 All right, lady. What's this? There's some beautiful color bars. This is the color bar demo Register setting for the ICN 6211 which is the chip that I'm using to convert DSI from the Raspberry Pi 5 To this RGB TTL display this four inch round 720 by 720. I just got the SPI init code working Turns out you have to set the bits in the order that they come in Who would I know? So that once that got working and had all the LEDs turn on and off The next step is to verify that this config works And so you have to set the resolution and the v-sync h-sync, you know, whatever porches PLLs and then there's a bit you can set It's called the best mode where you can set different tests. So this is the Searching color bar chessboard Outline and color switch and these allow you to test that the TTL connection works So I'm still not using data from the Raspberry Pi yet. This is just running directly from the ICN 6211 I am programming it using blink up from the Raspberry Pi using I squared C so I can like trial the different settings So far so good. So SPI works I square C works the last pieces to get the device to overlay going
