Installation

1. Install VA Smalltalk 11.0.1 or newer.
2. Install Tonel support in your development image following this guide.
3. Clone this repository.
4. The easiest and recommended approach is to install it via a script:

| loader path |
path := (CfsPath named: '<insert path to root pigpio-vast local repo here>').
loader := TonelLoader readFromPath: path.
loader
	beUnattended; "do not prompt and use all defaults"
	useGitVersion.
loader loadAllMapsWithRequiredMaps.

Or you can load the Configuration Map RaspberryHardwareInterfaceCore from the context menu of the Configuration Maps Browser: "Import" -> "Load Configuration Maps from Tonel repository..." -> select path to root pigpio-vast local repo. This will open a dialog and will use convenient defaults for the load. Refer to its documentation for more details.

5. Optionally run the SUnit tests included in the map RaspberryHardwareInterfaceTest to ensure correct installation. One easy way is to right-click on the RaspberryHardwareInterfaceTest map name in the Name pane (as opposed to version pane ) and then select Test Loaded Applications.
