Good morning,
Is it absolutely mandatory to use the official 4D programming cable ? As after all, it's a serial cable.
Reason I'm asking: I just received my uoled display for prototyping, and of course I completely forgot about the cable. I do have a FT232 cable lying around, with a jumper to select power supply level (3.3V vs 5V).
When I use it (and connect it the proper way), at plug time the "comms" tab does detect the display correctly, but any subsequent scan (and of course upload) fails ("Device not responding"). If I reverse TX/RX of course I don't get any response even at first plug.
So what is odd is that the cable is able to detect, but fails to communicate afterward. It always detect at first communication.
Revision displayed by detection does match displayed information once screen has powered up (SPE2 rev 1.1, Pmmc rev 2.4, com 9600)
I would REALLY welcome to be able to use my cable. Otherwise I need to order one, which means an additionnal delay (not to mention 25 euros +shipment for a simple USB-serial cable - I paid mine about 3 euro... hefty margin).
Thanks for the help
Regards
