I have a a 50 kHz digital toggle signal which i want to count to 1.3Mio and toggle an output signal for 500ms on and then off. Would that be possible with the Machine control and the portenta? How fast can a toggle signal be for the portenta / machine control to count for stable results?
The fastest counting is when using internal timer hardware, configured to count from an input pin. That will work to megahertz or so, consult the processor data sheet for specifications.
The inputs on the machine control seem to be very slow. I only get 1 kHz or so, even with the hardware interrupts. Any help here?
