WebAug 13, 2024 · 1. I'm trying to configure the baudrate of USART1 on an STM32L152. When using the external Clock the baudrate is half of what I configured (e.g. 57600 instead of 115200). However, when using the internal HSI everything is correct. The internal is 16 MHz and the external is an 8 MHz crystal that is used to drive the PLL for a 32 MHz system clock.
