Greetings.I've entirely stuck with this problem.MCU: STM32F407VGT6Realization: custom PCB and F4 Discovery board.Problem: Microcontroller can't gather information from encoders.Description: There are three motors with built-in encoders that I want ...

After a little research. I figured out that there was incorrect usage of LL_TIM_IC_Config() function. For this function it's necessary to use full LL lib with timer and GPIO structures. CubeIDE generated the code with dedicated commands for configuri...

Thank you for your support. I've generated code in CubeIDE for the LL library and copypasted it in my project. Now everything works fine.:grinning_face:

With HAL and STM32CubeIDE Timer 2 works fine. Though, the time of a foreign code refactoring coming... :worried_face: Thanks for the significant support, and have a nice day!

Also, I've checked the same code on several F4 Discovery boards. Registers CCMR1 on all Timers (1,2,3) are staying the same with value 0x0.On discovery boards odometry signals going directly in a chip (5V). Voltage drops to 2.4 V on input pins (highe...
