simply run the application for QCM frequency monitoring

The software provides a graphical interface that automatically displays real-time QCM frequency changes, ensuring accurate and consistent measurements with integrated temperature monitoring. Experimental data can be saved in a data file for later post-processing and customized analysis. The software also enables unique identification of devices connected to COM ports, allowing for the simultaneous connection of multiple devices to your PC.

The Teensy development board is fully compatible with Arduino programming language and environement. 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. 


Download the comprehensive set of open-source software, firmware, and source code for your OpenQCM Wi2 device, enhancing your research experience. The open-source approach promotes collaboration by encouraging users to develop, modify, and share their code, ultimately fostering an innovative and collaborative environment.
