    If I set my code (assume C, and a fast computer) in a loop to issue "GPIO SET 1" and then "GPIO CLEAR 1" what is the fastest rate that the port 1 pin will be changing?

    Hi Dominic,

    Usually IOs can be toggled at a rate of a few hundred toggles per second. But the exact number can vary based on many factors, primarily with the number of devices in the topology and the traffic. We do not officially quote a number because of this possible variation, but 200 - 300 toggles per second can be expected.

    Thanks,

    Is there a limit to how many times an input can be read or an output toggled? Is this using a technology that has a cycle limit?

    Hello Curtis,

    The only limit is the number of commands that can be sent to the device per second. There is no limit specific to toggling. I have responded to your other thread with some more detail.

    Thanks,
