Hi Tim, Let me know if you find the event manager docs lying around anywhere. I think I was able to work out a bit of it.
CSR_CAS_BUTTONS_EV_STATUS register is 1 when the button is being pressed and goes back to 0 on release. CSR_CAS_BUTTONS_EV_PENDING register starts off at 1 when the board is started. Writing 1 to any bit sets it back to 0. If the button is pressed it goes back to 1 and stays at one till it's written to again. I'm not sure if it should be 1 on boot, I would expect it to be 0 till the button is pressed for the first time. I can't work out what CSR_CAS_BUTTONS_EV_ENABLE is for. I can read and write to it and just keeps whatever value I give it. But the other registers function the same no matter what value is in this one. I'm thinking maybe it's for enabling interrupts? Not sure how I could test that though. Cheers, Karl -- You received this message because you are subscribed to the Google Groups "hdmi2usb - A HDMI capture solution" group.
