2. Complementarysignals

2.1. Function description:

This demo shows how to configure the ADVANCED_TIMERn peripheral to generate three complementary ADVANCED_TIMERn signals. ADVANCED_TIMERnCLK is fixed to systemcoreclock 8MHz, the ADVANCED_TIMERn prescaler is equal to 400, so the ADVANCED_TIMERn counter clock used is 20KHz and the PWM frequency is 1.25Hz.

2.2. Test result:

The output signal as the following description:

The channel 1 duty cycle is set to 25%.

The channel 2 duty cycle is set to 50%.

The channel 3 duty cycle is set to 75%.

2.3. IO connection:

NONE

2.4. Output pad:

PAD
pad_ADVANCED_TIMERn_bkin
pad_ADVANCED_TIMERn_etr
pad_ADVANCED_TIMERn_ch1_i
pad_ADVANCED_TIMERn_ch2_i
pad_ADVANCED_TIMERn_ch3_i

Note

The ‘m’ and ‘n’ in “advtimer_timerm” and “advtimer_timern” indicate the peripheral number.
