Project Overview
The project
CY8CKIT_40_CapSense_I2C.cyprj
demonstrates the implementation of a CapSense
Trackpad using SmartSense and an EzI2C-based CapSense Tuner window for viewing the Track-
pad coordinates. The project is a simple implementation using SmartSense (minimal tuning). The
EzI2C block of PSoC 4000 is interfaced through the PSoC 5LP based USB-I
2
C bridge to the PC
GUI. The project uses the SmartSense feature, which sets all CapSense parameters to the optimum
values automatically. The parameter settings can be monitored in the GUI but cannot be altered. In
the manual tuning method, parameter settings can be changed in the GUI, and the resulting output
can be seen (refer to the
and CapSense Component datasheet for more
details on manual tuning).
Note:
This project requires the Trackpad shield board to be plugged into the PSoC 4000 Pioneer Kit
.
