Hello,
Hardware: nodeMCU V2.0, newest lua-firmware (from build service)
After that I measure 1.1V on D6. If it is set LOW, it is 0V.
Tried the same with pin 0..8:
D0: HIGH: 3,3V LOW: 79mV, red LED on -> fine
D1: HIGH: 3.3V LOW: 0V
D2: HIGH: 1.1V LOW: 0V
D3: HIGH: 1.1V LOW: 0V
D4: HIGH: 1.1V LOW: 120mV, blue LED on
D5-D8: HIGH: 1.1V LOW: 0V
When I read the status with gpio.read() the values are as expected (0 for LOW, 1 for HIGH).
Whats wrong woth the voltage here?

Code: Select all
-- pin test
pin=6; -- for D6 n=0..8 for D0..D8
gpio.mode(pin,gpio.OUTPUT);
gpio.write(pin,gpio.HIGH);
