A Cayenne LPP library written in C

This library provides functions for generating Cayenne LPP compatible payload. For example, the generated payloads can be used with LoRaWAN devices.

This library is adapted from the C++ version from MBED.

See the Cayenne LPP format documentation for details on the payload format.
