Gain practical CAN Bus skills from protocol architecture and data frames to STM32 bxCAN driver development, filtering, transceivers, and real embedded applications. Controller Area Network communication is central to many automotive and industrial systems where reliable multi-node messaging is required. This course builds CAN knowledge from protocol fundamentals through STM32-based implementation, connecting theory to hands-on embedded communication. The course covers CAN evolution, bus architecture, high and low lines, dominant and recessive states, inverted logic, arbitration, protocol layers, identifiers, RTR bits, standard and extended frames, data transmission, MCP2551 transceivers, STM32 bxCAN peripherals, development setup, generic drivers, bare-metal CAN drivers, filters, and applications. Learners practice the details that determine how CAN messages are structured, prioritized, filtered, and exchanged in real systems. This combination of protocol understanding and firmware implementation supports stronger debugging and system integration; by the end of this course, learners can develop STM32 CAN applications for embedded networks. Embedded systems engineers, automotive firmware developers, industrial automation developers, and STM32 programmers who need practical CAN Bus skills. Useful for learners working with transceivers, bxCAN, message frames, filters, arbitration, and bare-metal communication drivers. The course starts with CAN protocol concepts before introducing the physical and data-link details. Learners then connect those concepts to STM32 bxCAN and MCP2551 hardware. Driver and application sections reinforce filtering, transmission, and embedded-network behavior. This course is based on Mastering the CAN Bus from Ground Up™, by Israel Gbati.
