RAK3172 + RUI3 + LPTIM

Hi, I’m new to RUI3 and Rak platform. How I can use PB5 pin for LPTIM with RUI3?.
Pls help me.
Thank you !

Hi @linhbui ,

The RUI3 has APIs that is inspired on Arduino. The documentation is here - Arduino API | RAKwireless Documentation Center

Have a look on the APIs and see the implementation possible on your PB5 functionality.
