Hi

 

 I just purchased the STM32L432 Nucleo board  and tried to run the example from the folder

 

STM32Cube_FW_L4_V1.8.0\Projects\STM32L432KC-Nucleo\Examples\PWR\PWR_STANDBY_RTC

 

I found that I could not find the definition for LED3 (macro label)... The question, has anyone used this example?.  I also am kind of confused what the code actually does... I set the LED3 to 0 and compiled the code and dumped it.. I cant understand how GPIOA or B or C is configured.... Any explanation in this regard and how and what the code does would be great!!! . Thanks for all the support..
