Legal Removal Request

Post: Hi I am using an IO Pi Plus set as inputs on one bus, and currently running a test setup for what will be a larger project involving sensors, which have a detect/sense out terminal at 5v. The plan would be connect these sense outputs to the IO Pi as 5V inputs on each pin for each sensor. I would like to set it up so that IO PI is reading/polling all 16 pins indviually all the time, and print a message in the terminal window when a 5V input is detected on any of the 16 pins from any sensor. The pins need to be set up indiviually as each pin or set of say 4 pins will control differnt sets of LED's to switch them on or off depending if there is a 5V input or not. I have been trying a bit of code out (below) however not having much look, I have attempted to remove bits and add bits of code that I think may help, however nothing has worked. I have tried applying 5v input to pin 16 on Bus 2 from the senso for testing, however nothing is printed on screen, if I change != 0 to != 1 it constantly says motion detected instead. I have also tried applying the - or ground source from the 5V supply to the GND pin, however that does not work and nothing printed on screen when I apply 5V to pin 16. #!/usr/bin/env python from IOPi import IOPi import time busin = IOPi(0x24) busin.set_port_pullups(0, 0xFF) busin.set_port_pullups(1, 0xFF) busin.set_port_direction(0, 0xFF) busin.set_port_direction(1, 0xFF) busin.invert_port(0, 0xFF) busin.invert_port(1, 0xFF) busin.read_port(0) busin.read_port(1) while True: busin.read_pin(16) if (busin.read_pin(16) != 0): print("Motion detected.") Any assistance would be very much appreciated. Many Thanks Rhys
