Hello, UART

Welcome to OhmWork! This is your first challenge.

Your task is simple: make the microcontroller print "Hello, World!" to the UART. The UART helper functions are already written for you. Just call them in main() to initialize the peripheral and send the string.

Output is matched exactly, so end the line with a newline character (\n).

Key concepts:

• Memory-mapped I/O
• Polling for peripheral readiness
• UART transmit basics
