Over five months, Andrey Suljak developed and enhanced embedded firmware for the MacRover/maxwell repository, focusing on robust control systems and hardware integration. He built a configurable CAN testbench supporting PID parameterization and device ID standardization, and established a modular VIPER firmware architecture to enable cross-MCU development. Using C and Python, Andrey implemented multi-card support, improved state machine reliability, and refactored CAN bus communication for scalable sensor management. He addressed hardware-specific issues such as I2C multiplexer driver corrections and TMC inversion configuration, demonstrating depth in low-level driver development, embedded C, and version control while ensuring maintainable, testable, and future-ready code.

Jan 1, 2025January 2025 monthly summary for MacRover/maxwell. Focused on architectural modernization and reliability improvements to enable scalable sensor/card management. Delivered a VIPER-based port of the RAD main state machine with core CAN/EEPROM scaffolding, and resolved an I2C multiplexer driver issue to improve sensor data reliability. Key results: - VIPER Architecture Port and Core State Machine: Ported the RAD main state machine to VIPER with can.h/c and main.h, established core CAN/EEPROM handling, and laid groundwork for VIPER_CARD_READ. Commits illustrate steady progression: c45f4f24..., 7a0ede7d..., 8b3aea63..., b37dc52f..., 912b9eb2... - I2C multiplexer driver fix for TCA9544A: Corrected I2C peripheral usage from hi2c1 to hi2c2 to ensure reliable interfacing with the I2C multiplexer and sensor data wiring. Commit: 2be35e9a... - IOC CAN params and future-ready wiring: Updated IOC CAN parameters across files and initiated drivers import for VIPER_CARD_READ. Commit: b37dc52f... Overall impact and accomplishments: - Establishes a modular VIPER-based core, enabling safer future feature integration (e.g., VIPER_CARD_READ) and improved maintainability. - Improves data reliability for sensor inputs via corrected I2C wiring, reducing debugging time in downstream features. - Clear traceability through dedicated commit messages supporting performance reviews and audits. Technologies/skills demonstrated: - VIPER architecture, embedded C, CAN and EEPROM handling - I2C/multiplexer integration (TCA9544A) - Header/source architecture and data encoding/decoding utilities - Version control discipline with incremental commits and traceability

Nov 1, 2024November 2024 — MacRover/maxwell: VIPER firmware work focused on establishing a solid foundation for cross-MCU development, expanding hardware support, and improving codebase maintainability. Key outcomes include: VIPER Firmware Foundation (initial file structure, CMSIS headers, low-level drivers, and release directory), VIPER Peripheral Integration (LED indicator, CAN, UART, I2C, TIM peripherals with updated IOC and clock configuration), and Repository Cleanup (removal of duplicate HAL GPIO files). These efforts enable faster feature delivery, more reliable hardware communication, and a cleaner, scalable firmware architecture.
