ST7735, ILI9163, ST7789, ILI9341

Driver for ST7735, ST7789 and similar LCD screens using SPI. The ST7735 driver also works for ILI9163C.

import { ST7789Driver } from "@devicescript/drivers"
import { ST7735Driver } from "@devicescript/drivers"
import { ILI9341Driver } from "@devicescript/drivers"

WaveShare Pico-LCD shield

I8080 not supported

The drivers use the SPI interface. The parallel interface (I8080) is not supported at the moment.

Hardware configuration​

  • Configure the SPI connection
import { spi } from "@devicescript/spi"
import { pins } from "@dsboard/pico_w"

spi.configure({
    mosi: pins.GP11,
    sck: pins.GP10,
    hz: 8_000_000,
})

Display​

The driver implements the Display interface and can be used as various services. Using the driver through services provides a better simulation experience.

Driver​

The devicescript-waveshare-pico-lcd uses the driver for a WaveShare Pico-LCD shield.
