I will stm32 nordic esp32 firmware development with drivers

I will develop reliable embedded firmware for STM32, Nordic (nRF), and ESP32 microcontrollers, including custom peripheral drivers.

With 3 years of hands-on experience in industrial IoT devices and smart home products, I can help you with:

- Custom firmware for STM32, Nordic, and ESP32

- Peripheral drivers: UART, SPI, I2C, ADC, PWM, GPIO, BLE, WiFi, etc.

- IoT and industrial control projects

- Code optimization, debugging, and clear documentation

You will receive clean, well-commented source code that is easy to maintain and integrate, along with clear instructions and support.

Please message me before ordering with your chip model, required peripherals, and project details so I can confirm the scope and timeline.
