I have an application where I need minimal digital signal processing.
Everytime the analog input crosses zere I recalculate the gain as a function of time and output a pwm d/a signal. Hmm, it would be really cool to log the signal to sdcard, too.
Can the teensies handle an 80+ KHz sample rate? (40 KHz sonar echo)
I thought I saw some a/d and pwm d/a libraries and/or examples, but I can't find any of them at the moment.
Teensy 3.0 hardware looks much more capable, but it's not clear what a/d and d/a libraries the 3.0 software currently include.
