| # 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. | ||
