- This demo is based on the GD32350R-EVAL board, it shows how to
- configure the TIMER peripheral to generate the toggle signal.
-
- The TIMxCLK frequency is set to systemcoreclock , the prescaler is 42000(GD32F330)
- or 54000(GD32F350) so the TIMER1 counter clock is 2KHz.
-
- TIMER1 configuration: output compare toggle mode:
- CH1 update rate = TIMER1 counter clock / CH1CC = 2000/4000 = 0.5 Hz.
