QE :Tools for Particular Applications
We are currently developing a range of Quick and Effective Tool Solutions (QE) as development tools for particular applications. The intention is greater efficiency than existing tools for our development environments. Have you ever wondered "What's the matter with this thing? I understand the development environment, and have pulled the application together, but it still doesn't go!"? We are adding development features for various particular applications to the existing debugging features of our integrated development environments. As they appear, try our new development tools if you are having problems in developing embedded applications.
- The GUI makes it easy for even a beginner to develop touch user interfaces
>> QE for Capacitive Touch - Easily and quickly tests the communications features of Renesas Bluetooth® Low Energy MCUs.
>> QE for BLE - Eases the debugging of USB systems.
>> QE for USB - Measuring current drawn by systems as a whole.
>> QE for Current Consumption
