Ezairo® 7111 V2 Pre Suite Getting Started Guide

3.2.1  Additional Sound Designer Software Features, Locations, and Installation

3.2.1.1  Documentation

Once the Sound Designer Software has been installed, you also have access to all the detailed technical 

documentation, such as the 

Ezairo 7111 V2 Firmware Bundle User’s Guide

 and the 

Ezairo Sound Designer Software 

User’s Guide

. See the Documentation directory under the SD installation directory; and the Firmware Bundle 

documentation is also located in the SDK documentation folder. This documentation is not required at this stage, but is 
useful for more advanced device configuration.

3.2.1.2  Sample Code

As part of the Sound Designer Software Development Kit (SDK), you have access to an archive containing sample 

code for all operation systems supported by the Sound Designer Software API. Table 4 shows the types of code samples 
available and where to find them in the archive.

3.2.1.3  iOS and Android App Development Tools

Unzipping the Sound Designer Software Development Kit (SDK) gives you access to frameworks and libraries for 

developing iOS and Android apps, as described below in Table 5.

More details on the Sound Designer SDK and its features can be found in the 

SDK Readme.html

 file, located at the 

top level of the main 

.ZIP

 file.

3.3  Configuring the Hybrid Demonstrator Board

Before connecting the Ezairo 7111 Hybrid Demonstrator Board to the programming box, ensure that a functioning 

Ezairo 7111 hybrid is installed. Refer to the 

Ezairo 7111 Hybrid Demo Board User’s Manual

 (EVBUM2533) for 

detailed instructions on how to install the hybrid. Once the hybrid is installed, ensure that the jumpers and power switch 
are configured as listed in Table 6. Full information on the jumper settings and other board options can be found in the 

Ezairo 7111 Hybrid Demo Board User’s Manual

 (EVBUM2533).
