The RP2350 Feather has an FPC output connector for accessing the HSTX – high-speed transmission – peripheral. This lets us drive DVI displays really easily! Today, we got the prototype PCBs for our HSTX to DVI adapter board; after connecting up a 22-pin FPC cable, we can test out DVI driving via CircuitPython. With HSTX, we don’t need to overclock or use PIO, and there’s a lot more RAM on the RP2350, so we can easily do 320×240 with 16-bit color and have plenty of SRAM left over. It would be neat if we could do DVI from the PSRAM as a framebuffer at some point for really big displays! – video.
