This directory has files for the Hermes-Lite project versions 1 and 2.
Please perform all configuration with the Config screens in Quisk.
To start, go to Config/Radios and add a new radio with the general type "Hermes".
Quisk fully supports the Hermes-Lite project. But you may need a custom Widget or
Hardware file for special purposes. If you create these custom files, enter their
location (path) on the Config/radio/Hardware screen. Do not modify the files supplied
by Quisk, as these will be replaced with each new release.
# This is an example of a custom Widgets file. It changes the power calculations
# to that required by an external power bridge. Any methods (functions) defined here are used
# instead of the usual versions. See the original quisk_widgets.py to see what is available
# for replacement.

# This replaces the default version. You must alter the code to calculate watts for your
# external power meter that is connected to the Hermes-Lite power ADC.

# volts = m * code + b # The N2ADR power circuit is linear in voltage
