help me M5Stack ATOM RS232.
-
Greetings to the whole community.
I have a problem with an M5Stack ATOM RS232 Voltage Converter Development Kit (MAX232). I can't read data from an inverter. if I connect it via DB9 everything works normally. I would like to understand if I'm the one doing something wrong or there is something to do that I don't know.
thanks in advance everyone.
