PJON

PJON v6.2

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. Visit the Wiki, Documentation and Troubleshooting wiki pages to know more about the PJON Standard.

Features

  • Configurable 2 level addressing (device and bus id) for scalable applications
  • Multi-media support with the data link layer abstraction or Strategy framework
  • Configurable 1 or 2 bytes packet length (max 255 or 65535 bytes)
  • Master-slave or multi-master dynamic addressing
  • Configurable synchronous and/or asynchronous acknowledgement of correct packet sending
  • Collision avoidance to enable multi-master capability
  • Selectable CRC8 or CRC32 table-less cyclic redundancy check
  • Packet manager to handle, track and if necessary retransmit a packet sending in background
  • Optional ordered packet sending
  • Error handling
