Does anyone code for the STM32 microcontrollers?

I've been looking at using an STM32 board to drive some ST7735 lcd boards through SPI but my coding skills aren't upto the task at the moment. The STM32 is a whole new ball game for me and I'm trying to do something that doesn't appear to have been done, not that I can find online anyway.

I don't want to load bitmaps from an SD card, as they draw too slowly but to have the raw data stored in the microcontroller memory. It'll be a 128 x 128 colour image, just arcade sprites so the colours will be kept to a minimum.

If I can't work it out I might go with an Arduino Due or Giga when they become available. They're a lot more expensive though.

Consider ESP32 as well. Good pool of code to look at, and not so pricey.

+1 on ESP32. Plenty of code out there and have the option of making it even easier and more flexible using ESPHome, for example https://github.com/ozcantem/esphome_st7735. Added bonus of wifi and mqtt etc so can control remotely and OTA updates.

Well worth a look - the GPIO Binary Sensor should make a great trigger for a video update based on the example linked by @djc

We've made a bit of progress in getting an image to display on the lcd.

We used some sample code we found online.
