Figure 3-11 Connections between the Push-buttons and the MAX 10 FPGA
Figure 3-12 Switch Debouncing
There are two ten switches connected to the FPGA, as shown in
. These switches are
used as level-sensitive data inputs to a circuit. Each switch is connected directly and individually to
the FPGA. When the switch is set to the DOWN position (towards the edge of the board), it
generates a low logic level to the FPGA. When the switch is set to the UP position, a high logic
level is generated to the FPGA.
