Hello,
I want to read an hex data on a serial communication (UART) from RFID component.
After I read the data, I want to use the data for bits operations and after that to show on a serial monitor.
I've seen in the forum few examples which supposed to work, but it didn't work for me.
it will also help me if I will be able just to convert the data to ascii so I can see the data on the serial monitor.
by the way, I'm using Wemos D1 based on esp8266.
hope someone can help and send me some working example.
Thank you,
Ofir.
