The OpenPAYGO Token is an open source token system to enable PAYGO functionality in new products.

OpenPAYGO Token v2 - Hardware Examples Repository

This project is supported by the EnAccess Foundation (https://enaccess.org/)

Neutral C Implentation of OPAYGO

This implementation is meant to be easy to port to other devices. It also includes a "unix_device" folder that shows an example of the implementation for the Unix platform as a CLI tool. To port it to another device, simply implement the functions found in that UNIX example (BlinkRedLED, GetPressedKey, etc.) for your target system and replace the import.

Arduino Firmware Implementation

This implementation with 3 different input modes (IR Remote, Membrane Keypad, USB Keypad) and supports factory setup via UART.

A small tool is also provided for the factory setup.

Tutorial on how to add to a simple product

These tutorials are based on the Arduino firmware implementation show how to wire a full product.

NOTE

If you have pulled or downloaded this implementation before the official OpenPAYGO Token release on the 10th of October 2019, please make sure to update to the latest version before using in production.
