Bike line protocol
About the Bike line protocol PCB
Bike line protocol is an open source PCB design by c4deszes, published on GitHub. It is a 2-layer board measuring 79.5 × 50 mm, with 100 components from 41 distinct parts.
Other key parts include the TPS61085, FT4232H, MCP2003, 93LCxxC and 74HCT595. By type, the board carries 32 resistors, 31 capacitors, 11 diodes, 8 connectors, 7 ICs and 4 switches.
From the project
Serial messaging protocol
The project includes a CMake based environment that can be included as a subproject. A function call is used to instantiate the library in a way that's unique to the application.
A code generation configuration is required, a single instance multiple network definitions and multiple nodes can be used.
The library only has interface and test targets, run the C library tests using cmake --workflow --preset workflow-test.
