loop is used (which is controlled by the boolean flag) instead of for loop with break.

There are 3 cases to handle: "1" (add to dec), "0" (valid but do nothing for multiply by 0) and other (error). We can write the nested-if as follows, but that is harder to read:

Example: Suppose that we need to evaluate the area of a circle many times, it is better to write a method called getArea(), and re-use it when needed.

Suppose you need a method to compute the sum of the elements for int[], short[], float[] and double[], you need to write all overloaded versions - there is no shortcut.

An algorithm is a step-by-step instruction to accomplice a task, which may involve decision and iteration. It is often expressed in English-like pseudocode, before translating into programming statement of a particular programming language. There is no standard on how to write pseudocode - simply write something that you, as well as other people, can understand the steps involved, and able to translate into a working program.

LCD Panel blocks have only one built-in LCD Surface, but other functional blocks have several LCD surfaces built in, for example Cockpits, Programmable Blocks, Custom Turret Controllers, Button Panels, and so on. All LCD surfaces work the same way, and have the same settings as the freestanding LCD Panel blocks. In constrast to the block variants, built-in LCD surfaces are fixed to their block "as is" and you cannot choose different screen sizes or positions. The advantage of the built-in surfaces is that they do not take up extra block space.

Tip: If you are looking for an option to display inventory capacity, radar view, planetary maps, hull integrity, and the like, alas these scripts are not available by default. To calculate and display such information, you need a Programmable Block. Advanced players can write custom scripts, and everyone can download community-provided scripts from the Workshop that can be configured to output info from the Programmable Block to an LCD of your choice.

Edit Text -- Click this button to enter or paste text to display. Lines don"t wrap automatically, so enter line breaks where necessary to make it fit.

Loaded Textures -- Select from the list of default images, then click Add to Selection to display it. You can add more than one image and cycle, but you can only see one at a time.

You can configure text settings, or image settings, or both. If you provide both text and image, it will display the text on top of the image, which adds nice flexibility to create your own combinations of icons and custom messages.

Note: If you select the texture named "Faction" here, you"ll get a generic static "Red Fist" logo, not your own faction logo. To get your faction logo, you want the "Faction icon" script instead.

Second, consider creating your custom image out of Monospace text, using Block Elements as pixels. Here is a great community app that converts any pictures into Block Element text: https://github.com/Whiplash141/Whips-Image-Converter/

Some scripts even display barcharts for the fill levels of cargo, remaining fuel, ship damage status, etc. dynamically, simply by printing sequences of Block Elements or text characters to the screen once per second, to fake portable "graphics" cheaply.
