You can see in the attached PNG how to use the serial shift register. This diagram is for a 16 ch relay card. just use half for 8 relay card.

OK, Thanks for the hints. I found it in gpio_pins.py in the setShiftRegister(srvals) definition.

Seems to be working like a charm!

I forgot to include that I am using the OSPi software from Dan-in-Ca version 2.2.35. I cannot find the suggested apply_all_station_bits function so I suspect that is the interval version, or I just don’t know where to look.
