Just connect the device and launch your application

The software interface provides all the necessary information to monitor in real time the frequency variations of the QCM in a fully automatic way. The software allows you to uniquely identify the device connected to the COM port, so you can simultaneously plug multiple devices to your PC. The experimental data can be stored in a data file for post-processing and custom analysis.

Arduino-based code the easiest way to program your device

The Teensy 3.2 development board is fully compatible with the development environment based on arduino programming language. Take advantage of the simplicity of coding and the endless resources shared by the community for programming your scientific device. Based on FreqCount library developed by Paul Stoffregen the computing capability of the 180 MHz Cortex-M4F microcontroller allows frequencies up to 65 MHz to be measured.
