KCU1250 Board Features and Operation
User DIP Switches (Active-High) and I/O Header
The DIP switch SW3 (callout 26,
) provides a set of eight active-High switches
which connect to user I/O pins on the FPGA, as shown in
. These pins can be used
to set control pins or any other purpose you choose. The eight I/Os also map to a test
header J95 (callout 29,
), providing external access for these pins. The I/O pins
can be connected to the onboard system controller as additional GPIO between the two
devices.
IMPORTANT:
Install J7 to connect the user DIP switches to the system controller.
