I have a little project in which I want to be able to have my FPGA automatically simulate "button presses" onto a device that is completely seperate from the FPGA. What I'm struggling with is figuring out how to set up a verilog module that would essentially "close" the connection between the switch, given that the switch is the kind of switch with contacts on the circuit board and uses a capacitive membrane to close the connection with a button press. My idea was that I would solder wires from each end of the switch and into the FPGA, then have the positive end as the input, with the negative (ground) end as the output, but am not sure how I can set up the module to recieve a signal from another module implemented in the FPGA to close that connection. Any help would be appreciated.
