I have knowledge and experience in firmware development for ARM Cortex based microcontroller, especially with STM32 family (from STMicroelectronics). I have experience in building driver for external peripherals, using I2C and SPI serial communication protocols.
During my work experience I lern how to design and realize hardware needed for testing firmware, I have knowledge and pratical experience how to design analog and digital filter. I have also experience in FPGA design for different clients, filter, serial interface communication and modulators.
