Was looking at this a little more and I'm wondering about saving some GPIO pins and using a 74HC595 Shift register. I would need to research more but I though if I had a uint8_t that mapped to the output of the shift register I could just use a PIO to keep the outputs updated?
Is this something that would work the PIO would only be used to display what was in the uint8_t the flashing would be done with a timer or something.
I have 4 LEDs in the current design that use GPIO plus I want to add to that 2 more status LEDs. The shift register starts to make sense.
