Testing ospi without valve connections

[klein1jo]

Hey,

It’s the middle of winter. In lieu of not being able to actually open and close valves to make sure an ospi is working is there any command line troubleshooting that can be done to indicate things should be working as it should?

What about my config.txt. I assume i2c is required for the lcd screen. What about i2s and spi? Anything else I should make sure I have/don’t have in my config.txt?

The firmware build script automatically handles I2C config in your config.txt:
https://github.com/OpenSprinkler/OpenSprinkler-Firmware/blob/dev/221_1/build.sh#L11
The firmware does NOT use I2S or SPI so they are not needed.

Thanks. What about my other question Ray? In lieu of not being able to open and close valves to test that the ospi works, is there anything I can run from the cli to test that the ospi works as intended? Or just as long as the LED comes on hope for the best and see what’s what in the spring?

If you have 24VAC power adapter connected, you can measure the AC (note: AC, not DC) voltage from the COM (common) terminal to a zone. When that zone is open, the voltage should be about 24VAC.

Alternatively, you can measure the DC voltage (note, DC) from +5V pin to a zone. When that zone is open, the voltage should be about 5VDC, and when the zone is closed, the voltage should be close to 0V.

I had the opposite actually. Testing COM to 1 though 8 I had to measure DC. Had 24 volts on all 8 zones. Thank you for you help.
