Embedded:

I am developing embedded firmware and control architecture for DDS-240, a distributed MedTech biochemical analyzer based on STM32H723 / STM32H7 Conductor and STM32F103C8T6 / STM32F1 Executor boards.

Technical scope:

- Distributed architecture: Host → STM32H723 Conductor → STM32F103 Executor nodes.
- Firmware stack: STM32CubeIDE, STM32CubeMX, STM32 HAL, CMSIS, FreeRTOS / CMSIS-RTOS v2.
- Communication: CAN / bxCAN, 29-bit Extended CAN ID, 1 Mbit/s bus, strict DLC=8 frames, UART / USART, One-Wire.
- Peripherals: GPIO, EXTI, TIM/PWM, RTC, IWDG, Flash memory services, SWD debug.
- Device control: TMC2209 UART stepper drivers, STEP/DIR/EN motor control, pump outputs, valve outputs, thermoregulation outputs.
- Sensors: One-Wire temperature sensors, liquid level sensors, position sensors, digital/analog IO.
- RTOS design: tasks, queues, thread flags, interrupt-driven CAN RX/TX, watchdog supervisor, heartbeat monitoring.
- Protocol design: DDS-240 command stack, Host API, Conductor recipe execution, atomic Executor commands, device mapping, ACK/DATA/DONE/NACK lifecycle.
- Safety and reliability: safe-state hooks, Error_Handler, HardFault/NMI fault paths, IWDG recovery, fault-injection, reset recovery.
- Diagnostics and validation: F007 GET_STATUS, CAN counters, queue overflow tracking, HAL/ESR error snapshots, SocketCAN, candump/cansend, no-load bench tests.
