how to read the value come from X2 connector of RevPi Connect

[Wang]

hello,
Our customer would like to use python program to read the external signal from X2 connector, is there any manual and sample code on it?
Many thanks in advance!

Hello Wang create a pictory configuration. Then have a look at this tutorial:
https://revolution.kunbus.com/tutorials ... n-connect/
Bit 6 of the RevPiStatus variable in the process image contains 0 or 1, depending on whether 0V or 24V are applied to the input.
In theory it works like that:

Code: Select all

pi@RevPi:~ $ piTest -r RevPiStatus
1 Byte-Value of RevPiStatus: 1 dez (=01 hex)
1 Byte-Value of RevPiStatus: 65 dez (=41 hex)

Here an example implementation:

Code: Select all

#!/usr/bin/env python3
# CheckConnectInput.py
# Check the digital input pin of RevPi Connect

import revpimodio2
import time

rpi = revpimodio2.RevPiModIO(autorefresh=True)

while True:
	if rpi.io.RevPiStatus.value & (1 << 6):
		print('Hi')
	else:
		print('Lo')
	time.sleep(1)
