testv1.0.0

Develop low-power firmware for an ESP32-based environmental sensor that reads temperature/humidity, processes data, and transmits via BLE or Wi-Fi. The solution must handle deep sleep modes and robust error recovery for battery-powered deployment.

Design a real-time motor control system using FreeRTOS on STM32, managing priority inversion and ensuring deterministic timing for PWM generation and sensor feedback. Includes fault detection and safe shutdown procedures.

Implement a BLE GATT service on a Nordic nRF52 to stream biometric data (heart rate, SpO2) with connection management and power optimization. Must handle disconnection gracefully and retry logic for packet loss.

Build a CAN-to-UART gateway on a Cortex-M MCU that filters and forwards vehicle diagnostic messages. Includes error frames detection and timeout handling to avoid bus lockups.

License reusable firmware modules (drivers, protocol stacks, RTOS configurations) to hardware OEMs. Each kit includes documented APIs and integration guides, reducing their time-to-market.

Offer in-depth firmware security audits focusing on memory safety, proper use of volatile/atomic operations, and mitigation of undefined behavior in production code. Deliverables include risk report and patched firmware.

Consult on RTOS task decomposition, priority assignment, and synchronization design to prevent priority inversion, deadlocks, and interrupt latency. Provide code reviews and architecture diagrams.
