Hi,
I have a question regarding the possible sampling rate of the ADW of the Teensy 4.1.
Is it possible to sample the ADW with 100k Hz or even better 200k Hz?
I want to build a measuring device to measure the muzzle velocity of a 6mm steel ball, which is accelerated with compressed air. For this purpose, two photodiodes are to be mounted in the barrel at a distance of 150mm. The targeted velocity is 80m/s.
If I have calculated correctly, a 6mm steel ball results in an overlap time of 7.5µs per sensor. So I would have to sample somewhere in the range of 200k Hz to be able to make a reliable statement.
I would like to use the Teensyduino programming interface.
Is this possible with the teensy 4.1?
I found an old thread talking about the sampling rate of the ADW on a Teensy 3.1, but there it is about the audio library and 44.1kHz

Thanks
