Has anyone integrated an FTDI?

Postby hjmiii » Sat Feb 20, 2010 3:54 pm

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.

you could use the rts/cts pins as well as tx
then you would have a button to press when you program it for 'reset'

I designed one:

However it's entirely untested at the moment. I've hooked up the control lines similarly to you - be interesting to know what the outcome is - I may want to change my design a bit.
