stm32f4xx_it.c:153

This function handles TIM3 capture/compare interrupt.

main.c:410

Timer capture/compare interrupt processing

main.c:180

This function enables the peripheral clock on TIM2 and configures TIM2_CHTIMB_CHX as PWM output. It enables also the peripheral clock for GPIOA and configures PA.06 as alternate function for TIM2_CHTIMB_CHX.

main.c:112

This function enables the peripheral clock on TIM3, configures TIM3_CH1 as input and enables the capture/compare 1 interrupt It enables also the peripheral clock for GPIOA and configures PA.06 as alternate function for TIM3_CH1.

main.c:253

Changes the frequency of the PWM signal.

main.c:268

Initialize LED2.

main.c:292

Set LED2 to Blinking mode for an infinite loop (toggle period based on value provided as input parameter).

main.c:307

Configures User push-button in GPIO or EXTI Line Mode.
