Use STM32 platform, install FreeRTOS, implement UART CLI for next functionality: - light on LED for specified period in seconds, other commands are available while LED is ON. When after specified period led is off - notify user with text message on same console - set/get brightness for LED - return state of user button - enable/disable button monitoring, asynchronously monitor state of button and if it's state changed(pressed/unpressed) notify user with text message on same console - help CLI must be user friendly as much as possible. Result: you can connect device to PC and work with CLI
