Firmware-800 Intro

The WiDig is a thumb-sized hardware input / output device - it can acquire sensor data and output control data for actuators, wirelessly via Bluetooth Low Energy (BLE) or wired via the Universal Serial Bus (USB).

It can encode analog voltage signals, such as generated by sensors, to audio-visual industry compliant MIDI messages with high resolution. It includes 8 digital outputs, ie. the top (4th) row on the input / output connector, that can be used to control binary actuators. The input / output slots can also be configured to communicate using I2C with both sensors as well as actuators. I2C sensors are represented as 8 virtual sensor inputs, each with its own processing and MIDI mapping.

Use any of our many free software tools to interface the WiDig to your software application.

The firmware of the WiDig enables it to operate in both stand-alone mode (sensor data is processed before it is transmitted) as well as host mode (raw sensor data is transmitted). Stand-alone mode includes various sensor processing and mapping, as well as actuator control features that can be conveniently configured using our free configuration software.

Documentation

This documentation describes the WiDig firmware v8.0. The firmware version number can be obtained by sending a DUMP VERSION command to the WiDig.

This specification is divided into general, stand-alone mode and dual mode sections addressing programming commands as understood by the WiDig and transmitted messages as sent by the WiDig.
