there's three parts to getting these funky displays working with raspberry pi over the DSI port: the SPI configuration of the screen, the I2C configuration of the ICN6211 converter and the DTO device tree overlay on the pi itself. all must be perfect for an image to appear! to make it less complex, we're going to only do one part at a time and celebrate the successes. first is the SPI configuration: without worrying about the ICN or DTO part, we will send the commands to the display from an on-board attiny chip and then toggle all the pixels on and off using commands 0x22 and 0x23. makes it look like a gigantic LED. but now that we see it working, we can move onto the next stage...ICN6211 config!
