== Summary ==<br />
The Waveshare 1.3-inch LCD module uses an ST7789VW controller, an IPS panel with 240x240 resolution and an SPI interface. It operates at 3.3 V or 5 V and is intended for Raspberry Pi, STM32, Arduino and VisionFive2.<br />

<br />
== Technical overview ==<br />
* Resolution: 240 x 240 pixels; display area approx. 23.4 mm x 23.4 mm; pixel pitch 0.0975 mm.<br />
* Controller: ST7789VW (supports RGB444, RGB565, RGB666); demos use RGB565.<br />
* Interface: 4-wire SPI (MOSI/DIN, SCLK/CLK, CS, DC, RST, BL).<br />
* Raspberry Pi wiring: VCC to 3.3 V, GND, DIN to MOSI (pin 19), CLK to SCLK (pin 23), CS to CE0 (pin 24), DS/DC to pin 22, RST to pin 13, BL to pin 12.<br />
* STM32 example based on STM32F103RBT6: DIN→PA7, CLK→PA5, CS→PB6, DC→PA8, RST→PA9, BL→PC7.<br />
* Arduino UNO example: DIN→D11, CLK→D13, CS→D10, DC→D7, RST→D8, BL→D9, VCC→5 V.<br />
* SPI protocol: CSX low enables the device; D/CX = 0 writes commands, D/CX = 1 writes data; default mode SPI0 (CPHA=0, CPOL=0).<br />
* Raspberry Pi: enable SPI via raspi-config (Interfacing Options → SPI → Yes), then reboot.<br />
* On Bookworm only lgpio is available; bcm2835 and wiringPi cannot be installed there.<br />
* VisionFive2 pins match the Raspberry Pi table: DIN→19, CLK→23, CS→24, DC→22, RST→13, BL→12.<br />

== Notes and version constraints ==<br />
* Different Linux versions support different libraries; e.g., FBCP does not work on Bookworm – Bullseye is recommended.<br />
* Power supply must match the logic voltage (3.3 V or 5 V), otherwise the module will not operate correctly.<br />
* For Arduino, a stable 5 V power supply must be connected, otherwise the display may malfunction.<br />
* Pin mappings can vary by development board; verify actual pins before soldering.<br />
* Version-sensitive steps: demo downloads and library installations depend on the operating system used.<br />
* Accuracy of pin assignments and compatibility should be confirmed by a technician before integration.<br />
