4 channels input + 4 channel output
Posted: Sat Apr 22, 2017 12:05 pmHello guys
Can someone support me on this project? I'm trying to make 4 digital inputs + 4 digital outputs at once on module ESP12E but I'm not able to make it work.
If I disable part of the code for inputs then outputs are working or oposite too however all at once looks to make module bloacket.
Thanks in advance for your help
