CMUcam Related Interrupts

phrontist · #1 31-01-2006, 22:35

Roughly how many interrupts per second does the default CMU cam code generate? What priority level are they? We're using low-priority interrupts for other sensing components, and I'm trying to estimate whether we will be generating them at a reasonable rate. I've heard rates as high as 10,000 ISRs are possible without issue, as long as the main loop and individual ISRs execute rapidly. Is this accurate?

I believe it's just over 100 per second (the number of bytes sent per second).
