API Reference

Complete API reference for RevPiModIO2 Python library.

Overview 

RevPiModIO provides several main classes for programming Revolution Pi hardware:

RevPiModIO - Main class for managing all devices and IOs
RevPiModIOSelected - Manage specific devices only
RevPiModIODriver - Write data to virtual device inputs
IOList - Container for accessing IOs
IOBase - Base class for all IO objects
Cycletools - Toolkit for cyclic programming
EventCallback - Event handler class

Quick Examples 

Basic Usage 

import revpimodio2

# Initialize
rpi = revpimodio2.RevPiModIO(autorefresh=True)

# Read input and control output
if rpi.io.button.value:
    rpi.io.led.value = True

# Cleanup
rpi.exit()

Cyclic Programming 

import revpimodio2

rpi = revpimodio2.RevPiModIO(autorefresh=True)

def main_cycle(ct: revpimodio2.Cycletools):
    if ct.first:
        ct.var.counter = 0

    if ct.changed(ct.io.sensor):
        ct.var.counter += 1

rpi.cycleloop(main_cycle)

Event-Driven Programming 

import revpimodio2

rpi = revpimodio2.RevPiModIO(autorefresh=True)

def on_change(ioname, iovalue):
    print(f"{ioname} = {iovalue}")

rpi.io.button.reg_event(on_change)
rpi.handlesignalend()
rpi.mainloop()
