Jacdac for .NET

Jacdac is a plug-and-play hardware/software stack for microcontrollers and their peripherals (sensors/actuators), with applications to rapid prototyping, making, and physical computing.

This repository contains .NET Core (5+), .NET nanoframework and TinyCLR client libraries for the Jacdac protocol, as well as transports over USB, SPI, WebSockets.

Assemblies

The Jacdac project contains C# sources of the Jacdac protocol for various .NET runtime, including desktop or TinyClR. To avoid mscorlib issues, each platform recompiles these sources into its own assembly where C# files are simply shared as links. As a result, the C# used in the Jacdac project is .NET 5+/.NET nanoframework/TinyCLR compatible (and also inherits limitations thereof).

.NET Core and .NET IoT Core

• Jacdac.NET, core runtime
• Jacdac.NET.Clients, service clients
• Jacdac.NET.Transports.Spi, SPI transport layer for SPI Jacdapter using .NET IoT
• Jacdac.NET.Transports.WebSockets, WebSocket transport
• Jacdac.NET.Transports.Hf2, HF2 protocol layer, .NET5
• Jacdac.NET.Transports.Usb, Usb transport, .NET5 (not functional, experimental)

TinyCLR

• Jacdac.TinyCLR, mirror of Jacdac library and UART transport
• Jacdac.TinyCLR.Clients, service clients
• Jacdac.TinyCLR.Storage, SD card storage support

.NET nanoframework

Under development: we need help to either write a native single wire serial transport... or build a SPI HAT for Feather S2.

• Jacdac.Nano, mirror of Jacdac library and UART transport
• Jacdac.Nano.Transports.Spi, SPI transport layer for SPI Jacdapter using .NET nanoframework
• Jacdac.Nano.Clients, service clients

Sample sources

The samples are mostly foud in ./Jacdac/Samples and cross-compiled into these projects:

• Jacdac.NET.Playground, change the command line argument to match the sample type name
• Jacdac.TinyCLR.Playground, change the sample type name in Program.cs

Misc:

• Jacdac.DevTools, a .NET Core web site/proxy to help with developing Jacdac applications
• Jacdac.Tests, unit tests, .NET6
• Jacdac, C# Jacdac sources. This package serves as a placeholder for C# files and and is not referenced anywhere. For development purposes only.

DevTools

Launch Jacdac.DevTools and use the WebSocket transport to connect your Jacdac bus to a local dashboard. This allows you to test your code against simulators and physical devices, and leverage the tooling available in the Jacdac network.

To installm,

dotnet tool install jacdac.devtools

To run,

jacdac.devtools

Add spi on Raspberry Pi to also connect to the JacHAT

Developer setup

The rest of this page is for developers of the jacdac-dotnet library. For user documentation, go to https://microsoft.github.io/jacdac-docs/clients/dotnet.

• clone this repository and pull all submodules

git clone https://github.com/microsoft/jacdac-dotnet git submodule update --init --recursive git pull

• Restore Nuget packages. (Either in your preferred IDE/Editor or using dotnet restore).
• Execute the desired tool or build the core library using your IDE or dotnet build/dotnet run

Testing with .NET and Jacdac development server

• install NodeJS 14+
• install Jacdac cli

npm install -g jacdac-cli

• launch Jacdac dev tools

jacdac devtools

• start running or debugging Jacdac.NET.Playground. The webdashboard will serve as a connector to the hardware.

.NET IoT Raspberry Pi

• Open bash

sh ./publish.sh

• From a SSH session

cd dotnet dotnet Jacdac.NET.Playground spi
