4.2.2 Software Setup for Capacitive Touch Demo
1. Start Code Composer Studio version 5.
2. In the TI Resource Explorer, look for an entry called controlSUITE and expand the Development Tools
section.
3. Expand the entry for BOOSTXL-C2KLED and look for the capacitive touch demo application project.
Follow the steps in the right pane of Resource Explorer to import, compile, program, and run the
example.
4. After the example is running, the LEDs can be controlled as follows:
(a) Press the Center button twice to initially turn the LEDs ON.
(b) Spinning one’s finger around the touch wheel, while the LEDs are ON, cycles through the color
spectrum.
(c) Pressing the Center button again turns the LEDs OFF.
(d) Subsequent (single) presses of the Center button turns the LEDs ON or OFF.

5.1 Resource Allocation
Figure 8 shows the various stages of the board in a circuit diagram format and illustrates the major
connections and feedback values being mapped to the C2000 MCU. Table 2 lists these resources. For
more detailed information, see the schematics and the device-specific data sheets.
