I'm pretty sure you need to do the DTR mod ( https://learn.adafruit.com/ftdi-friend/programming-blank-avrs ), even to read the data.
Did that. I'll take some photos of my work, but rest assured I soldered the DTR exactly how they explained.
That page did NOT say where the white wire (DTR) goes, but since only 1 was free, I'm assuming pin #5 (next to #6 green).
I think the issue at hand might be the nootropic rgb matrix backpack pcb itself...
Here's the schematics of it:
Take care to notice pin #6 (GRN) which is green wire (not ground, cuz thats BLK).
That pin goes directly into the atmel IC pin #1, which is the RESET pin.
So everytime I execute the avrdude command, you can literally see the led board flash on and off as a reset would do. This I think may be the problem, but unsure how to fix it.
Basically the avrdude using correct -c and -p and -P would give valid signature of the atmel IC, but since it's coming back as 00 00 00 everytime, there's definitely a connection issue.
PLEASE HELP!
