During January 2025, work focused on enhancing the MacRover/maxwell repository by developing robust firmware features for current sensing using the INA238 device. This involved implementing real-time current readout with comprehensive error handling and enabling persistent device configuration over I2C, ensuring settings are retained across restarts. The developer initialized and configured three INA238 sensors, each with dedicated I2C handlers, addresses, and shunt values, supporting reliable multi-device operation. Additionally, a critical bug fix addressed I2C read byte order, preventing data misinterpretation and corruption. All features were developed in C, leveraging expertise in driver development, embedded systems, and I2C communication protocols.
