Jan 31, 2022 · 2. When configuring a STM32 (or at least my STM32F722ZE based nucleo board), there are 2 clock frequencies, one for APB1, the other for APB2. The annoying thing is that some timers use APB1, other use APB2. So each time I want to configure a PWM (or other timer based application), I have to first check which timer is connected on which APB.

May 5, 2022 · However, changing the clocks has an effect on all attached peripherals an it looks like UART 2,3,4 an 5 are connected to APB1. When you change APB1 clock you have to re-initialize the UART baudrate. Most of the time this is done in HAL_UART_Init(), but if you change it afterwards you may need to deinit and init again.
Feb 23, 2023 · Hello @Marrkinho , To set the peripheral clock frequency for I2C as APB1 frequency (for 42 MHz ) , you need to program the bits 0-5 (FREQ [5:0]) of the I2C control register 2 (I2C_CR2) as 0x2A.
