PJON_ASK

PJON_ASK v1.0 stable

Warning: Obsolete codebase, PJON_ASK has been integrated in the PJON repository, see OverSampling

PJON_ASK was an early implementation of the PJON Standard, designed to be compatible with noisy and unreliable media like cheap 315/433Mhz ASK/FSK/OOK radio transceivers.

What is PJON?

PJON (Padded Jittering Operative Network) is an Arduino compatible, multi-master, multi-media communications bus system. It proposes a Standard and it is designed as a framework for digital communication. It is a valid alternative to i2c, 1-Wire, Serial and other Arduino compatible protocols. If you are interested to know more about the PJON Standard, visit the Wiki. If you need help see the documentation or if something is not working visit the Troubleshooting page. If you own a Saleae Logic Analyzer see saleae-pjon-protocol-analyzer crafted by Andrew Grande.

Features

  • Device id implementation to enable univocal communication up to 254 devices
  • Bus id implementation to optionally enable shared medium communication
  • Multi media compatibility (wires up to 50m, radio up to 5km)
  • Physical layer abstraction
  • 2 pin compatibility to enable twisted pair / radio modules
  • Optional auto-addressing with id collision avoidance (experimental)
  • CRC8 table-less cyclic redundancy check implementation
  • Acknowledgement of correct packet sending
  • Collision avoidance to enable multi-master capability
  • Broadcast functionality to contact all connected devices
  • Packet manager to track and retransmit a failed packet sending in background
  • Error handling
