Hello there,
I have worked on many Microcontroller platforms. My expertise includes microcontrollers like ESP32, ATMega328p, FRDM-KL25Z freedom board(NXP) and many more evaluation boards. I have done bare-metal coding for FRDM_KL25Z board and I have one of the board right on my workbench.
So, please give me a try and I promise you'll be worthy of what you pay me. Thanks
