FTDI 232BM DTR-> Propeller RES line
Afternoon all,
(And a sunny one here in the UK!)
Quick question on the FTDI 232BM IC - when it's powered up it pulses the DTR line high - which has the effect of resetting the propeller (via the NPN).
The board is basically wired up the same as the USB2SER and is bus powered too.
Any idea's why, or what could be changed to stop it doing that?
Cheers,
James

I know that - I'd like to keep the ability to re-program the prop though.

I did wonder about something similar. I'll get the O'scope on it this weekend.

PS: Saluti means somewhat like greetings in Italian and since i live in the Italian speaking part of Switzerland i use
this "formula" even if my mother language is German.
Auf Wiedersehen!
