Doing a little research and I think my problem is pinout of the usbasp does not match the pinout on the controller module in order to program the Attiny841-ssu.

At first in Stuart’s video I seen he was using a 10 pin connector from the usbasp in that pin one of the connector was connected to pin one of the control module and I made sure I did the same. But now that I think back on it he had rewired the ribbon cable on to the usbasp itself. And I did not I just used it the way it was set up from the factory. The ribbon cable is plugged into the connector on the usbasp and I just took the other end with the 10 pin connector and put pin one to pin one of the controller module just assuming that it was correct.

So when I get home from work I will verify which wire goes to what pin. I just found a schematic of the wiring diagram from the usbasp to the attiny841.

Below is a photo of the schematic of my usbasp factory 10 pin connector if anyone knows off hand if it is wired correctly or not to join up to the controller module without changing anything

I just hope if the wires are wrong I didn’t burn up 5 different attiny841’s this morning trying to get it to work😞

Now that I’m looking at the photo I can see why it’s not working LOL.

Pin 7 - SCK is not connected to the controller module PCB since it only has a 6pin connector
