Firmware-73 Intro

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

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.

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.
