ultrasonic antifouling

[gypsylyon]

Hi.

I was thinking of using Raspi to do a multi-channel ultrasound antifouling.
The problem is that with python you can't be over 20kHz, to achieve this you have to program in C.
As I suppose that you know, an ultrasound antifouling uses frequencies up to 40 kHhz.
Now I'm learning the libraries in C to do a test program.

Greetings


I have transducers 40khz and 25khz, so yes python will be too slow 

"multi channel" you mean several transducers?
What will you use for the power stage?


In principle, each GPIO can serve as a channel for each ultrasonic transducer. All you have to do is program the schirps. The power amplifier, I would build it as the Kit that Jaycar sells, through a transformer with a mosfet.
