I have a question: I bought one of these little colour ST7789V2 LCD displays https://docs.m5stack.com/en/unit/lcd , kind of on a whim, and I cannot get it do anything. `i2c.scan()` on an ESP32 finds the device, but I cannot work out how to send data to it. I had vaguely assumed I could throw a bitmap at it over i2c, but nope. Anybody ever made one of these work?
Please boost for reach
Well, I've learned more than I ever expected to about i2c and RGB888 images, and I've lashed together some truly upsetting Python, but it works!
Expect to see some extravagantly over-engineered code early in 2025
Gonna be wildly preoccupied with thinking about this all day
@pikesley should "Let's talk about i2c" be sung to the tune of "Let's talk about sex, baby" by Salt & Pepa?
@Floppy I think that was probably in the back of my mind when I wrote that heading tbh
