I will develop embedded firmware for stm32 arm microcontrollers

Need embedded firmware development? I'm a senior embedded systems engineer with real product development experience in industrial measurement instruments.

I don't just write demo code I write production firmware that runs reliably in the field. My products are deployed in power industry applications where reliability is critical.

What I can help with:

- STM32 / ARM Cortex-M firmware development

- Sensor data acquisition & processing

- Communication protocols: UART, SPI, I2C, CAN, Modbus

- Low-power design optimization

- Peripheral driver development

- RTOS integration (FreeRTOS)

- Custom PCB communication testing

- Firmware debugging & optimization

My background:

- Developed commercial high-voltage measurement instruments

- 30+ years in embedded systems

- Deep understanding of industrial reliability requirements

- Experience with precision analog signal processing

What I need from you:

- MCU part number and development board info

- Schematic or pin assignments

- Functional requirements description

- Any existing codebase (if applicable)
