I will develop stm32 bare metal firmware and peripheral drivers in embedded c

I build reliable bare-metal firmware and peripheral drivers for STM32 microcontrollers.

I work full time as an embedded systems engineer on STM32 firmware, and I write drivers the way production code should be written: register-level, readable and documented.

WHAT I CAN BUILD

I2C, SPI, UART, ADC, DAC, timer and GPIO drivers

Interrupt and DMA based data handling

External IC drivers (RTC, DAC, EEPROM, sensors, IO expanders)

Modbus and RS-485 communication

FreeRTOS task integration

Fixing drivers that only half work

HOW IT WORKS

Send me your MCU part number, schematic or datasheet and what the driver must do. You get clean commented C source with a clear header API, a demo main.c showing how to call it, and usage notes.

WHAT YOU GET

Full source code, yours to keep

Builds in STM32CubeIDE or your toolchain

Honest answers about what is and isn't possible

I work with STM32F, G, H and L families.

Not sure your project fits? Message me first and I'll tell you honestly whether I can help.
