  • I/O IRQ ?

    Does the Picaso GFX generate any IRQs?

    Is there a timer function that can be used to sample the input pins at a certain rate, and if so, what formula can I use for the timer value if the value isn't a ticks-per-second rate?

    Not really, you may have limited success for low res sampling is you set a timer event to call a function to monitor change on a pin and count transitions, but there is no accurate way of doing it. For instrumentation the displays are usually intended to work with some kind of 'front end' processor, so the display can be busy getting on with graphics tasks while the front end processes information.
