Here's how you draw some random colours. >>> import random >>> for i in range(400): >>> display.write(None, bytearray([random.getrandbits(8)])) You use display.write(command=None, data=your-bytes) to send pixel data to the display. To understand what it is doing, try writing the same 2 bytes, hundre...

Trying to flash the latest MicroPython to a 16M Wemos D1 Mini Pro. Hit a problem where it would get stuck in a boot loop. Initially, I thought it was a problem with make deploy not including the write esp_init_data_default.bin to 0xffc000 in the esptool.py command, like I had done manually before. W...

Normally they support writing RGB666, RGB565 or RGB444 after a few init commands.
I usually use RGB565 as it fits 1 pixel in 2 bytes, making writes faster and I often don’t need the extra colour precision of RGB666.
