libuarte.7zThe second instance of UARTE, UARTE1, was enabled in the configuration file. The receiving interrupt of UARTE1 failed to enter. Please help to check the reason

Hello,

I can't compile the project that you sent, because TX_PIN_NUMBER1 is not defined. 

Obviously, I can set it manually, but if you changed files outside the folder that you sent me, I don't know what other changes you did. 

Can you please zip a folder that I can unzip in an unmodified SDK, that will still replicate the issue that you are seeing, so that I can have a look?

Actually, just looking over the project, to see if I could see any obvious errors, I see that you don't have an RX pin on your libuarte1. You have set both the TX pin and the RX pin to TX_PIN_NUMBER1, so if you are trying to send a message to the pin that you probably named RX_PIN_NUMBER1, then that pin is never set as an RX pin in your UART.

Best regards,

Edvin
