Custom Baud rate with UART

[RPDben]

Hi,

I am trying to run a MIDI slave chip with the nRF51822 which requires me to use the MIDI standard baud rate of 31250. Is it possible to use nrf_drv_uart with a custom baud rate such as this?

Thanks

Hi,

Yes, that is possible. It's already defined in nrf51_bitfields.h

#define UART_BAUDRATE_BAUDRATE_Baud31250 (0x00800000UL) /*!< 31250 baud. */

If you want to do other custom baudrates that is not defined in nrf5x_bitfields.h, take a look at this post for how to calculate the value of the baudrate register.

I forgot to mention, I am on sdk10.0.0. It doesn't seem to be in there for that sdk. Will it work if I manually add that define in?

[Sigurd]

Yes, that will work, just add the define.

I'll give it a go now!

Works perfectly, thanks!
