- This demo is based on the GD32350R-EVAL board, it shows how to make an analog
- watchdog by using comparator
- peripherals in window mode:
- - The upper threshold is set to VREFINT = 1.22V
- - The lower threshold is set to VREFINT / 2 = 1.22V = 0.610V
- - The input voltage is configured to be connected to PC1
- If the input voltage is above the higher threshold, LED1 and LED3 are turned on.
- If the input voltage is under the lower threshold, LED2 and LED4 are turned on.
- If the input voltage is within the thresholds, the MCU remains in deepsleep mode
- and all leds are turned off.
- Connect PA1 to PC1.
