Example Description

This example describes how to use TIM1 complementary channel, dead zone insertion, and brake functions.

In this example, Main clock is configured at 24MHz.

TIM1_CH1 PD4 Output PWM waveform with frequency of 10KHz and duty cycle of 42%.
TIM1_CH1N PD5, as the complementary output channel of CH1, outputs PWM waveform with frequency of 10KHz and duty ratio of 58%.
The deadband insertion value is 11, the operating frequency of TIM1 is 24MHz, and the deadband insertion time is 458ns.
TIM1_BKIN PC5 as the input source of brake signal, the high level is effective, when the brake signal input is high, the PWM output
is suspended, PD4, PD5 keep the low level, and the output is resumed when the brake signal is low.
