• PWM with different frequency
    Hello, i'm using an stm32f4 to control a stepper motor. I'm not sure if i need PWM mode or OC Mode or OnePulse Mode. I can generate a fixed frequency PWM wave but since i need a particular acceleration...
  • PWM Signal with variabel frequency
    I am using Keil, C51 Compiler with Infineon XC886 I want to create a PWM signal at pin 3.0, where the frequency is variable and the on time Ton is constant. I wrote the code, I initialized CCU and...
  • Hardware PWM - vary the frequency
    I'm using a Philips P89C668 at 16MHz in 6-clock mode. I've got a piezo (with internal driver) on P1.3 (CEX0). I'd like to switch to a speaker and output PWM to get different tones. However, I can't find...
  • Problem of updating frequency in PWM signal...
    Hi! I am a beginner in programming STM32f4 and that is my biggest problem, I think... I am working now on the project where I need do profile the velocity of servo motor (i.e. trapezoidal velocity...
  • change frequency of PWM for TIMER on STM32F429I
    Hi I am working on changing the frequency of the square signal which comes from STM32F4. I used Timer and ADC simultaneously where I change ARR and CCR1 accordingly to change the frequency. When I use...
