Firmware-73 Intro

The USB-microDig is a thumb-sized hardware input / output device - it can acquire sensor data and output control data for actuators.

It can encode analog voltage signals, such as generated by sensors, to music 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 USB-microDig to your software application.

The firmware of the USB-microDig 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 USB-microDig firmware v7.3. The firmware version number can be obtained by sending a DUMP VERSION command to the USB-microDig. If your USB-microDig’s firmware is older than v7.3 you can most likely upgrade it to v7.3 using our software, freely available from I-CubeX.com.

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