I have some ambitions for the teensy 4.0 or 4.1. I want to create an ultrasonic driver that will attenuate and send a signal two two PZTs, such that the frequency is adjusted up for one and down for the other. The teensy would drive two circuits, one for each PZT and would keep the signal in phase and in tune. The teensy will manage two amplifiers and two resonant 'tank' circuits, each with with a fixed (but manually adjustable) inductor and a switched capacitor bank also controlled by the teensy to keep the circuit tuned as well.
Where should I start? I have access to test equipment of all kinds at Uni.
