    Programming RF1s

    I have four RF1s that I'm trying to program with a Komby FTDI and I'm getting the infamous "not in sync" errors on upload. I can pull the chips out of the RF1s and put them in an Uno and they program just fine.

    Is there any way to verify the FTDI is working properly?

    Basically means it dosen't think you have anything attached.

    What ftdi adaptor do you have?

    Ether the reset line is not working right.
    Or try swaping tx and rx.

    I'm using a Komby programmer - - and I verified that the FTDI chip is good. The serial console works fine so it appears that the reset line is not working properly.

    I'll try rigging a manual reset button into the circuit to force RST low and see if that makes a difference.
