Title: One-wire programming method for FT9xx documented?
Post by: Rayman on October 16, 2019, 11:38:41 PM
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?

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?

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...
