I need to accurately measure frequency from a pressure transducer, and make it available on a LAN. A BBB ought to be able to do this, if the PRU can be made to accurately measure the frequency.
The frequency range is 30 kHz to 42 kHz. I need better than 0.01% accuracy. Overall latency in the reading is not too much of an issue, so long as it's not more than a few seconds. Does the PRU let me connect a GPIO to a counter internally? I can measure some cycles and compare that to a crystal-driven counter. Has anyone done this?
