I'm attempting to avoid the serial to USB cable requirement by building a FTDI based usb port onto the MinPOV3. For a prototype I had an Arduino MiniUSB
adapter laying around, so based on the schematic
I wired the 5 needed pins to the equivalent ports on the MiniUSB. My PC sees the ftdi correctly as COM5, and I've made all the adjustments (Downloaded the special AVRDude and config, changed the makefile accordingly for com5). But when I try to program it just says the AVR isn't responding. I tried adjusting the delay.
Am I using the wrong pins, or are any other needed? Based on the schematic I'm sending pin 3 to transmit, 4 to DTR, 5 to ground, 7 to RTS, and 8 to CTS.
