This project is designed for anyone wanting to access GPIOs of a Raspberry Pi and starting with IoT. The library provides not just pulling up and down pins but also many of the most important protocols such as 1-Wire, I2C, SPI, etc.

## Installation
1. Install [VA Smalltalk 11.0.1 or newer](https://www.instantiations.com/products/vasmalltalk/download.html).
2. Install Tonel support in your development image following [this guide](https://github.com/vasmalltalk/tonel-vast#installation).
3. Clone this repository.
4. The easiest and recommended approach is to install it via a script:
```smalltalk
| 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](https://github.com/instantiations/tonel-vast#using-gui-menus) 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`.
