    I spoke too soon, and was only checking the first station before. Even on the latest version of OpenSprinkler-Firmware freshly compiled/configured, I have an issue on either board. If I turn on station 1, it turns on fine, which is why I thought my friend’s board was working. However, if I turn on station 2, stations 1 and 2 come on. If I turn on station 3, stations 3, 2, and 1 turn on, and so on.

    Any ideas? This is true of both OpenSprinklerPi boards, and the Saleae capture (after some hacks to only turn on 1 set of outputs, 8 bits/stations) looks perfect, so I no longer think it’s software, even though I did this morning.

    Further confusion. My board works with the other Pi which is still running the old/original python code. I pulled a capture using the Saleae and the output looks “cleaner” and another thing is the OE pin is toggled while writing. That’s something the new unified code doesn’t do, so I’m wondering if something there affects timing or sensitivity on the shift register. I’m fine talking to myself as I go through various things to test, but anybody with additional debugging ideas, feel free to chime in! 😉

    The picture didn’t come through, so here it is again: https://i.ibb.co/DK4md6z/Screenshot-from-2020-05-27-14-30-04c.png

    But, I have an update. I have a friend that also had the 1.0 board that he’s no longer using. I purchased it from him and found out it’s definitely my OpenSprinklerPi board. Booting my pi, running the same software works with the other board. I’m thinking it’s just the 74HC595 and will try to debug that further tomorrow before ripping that chip off the board to try replacing it so I have a spare board.

    I actually bought a new OpenSprinklerPi board, so I’ll be set for my stations with/without expansion boards, and have backups if something goes wrong.
