STM32F446RET Core held in reset

Hi ST,I have a custom board using STM32F446RE. I followed the Nucleo board schematics for my JTAG connection except that I connect the NRST pin to vcc through a pull-up resistor(10k) to prevent inadvertent reset. The other thing is that I have a TI p...

Don't Execution SysTick_Handler(void) in LL library

Sorry for weird EnglishI try use SysTick_Handler in LL library (with STM32L011F4U and CubeMX ), but never execute the Handler.I also tried HAL library, then executed properly. So I checked difference between HAL and LL , and I recognized initializing...

Controlling CNC machine

Hi!I'am new to STM's so I thought I will learn them by making the project. I want to control a CNC machine. I started to control stepper motor via TB6600. The problem I cannot solve is setting very accurate frequency for the PWM. For example:I have 1...
