Bare-metal-ARM-Cortex-M4

This project uses the Nordic Semiconductor nRF52833 DK to send messages over the UART peripheral.
This project runs bare-metal, meaning it doesn't run on an OS. It prodives accurate delays using the SysTick peripheral in ARM Cortex-M4.

Drivers included:

UART
GPIO
SysTick

Picture below shows an accurate delay of 5ms using SysTick
