CLT test with software pull-up #17

Closed rusefillc closed 2 years ago

rusefillc commented 2 years ago

2chan board bench test - only miniUSB connector for power & calibration

actual behavior: "raw CLT" reports same 0.8v regardless of "boardUseTempPullUp"

Same 0v on R30 MCU side regardless of tempPull Boolean property

rusefillc commented 2 years ago

so yesterday tempPull was not actually initialized by firmware

just fixed initialization
