This is a C++ library implementation of OCPP for version 1.6, 2.0.1 and 2.1. (see OCPP protocols at OCA website). The OCPP2.0.1 implementation of libocpp has been certified by the OCA for multiple hardware platforms.
Libocpp's approach to implementing the OCPP protocol is to address as much functional requirements as possible as part of the library. Since OCPP is a protocol that affects, controls, and monitors many areas of a charging station's operation this library needs to be integrated with your charging station firmware.
This library is integrated within the OCPP and OCPP201 module within everest-core - the complete software stack for your charging station. It is recommended to use EVerest together with this OCPP implementation.
Check out the Getting Started guide. It should be you starting point if you want to integrate this library with your charging station firmware.
See the COMMUNITY.md and CONTRIBUTING.md of the EVerest project to get involved.
OCPP1.6 is fully implemented.
