The WiDig is a thumb-sized easily configurable hardware device that can encode up to 8 sensor signals to audio-visual industry compatible messages, while it can also decode such messages to control up to 8 actuators. It supports a wide variety of analog and digital sensors and actuators. It transmits and receives these messages to/from a computer or mobile device wirelessly via Bluetooth, or to a computer wired via USB cable, for analysis and/or control purposes, in real-time !

Real-time The WiDig has 8 inputs that can sample at up to almost 1000 Hz with milliseconds latency to capture even the finest gestures and movements. This real-time capability, together with its compatibility with a wide variety of sensors and actuators, makes it uniquely suited for use in interactive installations, live performance controllers, and any other setup that requires instant feedback or control.

Sensors The WiDig can be used with a wide variety of analog and digital sensors. Connect up to 8 sensors directly. Analog (0-5V) sensor input is encoded with 10 bit resolution (ie. 1024 steps of each 4.9 mV). Digital sensors, most of which have much higher resolutions, are interfaced using I²C. The firmware includes algorithms to communicate with I²C sensors and pre-process their output. It's possible to connect more digital sensors by daisy-chaining them. For hardware hackers, the WiDig features a hardware hacking area to add your own circuit.

Actuators Control different types of actuators: regular binary "on/off" actuators, PWM actuators such as RC servos, or digital (I²C) actuators. The pins configured for output can provide low current (1 mA) control signals only. To drive an actuator that requires larger currents you need to install a transistor or similar, that is controlled by the actuator output, to enable/disable power supplied to the actuator from the 5V power. The WiDig features a hardware hacking area to add your own circuit.

Wireless The WiDig can communicate wirelessly, via Bluetooth Low Energy (BLE) at the MIDI transmission speed of 31.25 Kbps. The wireless range of the WiDig is specified to be at least 10 meter (without obstructions). A Bluetooth interface allows for the use of up to 7 WiDig units simultaneously. Any BLE interface (such the built-in Bluetooth interface of Apple devices) or adapter should work. The WIDIBud automatically connects to the WiDig and appears as a MIDI port. More features to be added soon through a firmware update: Pair the WiDig with a BLE-to-MIDI cable adapter and connect directly to your MIDI gear. Communicate via Wifi with OSC messages.

Wired When enabled for communication via a USB cable, the MIDI messages appear on the computer at a virtual serial port (called "COM" port on a Windows computer) running at 115.2 Kbps, ie. much faster than the MIDI transmission speed of 31.25 Kbps.

Mobile Connect easily with your smartphone, iPhone, iPad, iPod or other mobile devices via Bluetooth Low Energy (BLE). Once configured with our software, the WiDig's MIDI messages can be used to trigger or control apps, or conversely use apps to control actuators connected to the WiDig.

Compatible The WiDig uses audio-visual industry compliant MIDI messages to encode sensor signals and control actuators. While it's compatible with analog (0-5V) sensors, it's I²C capability makes it compatible with one of the more common bi-directional digital communications protocols for both sensors and actuators. While it's easy to use with regular binary "on/off" actuators, it can also output pulse-width modulated (PWM) signals for the control of actuators such as RC servos. And you don't need a MIDI interface to receive the MIDI messages. The wireless transmission complies not only with the Bluetooth Low Energy (BLE) v4.0 standard but also with the BLE-MIDI standard, so if the WiDig is connected via Bluetooth Low Energy (BLE), its MIDI messages appear on the computer at a virtual MIDI port, whether it's on a computer or mobile device. Another feature to be added soon through a firmware update: Receive these MIDI messages using a BLE-to-MIDI cable adapter with MIDI DIN plugs, so that they are ready for use with MIDI gear. If its connected via USB, its MIDI messages appear on the computer at a virtual serial port (called "COM" port on a Windows computer), which is then mapped to a virtual MIDI port by our Connect software. The USB communication complies with the USB v2.0 standard. Our software provides compatibility with other standards such as Open Sound Control (OSC) and Internet of Things (IoT) webhooks.

Configurable It's updateable firmware v8.0x, configurable with our software, enables it to operate in both "standalone" mode (sensor data is processed before it is transmitted) as well as host mode (raw sensor data is transmitted). Standalone mode includes various sensor processing and mapping features such as gesture recognition that can be conveniently configured using our EditorX software. Configure it with EditorX and it will remember the settings after power down. Our EditorX software allows you to configure the WiDig to map the data in a variety of ways for use with the software or device of your choice. Once configured using our EditorX software you can use the WiDig with software that communicates directly with devices through the virtual MIDI port or virtual serial port. If you need raw sensor data or if you need more sensor mapping or analysis complexity, use it in host mode with our Link software or in combination with a programming or analysis environment to process the sensor data. Or you can just use our Connect application to map the data to/from the serial port from/to a virtual MIDI port or an OSC port. For Internet of Things (IoT) applications, our Connect software includes mapping to a webhook.
