Greetings!
I created a home-brew board running a 1284P with Maniacbug's Mighty-1284 optiboot and am just getting into playing with the two 74HC595s that live on the board. I have been successful with operating the shift registers in a couple of different methods.
I then saw Elco's ShiftPWM and thought the idea of a bunch of PWM outputs looked too good to resist at least looking into. I am running it it non-SPI mode due to the traces being there before finding the library. Setup as Data on 20, Latch on 21 and Clock on 22.
Running the example sketches, I get no output at all on the pins of the uC.
Does anyone have any success in running this combination of ShiftPWM on a Mighty 1284P based board?
