Enough already of all this theory … it’s time to put the CAN bus into practice. Since my goal is not just to get CAN working, but also to fully explain how it can be implemented on an STM32 µC, I will present the following material in two sections: a description of the API, as defined in the JeeH library and a detailed walkthrough of the entire driver.
This driver is written in C++ with templates, and is very compact (under 80 lines of code).
