One-wire programming method for FT9xx documented?
(1/1)
Rayman:
It would be convenient to be able to reprogram the FT9xx using a microcontroller that will be on the same board.
But, to do this, would need details on the 1-wire programming method.
Is this documented somewhere?

Rayman:
Ok, thanks. That's what I figured... I saw "Proprietary" somewhere about this...
Can I use just a 2 or 3 pin header from the programmer board to the board with the FT93x chip on it?
Do I just need the DBG and GND signals to program? Or, do I need reset# too?
BRT Community:
Hello,
As a minimum, DEBUG and RESET signals are required with GROUND.

Thank you, that sounds good. 3-pin connector is not so bad to add. Might use Servo cable...
