6.3.3. Running the Host Application

1. Once firmware has been downloaded to the target board and the driver has been installed successfully, run

the USBTest.exe example application located by default in the “SiLabs\MCU\Exam-

ples\C8051F34x\C\USB_INT” directory.

2. The USBTest application will display the status of the potentiometer, the temperature sensor, the two

switches, and the lower four bits of Port 0.

3. The application also includes check boxes for turning on the two LEDs and changing the logic levels on the

lower four bits of Port 1.

4. If any of the application functions do not operate correctly, verify shorting blocks are installed at the follow-

ing positions: J3[1-2] (P2.0 Switch), J3[3-4] (P2.1 Switch), J3[5-6] (P2.2 LED), J3[7-8] (P2.3 LED), and J16

and J17 (P2.5 Potentiometer).

5. See Figure 4 on page 8 for the location of headers, LEDs, switches, and potentiometer.

Note: The C8051F340 target board has the ability to be powered through the USB cable. To enable the USB powered mode,

short the pins labeled VBUS and VREGIN on the J8 header. Do not short all 3 pins on the J8 header.
