Moving from UART FIFO to two separate UART instances

[Sumedh]

Hi,

I have a working code that uses the UART FIFO instance which uses the app_uart_put and app_uart_get functions to communicate to an external LCD module. I want to now add an additional uart instance to communicate to an additional peripheral. However the current uart initialization (APP_UART_FIFO_INIT) does not allow for multiple instances of uart. How do I shift to using multiple UART instances?

Hi,

The Libuarte - advanced UARTE driver library supports multiple UART instances. You can have a look at this example if you want to run both instances through libUARTE. You may also continue using app_uart for one UART instance, and use libUARTE for the second instance if you prefer that.

Another alternative is to use the UART driver directly.

Best regards,
Jørgen

Do you get this from the unmodified example? Or did you integrate it into your own application?

I'm not able to reproduce this error.

Which SDK version and compiler are you using? Can you upload your sdk_config.h file?
