SPI common options

Syntax:
%C [-c config_file] [-v]

    -c config_file      Path to the SPI configuration file
                        (default: /etc/system/config/spi/spi.conf)
    -v                  Increase verbosity. This will override the "verbose" value in the config file.

Note: SPI config file template can be found at "lib/io-spi/config_files/spi-template.conf".

Examples:

# Start the driver using a custom config file path
%C -c /etc/custom/spi.conf
