Resolved! STM32L010K8 TIM2_CH4 PWM can't go to PB1
A'm using LL libraty. I need simple PWM output on PB1.TIM2 init related to CH1 and PA5 work.When I change setup to CH4 and PB1 pwm doesn't go to the pin.Both PA and PB ar clocked.Under debuger I checked MODER registers, AF_5 function is selected.Work...
Why the Hyperbus frame sent from NUCLEO-L4R5ZI-P board has not the good shape?

STM32F0 CubeMx SPI HAL Driver Initial Pin Level
Hi there, I created a project with STM32F042G6 chip using CubeMX. I am interfacing this IC to another chip using SPI. When I set the SPI1 and try to send a command, just before sending a command I have SCLK, MOSI, and MISO levels are high. After send...
