Qt Creator

Boot to Qt, Immediate Start with Software Stack

1. Install Qt for Device Creation• Select your hardware, flash your device with

Boot to Qt• Full Qt-optimized software stack, Yocto-

based• Full tool chains, pre-integrated into Qt

Creator2. Write your Software in Qt Creator

3. Deploy with single click• On-device debugging

You can run your software on a real embedded device

immediately!

Connectivity with Qt, within an IoT System

• Multiple non-GUI, connectivity-related modules, eg.• Qt Networking (HTTP, TCP/UDP, SSL)

• Qt Bluetooth (and Bluetooth LE)

• Qt SerialPort

• Qt SerialBus (coming in Qt 5.6)

• Qt NFC

• Easy to mix Qt and native C/C++ code for HW connection

Qt and Big Data

• Big Data scalability is usually an issue of backend systems• Cloud computing

• For data visualization and handling, Qt libraries are often used with large data sets• Visualization industries

• Research institutes

• Full C++ performance

• When you write your applications and backends, you should be prepared for large data sets as well

Extendibility, in IoT context

• Future platforms

• New sensor HW

• New sensor protocols / communication mechanisms

• Additional system connections / backend systems

• As systems can be deployed everywhere, extreme flexibility is needed from the system architecture design for long lifespan

Future-proofing with Qt

• For future platforms or platform versions, Qt as a cross-platform framework future-prooves your software to run there without changes

• For new HW Qt provides plugin-based APIs that are easy to extend
