This repository was created to demonstrate my technical skills for the Firmware Developer role at Epitome GmbH. This repository contains two projects, "logger" and "uart_interactive_cli". Firmwares written in Bare-Metal for STs NUCLEO-F446. The projects were also evaluated on the hardware and their functionality was confirmed.
Common startup functions are located in the include/startup_stm32f446retx.s and include/system_stm32f4xx.c files to be included in all projects.
The repository includes CMSIS as submodules under lib folder. You can clone the repository, then initialize and update the submodules with git submodule init and git submodule update commands.
makefile contains necessary build scripts and compiler flags for all projects. Individual settings can be changed from local makefiles from projects such as logger makefile
Browse into any directory and run make to compile.
cd projects/logger
make
If everything is set up correctly, you should see the completed message.

- logger - Contains a pure C logging module and it streams the output through UART
- uart_interative_cli - Accepts a string from the user over UART, interprets the string as commands with arguments, and gives back the corresponding response yo the user on UART.
