Dear,
I have a problem displaying rfd data on the nextion display (nextion enhanced 3.5″). I use the nextion library on serial 2 and the library downloaded from this site for rfid.
the programs individually work, in the same program the rfid no longer reads the tags.
do you have a suggestion?

Hi.
Without further details, it is very difficult to understand what might be wrong.
Does the code throw any errors?
Regards,
Sara

Is there a possibility that both the display and the RFID use the same pins? Or, if using SPI, the same address?
Unless somebody has the exact same setup as you it will be very difficult to troubleshoot. You will have to try different things within your code to debug. If you could use a separate UART to output data via the USB port to the computer you could write data at various points to see where the program is stopping. If not, you could just flash a LED at various points to see where the code is stopping.
