Worked on enhancing CAN driver stability for the hc32f460 platform within the levizh/rt-thread repository, focusing on embedded systems and microcontroller configuration using C. Addressed compatibility issues by correcting CAN peripheral references and introducing conditional compilation to disable CAN-FD features on unsupported hardware. This approach reduced build errors and improved runtime reliability for CAN communication across hc32-based boards. The work demonstrated proficiency in hardware abstraction and cross-platform driver maintenance, resulting in smoother integration and lower maintenance overhead. These targeted improvements contributed to more reliable CAN workflows, supporting industrial and automotive use-cases that depend on robust embedded driver performance.
