Idf Uart Hello World

I use UART1 to send "Hello, World!" in an infinite loop, to read it with an external UART adapter, I configured it to use GPIO7 for tx and GPIO6 for rx.

Before you can start

You need esp-idf setted up for this to work.

If you have it already all you need to do is setting the correct target. For example:

idf.py set-target esp32c3

and then you can build it using idf.py.build

For further information look at the official ESP32 Getting Started Guide
