Hi everyone, I am working on a project about measuring high frequency of quartz crystal microbalance (QCM). I found an opensource for QCM, which is OpenQCM. They use FreqCount library comes from https://www.pjrc.com/teensy/td_libs_FreqCount.html. I have tried it, and it can work well on Arduino UNO and Mega2560 boards. However, I am trying to use it on Arduino DUE which is more accurate than UNO and Mega2560, but it does not work. I do not know why. Who can explain that? One more question, I find UNO and Mega2560 have the specific pin for frequency measurement input, 5 and 47, respectively. Who knows which specific pin for DUE frequency measurement if using the FreqCount library? I hope someone can give me a big favor.
Thank you so much
Dan
