A display interface that is common for TFT displays is the combination of the 3-wire Serial Peripheral Interface (SPI) and the 16/18/24-bit RGB parallel interface. The two interfaces are used in a sequence to communicate data to the display. This note will discuss how to set up a display using the 3-wire SPI+24-bit RGB parallel interface.

The 3-wire Serial Peripheral Interface (SPI) and the 16/18/24-bit RGB parallel interface are used in a sequence to communicate data to the display. The SPI interface is first used to initialize the display parameters through command registers. Once initialized, the display can receive data over the RGB parallel interface at a higher speed. This data can be sent in segments of 16, 18 or 24-bit lengths depending on what is specified by the SPI initialization commands.

The display used in this application note is a 3” TFT with 854x480 pixels. This display has high resolution and high color which requires a faster interface so the pixel clock can maintain a 60Hz frame rate. The part number for this display is E30RA-FW400-N. Details of this display are described below.

The display is connected to a graphics controller over a 24 parallel data bus and the display’s signaling pins. A graphics controller is used in addition to a microcontroller to provide the high-speed clock signal required to support this resolution and color depth. The connections to the graphics controller in the following table can be changed to connect to a single microcontroller, if the device has RGB parallel dedicated pins. The minimum requirement of RAM reserved for the frame buffer is calculated as (480 pixels x 854 pixels x 24bits/pp) 1.23 MB which will need to be provided by the microcontroller, graphics controller or external memory.

There are 45 pins that are required to be connected to the graphics controller. This includes the 3-wire SPI interface pins and the 24-bit parallel RGB data pins. This display is operated at a low voltage of 3.3V which can be provided by the microcontroller. The display has an additional feature of IPS view, and a bright backlight operated at 19.2V. The backlight voltage will need to be provided externally to the display. Below are the pin functions and connections between the display and the controller.

The serial interface clock is run at a lower frequency of 2Mhz. This frequency was chosen to maintain signal integrity and can be changed to any value between 1-15Mhz for this controller. At higher frequencies, noise can become a factor and create errors when sending commands and data. Since the SPI interface is only used to send 8-bit commands to initialize the display, it does not require a high frequency clock. This makes it possible for a basic microcontroller to provide these signals without the use of the graphics controller.

The DCLK signal is determined by the resolution, porch settings of the HSYNC and VSYNC signals and the frame rate of the display. The frame rate is standard at 60Hz, which is the minimum frequency to maintain an image. The timing parameters of the HSYNC and VSYNC signals are specified by the controller. Below are the timing parameters specified in the ST7701S datasheet and the displays datasheet.

The total HSYNC period for this display is calculated as the total time in DCLKs for one line, including the time where the pixels are not active. In this example, this value is calculated to be 480+50+10+2=542 DCLKs. The total VSYNC period for one frame of pixels to be displayed is calculated in the number of lines. The total time it takes for one frame of pixels is 854+30+10+2=896 lines.

The dot clock (DCLK) signal is determined by these two totals and the frame rate in order to maintain the image at 60Hz. The calculation of the DCLK signal is as follows: 542 x 896 x 60 = 29Mhz. This is a high clock speed for the RGB interface. The maximum clock speed for the RGB parallel interface with this controller is 33MHz. Certain steps should be taken to reduce noise on this signal to ensure reliability of the data transmitted.

The 3-wire SPI interface is used to send 8-bit commands and data to initialize the display. Each of these commands can be found in the specification sheet for the display’s embedded controller IC ST7701S. These commands specify the selection of color format, resolution, timing parameters and power control. There are a few ways to send these commands to the display.

Most microcontrollers offer dedicated SPI interface pins for the SPI protocol. There are many code repositories available for the SPI interface so there are many options for sending these commands and data. In this application, the SCL clock signal is set at 2MHz. This lower frequency was chosen over a maximum frequency of 15MHz to ensure proper signal timing and to avoid noise. Since the SPI interface is used for a brief initialization period, high speed is not required.

Another way is to use any digital pins available and “bit-bang” the information. This is when the clock and data pins are signaled on and off in the right sequence to communicate the data. This is done when there are not specific SPI pins available. This is common with the 8051 microcontrollers where most ARM and AVR microcontrollers have an SPI interface. This option has the benefit of control over whether the data is set at the rising or falling edge of the clock signal. This can be different for each display that uses the SPI interface for initialization, so it is important to confirm in the data sheet.

SPI initialization commands for the 24-bit parallel RGB interface can be found here. These commands set many functions of the display such as: timing constraints for the RGB interface, color depth, resolution, and voltage control.

This application uses a graphics controller to increase the clock speed and provide memory. If the microcontroller is providing the RGB function to the display, then this step can be skipped. The graphics controller used in this application is SSD1963. This graphics controller provides the memory for the frame buffer of the display. The DCLK signal is also generated by this controller to an RGB PLL setting of 29MHz.

The RGB interface pins are connected to the graphics controller in parallel. This application uses the 24-bit interface so all 24 data bus pins must be connected to the controller. The HSYNC, VSYNC, DE and DCLK pins are also connected to this controller. The graphics controller is controlled by commands over a 16-bit parallel MCU interface. These pins will need to be connected to the microcontroller to send the initialization commands as well as the data that will be projected on the display.

The initialization of the graphics controller will specify the desired DCLK speed that is needed for the RGB interface. These commands are sent by the microcontroller in sequences of 8-bits. Because the commands are 8-bits, it is possible to send the data over an 8-bit parallel interface. The commands that are used to initialize the graphics controller are reviewed in the data sheet of the IC SSD1963. The commands that were used to initialize the graphics controller can be found here.

The RGB interface can now be used to transmit data to the display. The serial interface no longer needs to be used after initialization is complete. Now the 24 RGB data pins will send the 24-bits of RGB data per clock cycle. The data in this example is processed at 24bpp. This means that each pixel will have 24-bits of information for the color depth and that the display is capable of 24 million different color variations.

A brief example of how to display colors on the display will be reviewed. Displaying colors onto the screen requires sending 24-bit color data to each of the visible pixels in the display area. This can be done by writing to each location in RAM where every pixel is stored and telling it which color you have selected. This application can be used to portray bitmap pictures through the same process.

The example used to write to RAM stored on the SSD1963 controller can be found here. This process is done using the command “memory write” (0x2c) of the graphics controller for each of the pixels on the display. The colors can be sent in 6-digit, 24-bit sequences and decoded or as three 8-bit sequences representing one for each of the red, green, and blue components of the color. Below the color will be sent as components of the RGB color in three steps on eight bits to the graphics controller. The image above shows how the 24-bit data is sent to the graphics controller in sequences of 16-bits.

This lovely little display breakout is the best way to add a small, colorful, and bright display to any project. Since the 2.0-inch SPI TFT LCD Color Screen Module display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available. The 2.0″ display has 176×220 color pixels. Unlike the low-cost “Nokia 6110” and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ILI9225) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so there are no worries that your code will not work from one to the other. The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as an ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. We also had a little space so we placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card.

ST cooperates with Riverdi because we believe that such partnership brings value to our joint customers.

Riverdi offer is covering a lot of them, allowing the customer to focus on the most important part of the development, the GUI Application itself. And remember that this is the face of your product. Choosing such solution, the customer does not need to worry about sourcing components like the display, microcontrollers, memory, etc. or even writing low-level drivers, development the board support package or porting TouchGFX. Its all ready done. What makes cooperation with Riverdi unique is that Riverdi has been able to drive a 1280*800 display resolution in high colors, with a STM32H7 microcontroller and a TouchGFX application showing a smart home UI. This shows that Riverdi is well aware of how to exploit all the capabilities of the STM32 Graphics offering combining hardware and software in a unique solution. From the first business meetings, it was clear that we shared visions of the market for embedded GUIs. And Riverdi proved that they can go from an idea and concept to actual working hardware, very fast.

I have a small 3.5 in TFT LCD display from a Chinese manufacturer. It doesn"t have an integrated LCD controller. The documentation claims it is a "16 bit RGB/parallel interface" and it uses a Renesas R61581B0 driver chip.

These types of displays are very common and cheap. They sell for less than $15 a pop on Alibaba.com, but I don"t really have a high esteem for these manufacturers since they do not provide any good / consistent documentation, and their English is riddled with mistakes! But I did get the display, and the product looks and feels like it will do the job!

My question now is, how do I get started ? I have looked on the internet and cannot find a good starting point. I have a 32MHz microcontroller in mind, but I am stumped on how to interface it with the LCD.

Most display projects online that I"ve seen assume that the LCD module comes with an integrated controller , so the MCU"s job becomes pretty simple.. Provide image updates when necessary, and the controller will do the job of refreshing the LCD module at the required 60hz (or so)

This LCD module that I have has raw data lanes that I need to drive myself at 60hz. Are there any good documents on how to interface an MCU directly with such an LCD module?

I"ll be happy with any info that points me in the right direction, whether it be an answer on stackexchange or a reference to any good documentation online.
