I am just wondering about the possibility of using my seeedstudio UartSB V2.2 to program a peggy 2.0 (evilmadscientist.com/article.php/peggy2) display via the USB TTL headers. I’ve been digging through the specs for both the UartSB I own and the FDTI USB TTL cables. Both run 3.3v, but the UartSB has a pin marked DTR, whereas the cable has CTS and RTS pins. Therefore the UartSB has 5 pins, and the USB ttl is expecting 6 pins in
I was hopeful I can make the USB-TTL solution I have work for programming the peggy 2.0.
Anyone have any advice about this?
