#!/bin/bash
# adds additional digital inputs and relay outputs to the Raspberry Pi platforms
# the stock RPI Venus distribution includes two relays and two digital inputs
# adding the additional GPIO pins to /etc/venus/gpio_list
# makes additional digital inputs available
# all 5 defined digital inputs are activated by this script
#
# the Raspberry PI default is for the first 8 GPIO pins to have pull UPs
# and the remaining have pull DOWNs. This makes some digital input pins behave differently
# this script also installs a DT overlay that switches to pull UPs for all digital input pins
#
# Only the first relay can be assigned to a function: alarm, genertor start/stop or pump.
# Others are only provided manual on/off control from the menu.
# Six relays are supported. Only the first relay can be assigned to functions
# The remaining relays are manual on/off only.
# run manually initally, then called from reinstallMods
# to uninstall/deactivate, call this script with "uninstall" as first parameter
# original assignments for relays 5 and 6 create conflicts with interrypt pins
# on hat boards such as the Waveshare dual CANbus hats (regular and FD versions)
# An option in this setup script allows selection of different GPIO assignments
# for relays 5 and 6 to avoid these conflicts
#
# Because this conflict will be rare, the option is considered optional.
# That is, an automatic install WILL be permitted even if a manual install has not
# been perfomred.
#
# VeCanSetup will alert the user of conflicts and prevent installing the second
# CANbus interface until this script is rerun to move the relay assignments.
# Note, this script DOES require a system reboot.
