When updating it, the network card stopped working. Also when uploading the arduino code it gives an error
'TwoWire' does not name a type
TwoWire I2Cone = TwoWire(0);
thanks for your help

do your arduino IDE board is "NodeMCU32-S"? i have compile these code, no problem.

Hello, thanks for your instructions. I have changed the board model in the arduino ide and it still gives the same error. I can't compile any code on the board and it also gives an error in “PCF8574 pcf8574_R1…”.
Can the board be left with the factory settings? The network does not work and the arduino code cannot be compiled.
I could send an email to some address explaining what we want to do, it's for a museum project.
Thanks for your help
