USING ADITIONAL USART IN STM32WL55

[nithish.h99]

Hi ,

I am trying to use 2 usart in stm32wl. But right now I am using Single uart which default PA2 and PA3 we can access through debug port, But I am trying to use through other gpios or pins through ttl But the output is not coming in terminal if I changed the pins. So is there any software or hardware changes to be made.

Thank yo

Hello Nithish,

USART2 is accessed through PA2 and PA3, you can use USART1 if you need which is on PB6 and PB7 or alternatively on PA9 and PA10, you can refer to your product datasheet for more information.
