ArduinoIO_plugin

A MADS agent using https://github.com/pbosetti/ArduinoDriver for zero-programming Arduino I/O.

ArduinoDriver provides both a firmware for most Arduino boards and a user land C++20 driver (plus CLI commands) for directly tapping into I/O pins (including analog and PWM and DAC) via USB interface rather than through Serial Port. This allows to select pins and operations from mads.ini plugin settings, and also exploiting higher rates of USB ports wrt serials.

This is a Source plugin for MADS.

Required MADS version: 2.4.3.

Supported platforms

Currently, the supported platforms are:

• Linux
• MacOS
• Windows

Boards

Look at https://github.com/pbosetti/ArduinoDriver for supported boards. The plugin is expected to work with all boards supported by ArduinoDriver.

In the library manager of Arduino IDE, search for "UsbIo" and install it. Then, upload the firmware to your board:

#include <UsbIo.h>

void setup() {
  UsbIo.begin();
}

void loop() {
  UsbIo.poll();
}

Installation

Linux and MacOS:

cmake -Bbuild -DCMAKE_INSTALL_PREFIX="$(mads -p)"
cmake --build build -j4
sudo cmake --install build

Windows:

cmake -Bbuild -DCMAKE_INSTALL_PREFIX="$(mads -p)"
cmake --build build --config Release
cmake --install build --config Release

INI settings

The plugin supports the following settings in the INI file:

[arduinousb_source]
period = 100
pin_modes = {"1"="PULLDOWN", "2"="PULLDOWN", "3"="PULLUP", "15"="ANALOG"}

[arduinousb_sink]
pin_modes = {"1"="OUTPUT", "2"="OUTPUT", "4"="PWM"}

All settings are optional; if omitted, the default values are used.

NOTE: currently, the plugin connects to the first available Arduino board found on the USB bus. In future releases, it will be possible to select a specific board by its serial number. if you install the plugin (cmake --install build), it also installs the arduin0-io command line utility, which can be used to test the plugin and to check the connected board. Just type arduin0-io to see the available commands.
