lcd module commands pricelist

This serial LCD kit includes a 16x2 LCD together with a small "serial interface" PCB fitted with a PICAXE-18M2 chip. The on-board PICAXE-18M2 chip is provided pre-programmed with the open-source AXE133 firmware, which allows this on-board 18M2 chip to act as a "slave" serial driver for the LCD display. This allows your main project to display text on the serial LCD via simple serout commands, such as

The control codes are identical to our popular AXE033 module, so this kit can be used as an altenate to the AXE033. On this board the slave chip is a completely normal 18M2, so it can also be reprogrammed whenever you want (e.g. to change the power-up welcome message or even temporarily "borrowed" for another project!). Click on the resources tab above to download the AXE133 BASIC firmware file.

As announced in a PCN 10286 https://www.crystalfontz.com/news/pcn.php?id=10286 on 2010/10/06, the new CFA633 hardware v2.0 / Firmware version 2.0 ("s2.0" for serial modules and "u2.0" for USB modules) is fit, form, and function compatible with previous versions of the CFA633 series (hardware versions 1.5x).

In command 5 (0x05): Reboot CFA633, Reset Host, or Power Off Host, the module now knows if it is coming from a power up or from a reset. This in turn improves the bootup sequence. A note was added to describe the brief delay at bootup when more than one of the optional fans are on.

In command 12 (0x0C): Set LCD Cursor Style, cursor style choice "3" changed from "3 = blinking block plus underscore" to "3 = blinking underscore cursor." The rate at which the cursor blinks is faster than in previous CFA633 versions (HW v1.x).

For information on additional changes, please see the Data Sheet’s Revision History. For a technical bulletin comparing CFA633 modules by version number, see PCN 10291 at https://www.crystalfontz.com/news/pcn.php?id=10291 published 2010/11/10.

The attached PDF file describes differences between our CFA633 v1.5x and CFA633 v2.0 intelligent display module series. We also list the CFA533 series as a comparison for customers who do not require the fan control available in the CFA633 series. Hardware version numbers are silk screened on the back of the PCBs.

Wanna add an interface to your project? Use the 16x2 standard alphanumeric LCD display, they are extremely common and is a fast way to have your project show status messages.

An LCD (Liquid Crystal Display) screen is an electronic display module and has a wide range of applications. A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits. A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each character is displayed in 5x7 pixel matrix. The 16 x 2 intelligent alphanumeric dot matrix display is capable of displaying 224 different characters and symbols.

This LCD has two registers, namely, Command and Data.Command register stores various commands given to the display. Data register stores data to be displayed. The process of controlling the display involves putting the data that form the image of what you want to display into the data registers, then putting instructions in the instruction register. In your arduino project Liquid Crystal Library simplifies this for you so you don"t need to know the low-level instructions.

Character Liquid Crystal Displays (LCDs) are a fantastic addition to many electronics projects. These handy devices allow programmers to display status and debug messages for easier bug fixing, and they give users of a project a more intuitive way to interact with the device. There’s a good chance that you’ve already used a library that allows you to effortlessly incorporate such a display into one of your Arduino or Raspberry Pi projects!

Looking at the underlying communication protocol implemented by these libraries uncovers a few exciting possibilities. Furthermore, understanding the nitty-gritty details of these displays allows you to utilize simple character LCDs in many new projects, even without adding an Arduino or a similar MCU development board. This article investigates the most commonly used communication protocol of a standard 16x2 character LCD and how you can use it in your projects.

Since its introduction in the 1980s, the HD44780 controller has become a de-facto standard for communicating with LCDs. Therefore, almost all character LCDs share the same 14 to 16 pins that you need to connect to utilize such a display in your project. You can find a detailed description of how to interface LCDs using an Arduino in this article.

For now, focus on the RS (register select), EN (enable), and the eight data pins (D7 through D0) of the LCD. Note that there is also an RW (read/write) for selecting the direction of an operation. However, it doesn’t make sense to read data from the display in many cases. Therefore, this pin is often tied to GND to permanently make the display operate in write mode (for transmitting data from a controller to the LCD).

In the table above, the lower-case x means that the bit in this position can be set to any value. Additionally, you can see that some commands take parameters that change their behavior. For example, the I/D bit indicates whether the controller should increment or decrement the cursor position. When the S bit of the same command is set, the controller shifts the display contents. Next, the D, C, and B bits control whether certain display functions are on or off. For example, using the D bit, you can turn off the entire display, the C bit lets you enable or disable the cursor, and B activates or deactivates the cursor blink. Similarly, S/C and R/L let you shift or move the display contents (S/C) in a specific direction (R/L). Lastly, the DL, N, and F bits allow you to set the display to operate in either 4-bit or 8-bit mode (DL), specify the number of display lines (N), and select the font (F).

Communicating with a standard 16x2 character LCD is not as difficult as it might seem at first. Each command that the HD44780 controller accepts consists of eight data bits. The standard HD44780 supports two communication modes. In eight-bit mode, the MCU that wants to display data needs to send all eight bits at once while keeping the RS and RW lines stable. The MCU can instruct the controller to latch all eight data bits using the EN line. However, the MCU needs to transmit the eight data bits using two half-bytes in four-bit mode. Similar to the eight-bit mode, the RS and RW lines must remain stable during the entire transmission. However, in four-bit mode, the MCU needs to send two EN pulses that signal the HD44780 to latch each of the four data bits.

The HD44780 contains two registers, and the MCU can select which one it wants to access using the RS bit. Setting this bit low selects the LCD controller’s command register, and pulling the pin high allows the MCU to access the HD44780’s data register. The controller supports eleven commands that may or may not allow the MCU to supply additional parameters by setting various bits.

A 2.4” TFT LCD module consists of a bright backlight (4 white LEDs) and a colourful 240X320 pixels display. It also features individual RGB pixel control giving a much better resolution than the black and white displays. A resistive touch screen comes pre-installed with the module as a bonus and hence you can easily detect your finger presses anywhere on the screen.

The TFT comes with an auto-reset circuit which gets active on every breakout. However, a user can reset the module using this pin also, in case setup is not resetting clean.

Resistive Touch Pins – Y+, X+, Y-, and X- are the 4 resistive touch pins which require analog pins to read and determine touch pins. Their overlay is fixed at the top of the module which makes them electrically separate from the TFT. They can be used is 8-bit as well as SPI mode.

The 2.4” TFT LCD module supports many modes. However, two of them are very popular among users – “SPI mode” and “8-bit mode”. The display contains pins on both sides required for a mode and a user can switch easily between them by simply rewiring the display. It should be noted that only one mode can be used at a time.

A 2.4” TFT module has a very flexible usage. It is compatible with all your DIY projects where you want to add a bright, colourful, and touchscreen enabled display.
