Hi, I have a code in which I am controlling a PWM output in Center Aligned Mode using Timer 2 Channels 2 (inverted polarity) and 3, both having their duty cycles changed by the functions:__HAL_TIM_SET_COMPARE(&htim2,TIM_CHANNEL_2,(duty_c-0.05)*400);_...

STM32F100RBT6 TIM15_CH1 and TIM15_CH1N complementary pwm mode does not generate the complementary outputI have a problem with my complementary output generation at Timer 15 Channel 1. I have set all parameters at CubeMX and have set HAL_TIM_PWM_Start...

I want to blink a LED and I have written this code:#include "stm32f10x.h"int main(){ // initialize the clock for Port C RCC->APB2ENR |= (1<<4); // enable clock for GPIO C ( check it on memory and bus architecture) // set pin 9 of GPIOC ...

Why would it be exhausted? That's a 20kHz control application in which I change the duty cycle every 50us in order to adjust the system control base on adc values, isn't it quite normal in many power electronics and motor control applications?

I have this 50us interrupt which comes from the interrupt in order to change the pwm duty cycle using HAL_TIM_SET_COMPARE, and inside my main I have this HAL_Delay(1) which I use to control the LCD. It works fine when I do not insert that HAL_TIM_SET...

I am sorry, I made a mistake stating I had no function in my interrupt handler, Actually I do which is the _HAL_TIM_SET_COMPARE. Even though when I try to change it writing directly to the register (htim2.Instance->CCR=xx ; ) the same bug happens. I ...

I thought of increasing SysTick priority but I realized that all functions in the interrupt table are assigned 0 priority (highest), so should I decrease all the others to 1 and leave SysTick as 0?Additionally, I am not calling any function inside th...

Function : __HAL_TIM_SET_COMPARE(&htim2,TIM_CHANNEL_3,(duty_c)*400); is disturbing my 16x2 LCD routine which demands a delay to receive and display data on the screen.

STM32F100RBT6. I left HAL libraries behind and want to work writing straight to the registers but something is wrong and it does not work.
