Worked on the embedded-purdue/slayterHIL repository to develop an I2C-based sensor emulation framework and an IMU emulator, enabling hardware-in-the-loop testing without physical sensors. Leveraged C and device tree configuration to implement target initialization, configuration flags, and driver scaffolding, simulating gyro data, Euler angles, and linear acceleration over I2C. Enhanced motor control by introducing new PWM variables and timers, improving responsiveness and control loop timing. Refined hardware interface management by adjusting and later simplifying I2C4 overlay usage, reducing configuration complexity. Focused on embedded systems, sensor integration, and real-time operating systems, with attention to maintainability and streamlined concurrency.

Apr 1, 2026April 2026 monthly summary for embedded-purdue/slayterHIL. Key features delivered include motor control improvements with new PWM variables and timers, and refinements to the I2C4 overlay usage. The overlay work progressed through adding an I2C4 alias (commit 3cdb22fd3c6201613fa5fa3818af0f58503909f2) and ultimately removing the I2C4 configuration to simplify the hardware interface (commit ea23da28345aaf3fc1cb344d4805fa00f3981e26). The initial groundwork also included removal of mutex-related code from the imu_emulator (commit ac1e08b3b9fae5bf5a6eb67a0bac8a4caf83c16a). Major bugs fixed/cleanup included simplifying concurrency in the imu_emulator and eliminating potential hardware-interface confusion by removing the I2C4 configuration path. These changes reduce surface area for misconfiguration and improve maintainability. Overall impact and accomplishments: Faster, more predictable motor control loops; a cleaner, more maintainable hardware interface with reduced configuration risk; and a clearer path for future enhancements in motor control and overlay management. This work demonstrates solid embedded C, PWM/timer control, I2C overlay handling, and code hygiene practices.
