user push button

Former Member

Hi,

So I just would like to know with the SW1 which is a USER GPIO button. In the documentation it says it is connected to B9 and when checking UG865, this pin is connected to the PS. Is their a way of simply using it to trigger something in the PL? Or is there another way of triggering something in the PL with the microZed?

    Hi Gary

    I'm working with MicroZed too. I'm interested in your following option:

    "You could use the switch indirectly by having one of the ARM processors read the state of SW1, and set a GPIO output routed via the EMIO to the PL section accordingly, to control PL logic."

    How could I do it with Vivado 2013.4 ?

    I added an AXI_GPIO_0 bloc but Vivado doesn't propose to me any "run connexion automation" solution.

    Thanks

    Guillaume
