Spad.next doesn’t seem to recognize a long press or a press and hold of the RSG GNS530 buttons. When I was hacking around with it, it only seemed to detect the button down and button up.
So what I did was store the button down time on the button down event. I then have it send AS530_CLR_Push when the button up comes less than a second after button down, and I have it send AS530_CLR_Push_Long when the button up comes more than a second after button down. It works, but you have to lift your finger off the CLR button after holding it before the GNS530 returns to the default NAV screen. That is a bit different than how it works when you press and hold the CLR button with the mouse. I can get used to it, but my OCD makes me want to hack around with it some more to see if I can make it “just so”.
