What software is included in the OBD Experts Protocol Stack?
When you purchase the complete OBD II Protocol Stack you will receive the source code for all the OBD II protocols. The source files are written in C and organised with a layer of abstraction to the hardware specific code so that porting of the code to alternative hardware platforms is kept simple. Currently the design is built and tested using an STM32F103 high density ARM Cortex chip so all the actual calls to this chip and the STM32’s library code are provided too. On top of the stack sits a simple API that attempts to connect to one of the protocols and if successful loops through a file requesting the desired modes and PIDs from the ECU(s).
