SSD1351

Golang module for SSD1351-based OLED's on a Raspberry Pi

This module was developed for https://www.waveshare.com/wiki/1.5inch_RGB_OLED_Module, but should work with other OLED's (128x128, RGB) based on the SSD1351 as well.

Requirements

• A user with access to /dev/mem or /dev/gpiomem (possibly root)
• The SSD1351 connected to SPI0 (go-rpi only supports SPI0 at the moment)

Example usage

RPi GPIO	OLED
MOSI0 (GPIO10)	DIN
SCLK0 (GPIO11)	CLK
CE0 (GPIO8)	CS
GPIO24	DC
GPIO25	RST

rstPin := rpio.Pin(25)
csPin := rpio.Pin(8)
dcPin := rpio.Pin(24)
oled, _ := ssd1351.Setup(rpio.Spi0, 0, rstPin, csPin, dcPin, true)
oled.Init()
color := ssd1351.RGBto16bit(0xFF, 0x00, 0x00)
_ = oled.DrawBlock(0, 0, 128, 128, color)
time.Sleep(500 * time.Millisecond)
oled.Shutdown()
