CY8CMBR3102 CapSense
capacitive-sensing user interfaces solution to easily replace mechanical buttons. The CapSense
controller communicates with FPGA through I2C bus.
Figure 3-13 Connections between the CapSense-buttons and the MAX 10 FPGA
There are two slide switches connected to the FPGA, as shown in
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.
