PJON v7.0¶
PJON™ (Padded Jittering Operative Network) is an Arduino compatible, multi-master, multi-media communications bus system. It proposes a Standard, it is designed as a framework and implements a totally software-emulated network protocol stack. 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 strategies inclusion (for memory optimization)
- 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
