10. Six_steps

10.1. Function description:

This demo shows how to configure the ADVANCED_TIMERn peripheral to generate three complementary ADVANCED_TIMERn signals(for BLDC) with dead time.ADVANCED_TIMERnCLK is fixed to systemcoreclock 8MHz

For instance:

The ADVANCED_TIMERn prescaler is equal to 8 so the ADVANCED_TIMERn counter clock used is 1MHz and the PWM frequency is 1KHz.

10.2. Test result:

step 1

pad_ADVANCED_TIMERn_bkin: pad_ADVANCED_TIMERn_etr: pad_ADVANCED_TIMERn_ch1_i: output 1KHz %30 duty PWM signal pad_ADVANCED_TIMERn_ch2_i: pad_ADVANCED_TIMERn_ch3_i:

step 2

pad_ADVANCED_TIMERn_bkin: pad_ADVANCED_TIMERn_etr: pad_ADVANCED_TIMERn_ch1_i: pad_ADVANCED_TIMERn_ch2_i: output 1KHz %30 duty PWM signal pad_ADVANCED_TIMERn_ch3_i:

step 3

pad_ADVANCED_TIMERn_bkin: pad_ADVANCED_TIMERn_etr: pad_ADVANCED_TIMERn_ch1_i: pad_ADVANCED_TIMERn_ch2_i: output 1KHz %30 duty PWM signal pad_ADVANCED_TIMERn_ch3_i:

step 4

pad_ADVANCED_TIMERn_bkin: pad_ADVANCED_TIMERn_etr: pad_ADVANCED_TIMERn_ch1_i: pad_ADVANCED_TIMERn_ch2_i: pad_ADVANCED_TIMERn_ch3_i: output 1KHz %30 duty PWM signal

step 5

pad_ADVANCED_TIMERn_bkin: pad_ADVANCED_TIMERn_etr: pad_ADVANCED_TIMERn_ch1_i: pad_ADVANCED_TIMERn_ch2_i: pad_ADVANCED_TIMERn_ch3_i: output 1KHz %30 duty PWM signal

step 6

pad_ADVANCED_TIMERn_bkin: pad_ADVANCED_TIMERn_etr: pad_ADVANCED_TIMERn_ch1_i: output 1KHz %30 duty PWM signal pad_ADVANCED_TIMERn_ch2_i: pad_ADVANCED_TIMERn_ch3_i:

10.3. IO connection:

Note

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