SNAP Protocol Library
Simple library for sending and receiving Snap packets.
The library has the following features:
- easy to use
- collision avoidance (e.g. RS486 half-duplex networks)
- crc-16 error detection
- interrupt-based receiving
- blocking transmitting
The Snap protocol is very flexible.
The library has the following restrictions to keep it simple:
- 3 byte addresses (16.7 million nodes)
- crc-16 error detection
- command-mode bits and protocol specific flags not supported
- 2 preamble bytes to improve packet start detection
Example: the device will echo back any data received
