Usage

Here's a basic example of how to use the servomotor package:

For more detailed usage instructions, please refer to the documentation.

Choosing the serial port

The command line tools work out which serial port to use in this order, highest priority first:

1. -p PORT on the command line (-P instead pops up a menu of detected ports)
2. the SERVOMOTOR_PORT environment variable
3. the port saved from the last successful run
4. an interactive menu, if none of the above apply

So a port can be set once for a whole shell session:

export SERVOMOTOR_PORT=/dev/ttyUSB0        # Linux
export SERVOMOTOR_PORT=/dev/cu.usbserial-110   # macOS
set SERVOMOTOR_PORT=COM3                   # Windows (cmd)
$env:SERVOMOTOR_PORT = "COM3"              # Windows (PowerShell)

-p still overrides it for a single command, and -P always shows the menu.

After a port is opened successfully it is remembered, in a per-user location:

Delete that file to forget the remembered port.

Serial port permissions on Linux

Serial devices usually belong to the dialout group (uucp on some distributions). If you get a permission error, add yourself to it:

sudo usermod -a -G dialout $USER

then log out and back in for the change to take effect.
