Hello World UART output using various options
-------------------------------------------------------------------------------
This is a collection of example UART communication (only in one direction).
The repeatedly transmitted data is "Hello World!\r\n", using 8n1 settings.
Logic analyzer setup
--------------------
The logic analyzer used for capturing is a ChronoVu LA8 at a sample rate
of 5MHz (for baud rates 921600 - 230400), 1MHz (for 115200 - 19200),
and 625kHz (for baud rates 9600 - 110).
The ChronoVu LA8 probes were connected to the UART like this:

GND GND

The sigrok command line used was:
sigrok-cli -d 0:samplerate=<hz> --samples 8388608 -p '1=TX' -o <file>.sr
We capture as many samples as fit into the 8MByte buffer of the logic analyzer.
