Let's Control It

Hello

I’m recycled old,esp-01 to monitor 2 pulse counters and one ds18b20. Programmation firmware last Build is fine

I tried to use gpio 0, 2 and 3

When configuring on gpio 3 the ds18b20 or pulse counter it doesn’t not work

Is there a trick to release this port 3?

Thank’you

You need to disable the serial port to use GPIO 3. After that it should work.

oh yes, I forgot that ! Thank you

Could be nice to add it ti wiki
