Under Jiehui's help , I can able to get DC value from PA1 pin . Under this case , I still have some problem in getting AC value . Below is the result from getting AC value by PA1 pin . The AC value output is 60Hz and 3V . I know , the value is not right ,because getting value not under the high level . Is there any example I can follow ? Or how can I set in SensorPIR demo .
