This demo is based on the GD32150R-EVAL/GD32190R-EVAL board, it shows how to
|
|
configure the comparator trigger interrupt using an external interrupt line.
|
|
In this demo,input 3.3V(GD32150R) or 5V(GD32190R)to PA1, EXTI line 21 is
|
|
configured to generate an interrupt on rising edge of the output signal. After
|
|
system start-up, enable comparator and trigger interrupt, then LED2 is on.
|
|
|
|
Connect PA1 to +3V3 or +5V.
