This guide focuses on integrating and porting CHPP to your desired platform. For implementation details please refer to the included README.md instead. The minimum typical steps are provided.
Implement the platform-specific functionality utilized by CHPP. These can be found in chpp/platform and include:
Sample Linux implementations are provided.
The APIs that are needed to tie CHPP to the serial port are as follows. Details are provided in link.h.
In addition, the system must implement and initialize the platform-specific linkParams data structure as part of platform_link.h
In order to initialize CHPP, it is necessary to
Several unit tests are provided in transport_test.c. In addition, loopback functionality is already implemented in CHPP, and can be used for testing. For details on crafting a loopback datagram, please refer to README.md and the transport layer unit tests (transport_test.c).
In order to terminate CHPP's main transport layer thread, it is necessary to
CHPP provides several predefined services (including Loopback Test, Service Discovery), as well as three standard services that follow the CHRE PAL API to simplify integration and testing. CHPP allows for custom services as well, as described in README.md. The standard services included in CHPP are
In order to integrate the standard services using the CHRE PAL API, please refer to each service's interface as provided in include/chre/pal/
