Problem with Basic UARTE Usage

Hi Sigurd,

I was really looking for an example of the API usage. I sort of struggled through most of this myself looking at various examples in the SDK code tree. The "peripheral UART" one was helpful, but it was only a polling approach and I think I need more of an interrupt driven design.

I managed to get most of it working similar to the "UART Driver Sample", but I still have to figure out usage of the TX interrupt part of the design. Hopefully this is enough to get me what I need, I'll let you know if I have any more questions on this subject.

Thanks so much for the help.

Regards,

Pam

The Zephyr version in nRF Connect SDK v1.9.1 does not have a simple UART sample.

However, in the newer Zephyr version, you can find a UART Driver Sample.

Is this what you are looking for?

Hi!

Try to use "Peripheral uart" sample as base for your development.

The implementation of UART should be usefull for you. Just set according TX and RX pin in the .overlay file or change them in the main code

        NRF_UARTE1->PSEL.TXD = PIN_TXD;
        NRF_UARTE1->PSEL.RXD = PIN_RXD;
        
        //or
        
        NRF_UART0->PSEL.TXD = PIN_TXD;
        NRF_UART0->PSEL.RXD = PIN_RXD;
