Kevin Liang
Kevin Liang developed an end-to-end wheel speed sensing feature for the UWaterloo-Formula-Electric/firmware repository, integrating a Hall effect sensor to provide real-time speed telemetry for vehicle control systems. He implemented GPIO external interrupt handling and timer-based encoder input in C, leveraging embedded systems and RTOS skills to process sensor data and compute RPM and KMH. The solution included a dedicated real-time task for speed calculation and transmission over the CAN bus, with updates to CAN DBC definitions and project configuration files. This work established a reliable data path from sensor input to CAN communication, supporting enhanced traction control and telemetry.
