Description

• PWM Application with Timer 4 and 3 Channels: Considering the characteristics of the STM32F407 microcontroller, the Timer 4 counter frequency is set to 1MHz, and the PWM frequency is set to 10kHz. Timer 4 will be configured to output PWM signals on channels 1, 2, and 4 with duty cycles of 80%, 40%, and 20%, respectively. These PWM signals will be sent to the red, green, and blue LEDs on the board. The code will be written in C.

  Note 1: Required system library ‘stm32f4xx.h’

  Note 2: The clock values for the processor are assumed to be as follows:

  Input Oscillator: 8 MHz

  System Clock and AHB1 bus: 168 MHz

  APB1 peripherals bus: 42 MHz

  APB1 timer units clock: 84 MHz

  APB2 peripherals bus: 84 MHz

  APB2 timer units clock: 168 MHz

  Timer 4 ARR: 100
