This demo is based on the GD32150R-EVAL/GD32190R-EVAL board, it shows how to
|
||||
configure the TIMER peripheral in PWM (Pulse Width Modulation) mode.
|
||||
|
||||
The TIMxCLK frequency is set to systemcoreclock (72MHz), the prescaler is 72
|
||||
so the TIMER1 counter clock is 1MHz.
|
||||
|
||||
TIMER1 Channel1 duty cycle = (4000/ 16000)* 100 = 25%.
|
||||
TIMER1 Channel2 duty cycle = (8000/ 16000)* 100 = 50%.
|
||||
TIMER1 Channel3 duty cycle = (12000/ 16000)* 100 = 75%.
|
||||
|
||||
Connect the TIMER1 pins to an oscilloscope to monitor the different waveforms:
|
||||
- TIMER1_CH1 pin (PB3)
|
||||
- TIMER1_CH2 pin (PB10)
|
||||
- TIMER1_CH3 pin (PB11)
