Best not to claim the GPIO used for ADC is three *different* pins. Make them all agree with the actual code, according to the pin it ended up on. --- diff --git a/bathroomfloor.yaml b/bathroomfloor.yaml index 79ea5b2..069c66e 100644 --- a/bathroomfloor.yaml +++ b/bathroomfloor.yaml @@ -4,7 +4,7 @@ # GPIO23: Onboard blue LED (used to show MQTT connectivity) # GPIO16: Onboard relay (bathroom fan) # GPIO25: Used as output for NTC bridge -# GPIO32: ADC, midpoint of NTC bridge +# GPIO34: ADC, midpoint of NTC bridge # # The underfloor heating NTC thermistor is connected as follows: # @@ -12,14 +12,14 @@ # | # ⯠10 kΩ fixed resistor # | -# --- GPIO24 (ADC) +# --- GPIO34 (ADC) # | # ⯠10 kΩ NTC under floor # | # â GND # # Rather than leaving current flowing through the thermistor at all times and -# potentially introduicing errors by warming it up, we only turn GPIO25 on +# potentially introducing errors by warming it up, we only turn GPIO25 on # when it's time to take a reading. # # So we disable the periodic measurement on the ADC sensor, then periodically
