https://devzone.nordicsemi.com/f/nordic-q-a/68615/running-libuarte-on-both-uarts-with-freertosI would like to switch to using libUARTE for both of my UARTs but I don&#39;t have any additional timers free. Is it possible to do this and use FreeRTOS timers?

Note that the FreeRTOS implementation of app_timer is missing some of the functions used by libUARTE, and needs to be implemented. <a href="https://devzone.nordicsemi.com/f/nordic-q-a/65107/app_timer_freertos-doesn-t-provide-implementation-for-app_timer_cnt_diff_compute-and-app_timer_cnt_get">This post</a> may help.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
