NIOS Based Example Codes

Can’t wait to get started with the DECA board? We provide several NIOS based examples for you
to try them on the DECA board. All of the NIOS based examples can be found in the System CD
under the folder Demonstrations. You are free to use them or modify these examples in your future
design!

There is a special capacitive touch sensor called CapSense on DECA board. Capacitive touch
sensors are user-interface device that use the capacitance of the human body to detect the presence
of a finger on, or near, a sensor.

Figure 6-1

s

hows the system block diagram of this reference design. The capacitive touch sensor

chip  CY8CMBR3102  is  controlled  through  I2C  interface.  In  this  design,  an  I2C  OpenCore
controller is used to communicate with the CY8CMBR3102. The NIOS program controlls the IC2
OpenCore  based  on  a  specified  I2C  OpenCore  c-code  library.  The  NIOS  program  use  polling
method the monitor the touch sensor status.
