*/
This demo is based on the GD32350R-EVAL board, it shows how to control PWM
output by using comparator output
- CMP channel0 is configured as following:
- Inverting input is internally connected to VREFINT = 1.22V
- Non Inverting input is connected to PC1
- Output is internally connected to TIMER1 OCREFCLR (output compare reference clear)
- While PC1/PC0 is lower than VREFINT (1.22V), PWM signal is displayed on PB3
- While PC1/PC0 is higher than VREFINT, PB3 is displayed in low level.
Connect PA1 to PC1.
