Introduction
The BITalino R-IoT module is the 7th generation of IRCAM's wireless sensor digitizing
unit, an essential tool linking motion sensing, gestural recognition and Live Performance
Arts.
Since 2001, IRCAM aimed to provide a low latency, high data-rate & resolution and stage
compatible devices, capable of streaming gestural information to the computer from
multiple performers.
The BITalino R-IoT embeds a 9-axis digital IMU sensor (LSM9DS1)
[1]
featuring a 3-axis
accelerometer, a 3-axis gyroscope and a 3-axis magnetometer, allowing for instance the
onboard computation of the absolute orientation of the module in space. The sensor is
attached to the SPI port to sample the 16-bit motion data at high speed.
The core of the BITalino R-IoT module is based upon the CC3200
Instruments (TI) and it is compatible with Energia
[3]
, a programming tool for TI
processors with the easiness of the Arduino

Overview
3.1.1
The CC3200 MCU
Created for the Internet of Things (IoT), the SimpleLink WiFi CC3200 device is a wireless
MCU that integrates a high-performance ARM®Cortex-M4 MCU allowing developers to
build an entire application with a single IC. With on-chip Wi-Fi, internet and robust
security protocols, no prior Wi-Fi experience is needed for faster development.
