As a 2inch IPS display module with a resolution of 240 * 320, it uses an SPI interface for communication. The LCD has an internal controller with basic functions, which can be used to draw points, lines, circles, and rectangles, and display English, Chinese as well as pictures.

The 2inch LCD uses the PH2.0 8PIN interface, which can be connected to the Raspberry Pi according to the above table: (Please connect according to the pin definition table. The color of the wiring in the picture is for reference only, and the actual color shall prevail.)

The LCD supports 12-bit, 16-bit, and 18-bit input color formats per pixel, namely RGB444, RGB565, and RGB666 three color formats, this demo uses RGB565 color format, which is also a commonly used RGB format.

For most LCD controllers, the communication mode of the controller can be configured, usually with an 8080 parallel interface, three-wire SPI, four-wire SPI, and other communication methods. This LCD uses a four-wire SPI communication interface, which can greatly save the GPIO port, and the communication speed will be faster.

2. The module_init() function is automatically called in the INIT () initializer on the LCD, but the module_exit() function needs to be called by itself

Python has an image library PIL official library link, it do not need to write code from the logical layer like C, can directly call to the image library for image processing. The following will take 1.54inch LCD as an example, we provide a brief description for the demo.

I have once considered some STM32L4 for paralel LCD: tldr: I strongly disadvise. Save ton of time and hardware money, get mcu with ltdc and enough ram onboard and enjoy the life.

Precisely, I used FMC, no external memory. Targeted in magnificent, unbuffered 8-bit color space. Thing turned out to have to have risky, close to margin timings, depending on internal bus clock and internal FMC write fifo and timings trims. Required external gates, timers for sync pulses and wasn"t sure if lcd would approve of not ideally synchronised pulses. Plus a lot of soft to control, DMA"s 16bit item counter wasn"t enough, bla bla. Generally I dropped it, too many nasty contraints and potential, fatal pitfalls.

Today I am going to interface LCD to STM32 using an I2C device (PCF8574). PCF8574can be used as a port extender, to which LCD will be connected. If you haven’t read my previous post about I2C go check that out HERE.

Well you generally don’t but as I mentioned in my previous article that we can connect up to 128 devices on the same I2C line and let’s say we want to connect two different LCDs on the same I2C line, than we can’t use two PCF8574 with same addresses and we need to modify one of them.

As shown in the figure above, first pin of the device is Vsswhich is pin 1 of LCD. So all you have to do is connect first pins of the LCD to Vssabove and rest will connect accordingly. Starting with Vss as first pin, connection is as follows:-

As according to the datasheet of the LCD 16×2, in order to initialize the LCD, we have to use some sequence of commands. The code is commented properly, so that you can understand it better

What I understood was - ignoring the SD card module, they are using an LED driver IC to control the backlight, and a voltage regulator(with some auto reset IC) to feed the correct voltage to the LCD. Apart from that there"s some bypass caps on VCC and, some diodes on the LED driver IC.
