tft lcd interface with microcontroller quotation

The display is a critical component in every project, impacting the case, firmware, electrical design, user interface, and even battery life. For these reasons, and because it is the most visible component of your product, it must be approved by the mechanical design team, management and marketing.Before these teams can approve, they need to see it in action. But it can take days or weeks to connect a display to your platform, initialize it and build a code library able to create believable demonstrations. Meanwhile, the whole project is on hold.Our 8051 development kit / demonstration board can solve this problem. Use it to get the display seen, demonstrated and approved for your project.

The datasheet of the LCD tells you the signals that must be present on the LCD interface pins. How you achive that is up to you, you can bit-bang the signals on GPIOs, use an-on chip or off-chip LCD controller, a custom-programmed FPGA, or even black magic. The LCD doen"t care.

In most cases, the 8/16 bit interfaces (and for smaller LCDs, SPI or I2C interfaces) talk to some kind of controller on the LCD. The communication is in terms of instructions, like "set these pixels to black". This kind of interface can easily be done by the CPU (using bit-banging)

In most cases, interfaces that mention RGB line and SYNC signals interface more directly to the LCD: they specify the full data that must be displayed, and this data (a frame) must be repeated at the frame rate (typically 10..100 Hz). This requires much more attention from the CPU if it would do it all by its own, and for larger LCDs this is totally impractical. (Where the switchover point lies depends on the CPU, programmer skills,a nd CPU time needed for the rest of the application.) These type of LCDs are generally interfaced via an on-chip LCD controller.

Since the display includes the Ilitek ILI9320 controller, then your interface requirements are much lower, as the microcontroller no longer has to interface directly with the TFT and instead only talks to the controller chip via a simple interface: either SPI, which takes six wires: RS, CS, CLK, MOSI, MISO and RESET. Or you can use an 8080-compatible parallel interface which takes 13 wires: an 8-bit data bus, and RS, CS, WR, RD and RESET. (There are options to use larger data-buses, up to 18 bits, but I don"t recommend that for a low end microcontroller.)

There are two optional interfaces in which the microcontroller generates all of the clock signals (VSYNC, HSYNC and DOTCLK); you don"t want to do that since it would require a high-end controller.

So just about any microcontroller will do, however you need to have enough flash memory to hold whatever static items you want to display; for example if you are going to be displaying text then you will need to allocate arrays to store bitmaps for whatever fonts you will use. Even a small font can take 60KB.

This graphic display module is a 2.4" diagonal, full color TFT. Suitable for embedded applications, it is low-power, uses a white LED backlight, and has an integrated touch panel which has its connection brought out to the main TAB connector for the display.

It has an on-board controller and 3v single voltage for supply and logic (backlight not included), so you can easily use any modern microcontroller to interface with this display. It uses an 8 or 16 bit parallel interface, specified via connections to the display.

The connector on the CFAF240320K-024T-TS is a flex tail mated with a "COG" (chip on glass) display construction.

High volume contract manufacturers will be familiar with this type of construction and its assembly methods. There are hot-bar soldering machines made that are designed for prototype, rework or repair work of TAB connections.

J-Link Product PageSEGGER J-Links are the most widely used line of debug probes available today. They’ve been proven for more than 10 years with over 250,000 units sold, including OEM versions and on-board solutions. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.

Displays have over time, emerged as one of the best ways to drive user interactions on any device. They make it easy to collect inputs and present information (outputs) to users in a graphical, easy to understand format. This usefulness has led to improvements in their quality, with improved resolution and low power features, but almost little has changed when it comes to the complexity of creating beautiful user interfaces for them. This is why the team at STONE Tech created the STVC035WT-01 intelligent Smart display which we will explore for today’s tutorial.

The STONE STVC035WT-01 display is a 16-bit, 3.5″ display with a 320×480 (RGB) resolution, has a 49.0 x 73.4mm viewing area, and pixel spacing of 0.1905mm×0.0635mm (H×V). The display is a Class A industry Panel with an Industry level 4 wire resistance based touch screen, all layered on an integrated CPU, driver, and flash memory with several communication interfaces to enable it to connect to data sources like microcontrollers. For communication with a microcontroller, the display supports serial communication protocols likeUART/TTL, RS232, and RS485, ensuring it can communicate with any kind of microcontroller or industrial computers. The UART/TTL pin on the Display supports both 3.3v/5v logic level which adds another layer of ease to the use of the display as users need not worry about the need for logic level shifters when building using a microcontroller that operates on either of the voltage level mentioned.

One of the major benefits of using this display is its compatibility with the STONE TOOL GUI Designer which allows the development of User Interfaces in a fast and easy manner.

To demonstrate the capabilities of the display, we will build a heart rate monitor using an Arduino Uno with the MAX30100 pulse oximetry and heart rate sensor. The Arduino will serve as the brain of the project and perform the simple task of obtaining the heart rate and blood oxygen data from the MAX30100, displaying it on the screen.

At the end of this tutorial, you would know how to interface Arduino boards with the STONETech displays, and also how to interface sensors like the MAX30100 with the Arduino.

Our development process for today’s project will follow this outline. We will first create the GUI for the project after which we will proceed to write the firmware to interface the microcontroller with the display.

There are two major ways of creating a GUI. One is to create the GUI using only the elements (buttons, text boxes, etc) that are available within the GUI Design tool, while the second is to create a mockup image using image editing tools like Photoshop/Paint.NET, import the image into the GUI Desing tool software and place the GUI design elements on the image. For this tutorial, we will go with the second option as it allows more flexibility and gives room for the development of truly beautiful GUIs.

The design is quite simple, we illustrate label elements to hold the date, the project title, and the values from the microcontroller. The values from the microcontroller include; the status of the connection between the microcontroller and the display, the heart rate, and the oxygen levels.

With the GUI Image done, we then proceed to import it into the STONE TECH GUI tool. This obviously mean we need to install the STONE TOOL first, so head over to the STONE Tool GUI Designer page and download it. The STONE TOOL software requires no installation and it can be directly opened and run by decompression on your computer.

It should be noted that while compatibility with other OS is currently being considered, the current version of the software only supports Windows 8 and 10 operating systems.

1. With the software downloaded on your computer, launch it and go to File>New Project. This will launch the “New Project dialog box ” where you will be expected to fill in the details of your display, set the storage path, and the name of your project. Since we will use the STVC035WT-01 display which has a  resolution of 320*480 and a default flash space size of 128Mbyte (expandable to 1024MByte), I have entered its details as shown in the image below. If you are using any of the other StoneTech displays, you will need to enter the details of that display instead.

2. Next, on the left side of your screen, you will see the project tree (under the project window) with its assets. Expand the Picture file, and delete the 0.jpg image inside it by right-clicking on it, and selecting “Remove”. For every new project, the 0.jpg file is always created as the default background for your UI, since we will use our background (the one we designed with photoshop), we can delete it.

3. Next, we need to add the background we designed with photoshop into the picture file. Right-Click on the “Picture” directory and select “Add”. This will open a dialog box for you to navigate to where the JPG version of our photoshop images is stored.

4. Next, we add fonts to the project’s assets to determine how texts appear on the display. Right-click the “Font” file, and select the appropriate font to add to the project. For this tutorial, we will use the ASCII 24 by 48 font. With that done we are now ready to begin adding the GUI elements.

7. With all of these done, we compile the GUI and upload it to the screen. To do this, click on button 1 in the image below to Compile the GUI design and click on button 2 to upload the GUI to your display.

Uploading the GUI display requires you either connect the display directly to your computer or you put the GUI on a flash drive and plug the flash drive into the USB port of the display. Because of the little complexity associated with the second option, we will be going with it.

Plug the USB flash drive into the computer then click the “Download to u-disk” button on the STONE GUI TOOL.With the “download to u-disk” process complete, pull out the USB flash disk, insert it into the USB interface of the display module and wait for the completion of the upgrade. When the upgrade is completed, there will be a prompt sound.

The model of the STONE display being used for this tutorial communicates via RS232, as such, to be able to interface the display with the Arduino, we have to connect it through a MAX3232 chip. This extra requirement can be avoided by using one of the STONE displays with a TTL interface.

Go over the connections once again to be sure everything is properly connected. With this done we can now proceed to the Arduino code to send commands and data to the LCD.

Due to the simplicity embedded in the design of STONETECH displays, the microcontroller’s interaction with any of the GUI components is usually via the “memory address” of each component. for instance, to send a message to the display from the microcontroller (the Arduino in this case), the message has to be published to the memory address of the GUI Component (in this case, the text-display component). The same holds for GUI Components that are meant to send data to the microcontroller, as the microcontroller has to poll their memory address to obtain information from them. As a result of these, we need to obtain the memory address of all the GUI components before proceeding. For each GUI component, the memory address is usually listed among the properties of the component, under the property toolbar, at the right-hand side of the STONE TOOL interface.

With this obtained, we can now proceed to write the code for the project. One of the good things about using the STONETech displays is the fact that you don’t need a library to write code for them because of their simplicity, but since we will use serial communication, we will use the software serial library to avoid having to use the hardware serial port on the Arduino Uno. To interface with the MAX30100, we will also need to install the MAX30100 library. The Max30100 library can be installed using the Arduino Library Manager or by downloading it from the attached link and installing manually by extracting the file, copying its content and pasting it in the Arduino libraries folder. The software serial library comes pre-installed with the Arduino IDE.

>With the libraries installed, we now have all we need to write the Arduino Code. As usual, I will do a brief explanation and attach the complete version of the code under the download section.

Next, we provide the customized commands that will be sent to the screen to store data in the memory address. The commands are the same for all the elements with the only difference being the memory address.

Next, we specify the variables; Reporting_Period_MS and tsLastReport, which will be used to determine when the sensor should be refreshed. With this done, we then move to the void setup() function.

We start the function by initializing serial communications between the screen and the microcontroller setting the baud rate to 115200. We also initialize hardware serial communication so we can use the serial monitor on the Arduino IDE for debugging purposes.

To wrap up the void setup() function, we increase the current of the IR LED on the Max30100 beyond the default 50mA. With this done, we move to the void loop() function.

With the code complete, connect your Arduino board to your computer and upload the code to your setup. Place a finger on the Max30100 and after a while, you should see the live pulse rate and oxygen levels appear on the display as shown in the image below.

While this project only demonstrates less than 35% of the capabilities of the STONE TECH display, it provides a good foundation for you to build amazing projects. As an engineer, the key benefit of the display to me is the ease of use both in the creation of the GUI and also the development of the code to tie it together with a microcontroller. The fact that the display doesn’t require any library makes it perfect for use with any language and any microcontroller with serial port access.

LCD connected to this controller will adjust itself to the memory map of this DDRAM controller; each location on the LCD will take 1 DDRAM address on the controller. Because we use 2 × 16 type LCD, the first line of the LCD will take the location of the 00H-0FH addresses and the second line will take the 40H-4FH addresses of the controller DDRAM; so neither the addresses of the 10H-27H on the first line or the addresses of the 50H-67H on the second line on DDRAM is used.

To be able to display a character on the first line of the LCD, we must provide written instructions (80h + DDRAM address where our character is to be displayed on the first line) in the Instruction Register-IR and then followed by writing the ASCII code of the character or address of the character stored on the CGROM or CGRAM on the LCD controller data register, as well as to display characters in the second row we must provide written instructions (C0H + DDRAM address where our character to be displayed on the second line) in the Instructions Register-IR and then followed by writing the ASCII code or address of the character on CGROM or CGRAM on the LCD controller data register.

As mentioned above, to display a character (ASCII) you want to show on the LCD, you need to send the ASCII code to the LCD controller data register-DR. For characters from CGROM and CGRAM we only need to send the address of the character where the character is stored; unlike the character of the ASCII code, we must write the ASCII code of the character we want to display on the LCD controller data register to display it. For special characters stored on CGRAM, one must first save the special character at the CGRAM address (prepared 64 addresses, namely addresses 0–63); A special character with a size of 5 × 8 (5 columns × 8 lines) requires eight consecutive addresses to store it, so the total special characters that can be saved or stored on the CGRAM addresses are only eight (8) characters. To be able to save a special character at the first CGRAM address we must send or write 40H instruction to the Instruction Register-IR followed by writing eight consecutive bytes of the data in the Data Register-DR to save the pattern/image of a special character that you want to display on the LCD [9, 10].

We can easily connect this LCD module (LCD + controller) with MCS51, and we do not need any additional electronic equipment as the interface between MCS51 and it; This is because this LCD works with the TTL logic level voltage—Transistor-Transistor Logic.

Pins 7–14 (8 Pins) of the display function as a channel to transmit either data or instruction with a channel width of 1 byte (D0-D7) between the display and MCS51. In Figure 6, it can be seen that each Pin connected to the data bus (D0-D7) of MCS51 in this case P0 (80h); P0.0-P0.7 MCS-51 connected to D0-D7 of the LCD.

Pins 4–6 are used to control the performance of the display. Pin 4 (Register Select-RS) is in charge of selecting one of the 2 display registers. If RS is given logic 0 then the selected register is the Instruction Register-IR, otherwise, if RS is given logic 1 then the selected register is the Data Register-DR. The implication of this selection is the meaning of the signal sent down through the data bus (D0-D7), if RS = 0, then the signal sent from the MCS-51 to the LCD is an instruction; usually used to configure the LCD, otherwise if RS = 1 then the data sent from the MCS-51 to the LCD (D0-D7) is the data (object or character) you want to display on the LCD. From Figure 6 Pin 4 (RS) is connected to Pin 16 (P3.6/W¯) of MCS-51 with the address (B6H).

Pin 5 (R/W¯)) of the LCD does not appear in Figure 6 is used for read/write operations. If Pin 5 is given logic 1, the operation is a read operation; reading the data from the LCD. Data will be copied from the LCD data register to MCS-51 via the data bus (D0-D7), namely Pins 7–14 of the LCD. Conversely, if Pin 5 is given a voltage with logical 0 then the operation is a write operation; the signal will be sent from the MCS51 to LCD through the LCD Pins (Pins 7–14); The signal sent can be in the form of data or instructions depending on the logic level input to the Register Select-RS Pin, as described above before if RS = 0 then the signal sent is an instruction, vice versa if the RS = 1 then the signal sent/written is the data you want to display. Usually, Pin 5 of the LCD is connected with the power supply GND, because we will never read data from the LCD data register, but only send instructions for the LCD work configuration or the data you want to display on the LCD.

Pin 6 of the LCD (EN¯) is a Pin used to enable the LCD. The LCD will be enabled with the entry of changes in the signal level from high (1) to low (0) on Pin 6. If Pin 6 gets the voltage of logic level either 1 or 0 then the LCD will be disabled; it will only be enabled when there is a change of the voltage level in Pin 6 from high logic level to low logic level for more than 1000 microseconds (1 millisecond), and we can send either instruction or data to processed during that enable time of Pin 6.

Pin 3 and Pin 15 are used to regulate the brightness of the BPL (Back Plane Light). As mentioned above before the LCD operates on the principle of continuing or inhibiting the light passing through it; instead of producing light by itself. The light source comes from LED behind this LCD called BPL. Light brightness from BPL can be set by using a potentiometer or a trimpot. From Figure 6 Pin 3 (VEE) is used to regulate the brightness of BPL (by changing the current that enters BPL by using a potentiometers/a trimpot). While Pin 15 (BPL) is a Pin used for the sink of BPL LED.

4RSRegister selector on the LCD, if RS = 0 then the selected register is an instruction register (the operation to be performed is a write operation/LCD configuration if Pin 5 (R/W¯) is given a logic 0), if RS = 1 then the selected register is a data register; if (R/W¯) = 0 then the operation performed is a data write operation to the LCD, otherwise if (R/W¯) = 1 then the operation performed is a read operation (data will be sent from the LCD to μC (microcontroller); it is usually used to read the busy bit/Busy Flag- BF of the LCD (bit 7/D7).

5(R/W¯)Sets the operating mode, logic 1 for reading operations and logic 0 for write operations, the information read from the LCD to μC is data, while information written to the LCD from μC can be data to be displayed or instructions used to configure the LCD. Usually, this Pin is connected to the GND of the power supply because we will never read data from the LCD but only write instructions to configure it or write data to the LCD register to be displayed.

6Enable¯The LCD is not active when Enable Pin is either 1 or 0 logic. The LCD will be active if there is a change from logic 1 to logic 0; information can be read or written at the time the change occurs.

Have you ever asked yourself what LCD is? No worries, we are here for you. Therefore, like in any display gadget, liquid crystal display coordinates with a microprocessor or microcontroller. The MCPU and MCU send the brightness that every pixel should produce. It creates the required color of the pixel for your LCD screen.

However, the mode of communication between the MPU/MCU and an LCD segment is known as the interface. We shall discuss more of the LCD interface in this guide.

The LCD interface is a link between the flat panel display module and the multimedia processor. Therefore, the interface can be separated or incorporated as part of the structure on the chip. Additionally, the application produces an image, and then the screen displays it using an LCD interface for the user.

The Serial Peripheral Interface is a data bus with several lines for the data. It accurately harmonizes the two ends of the data transmission. Therefore, the signal clock rotates, indicating when to sample the data bits on the line.

Besides,  the serial peripheral interface has another component known as the slave select (SS) or chip select. The function of the SS is to wake the peripheral to receive or send data. For instance, since the SPI can support several peripherals, the SS can wake particular peripherals instead of all. Finally, you can use the SPI in graphic, character, digit, and small TFT LCDs. It allows simple interfacing, affordable hardware, and faster speeds than in the SCI.

It is another serial interface in LCDs that resembles the SPI with slave, clock functions, and master. The I²C does not integrate the SS line as in SPI. Therefore, a process known as addressing is essential in selecting a slave to communicate. A frame of the signal is sent on the data bus to address a specific slave after the first bit. Nevertheless, the output signal gets to every slave connected with, although only the slave with the corresponding address to the signal will receive the message.

The MCU interface is essential because it can write and read data stored in the internal frame bugger or the gadget"s storage. Therefore, if you want to store images for future use, MCU is the best match for you.

Additionally, in MCU parallel interface for Liquid Crystal Displays, data signals are sent through data lanes on either 18-bit, 16-bit, 9-bit, or 8-bit data channels. Besides, the MCU interface is simple, although it requires a display RAM for its memory functionality. Also, you can use it in graphic LCDs, character LCDs, and small TFT LCDs.

LVDS is an acronym for Low-Voltage Differential Signaling. This type of interface is essential as a complement for large LCDs and peripherals that require high bandwidth, such as HD graphics and fast frame rates. Therefore, it is a good choice due to its fast data transmission while consuming low voltage. One of the LVDS interface wires carries the precise inverse of its companion. Additionally, the electric charge from one wire is correctly masked by the other wire, reducing the interference to the wireless system nearby. Finally, at the recipient end, a circuit checks the variation in voltage between the two wires.

Red Green and Blue (RGB) interface functions are to link with color displays. It transmits 8 bits of data for each of the colors in every clock oscillation. Therefore, this means there are 24 bits of data sent for every clock oscillation.

Currently, you must have seen an improvement in terms of performance as electronic devices become smaller and easy to use. Therefore, this has led to the introduction of an embedded display port. The interface connects a video device to a display device and carries USB, audio, and other data forms. Moreover, this display port offers a high-performance external A/V interface hence high display resolutions of 4K. Additionally, the motive behind the development of this interface is due to several computing requirements. First of all, the main requirement is hardware integration.

This is a new technology development from the MIPI alliance. Mobile Industry Processor Interface has become a preferred option for mobile developers. This interface uses the same signaling as in LVDS. It uses a clock pair and 1-8 data lanes. Mobile Industry Processor Interface supports complex rules that allow low power and high-speed modes. Additionally, it reads data coming from the display at low rates.

When choosing the correct display interface for your device, you need to consider several factors. Therefore, it requires you to know how to connect the display to your electronic system. Nevertheless, it would be best if you choose the correct interface for your display. Additionally, consider the amount of data transferred and the refresh rate your system requires.

Finally, we have made it easier as we have given you all the details on each display interface, including the pros and cons. Therefore, having gone through our guide, you will never have issues when making your choice.
