8. CP2130 Demo Windows Application
The
CP2130 Demo
uses the Windows SLAB_USB_SPI interface DLL to communicate with the on-board SPI slave
devices via the CP2130 USB-to-SPI bridge. The application controls the CP2130, which communicates with an
external 3-channel ADC and SPI EEPROM. Using the default jumper configuration, the 3-channel ADC is
connected to a potentiometer, external temperature sensor, and GPIO.5, the CP2130 CLKOUT signal. The
following steps describe how to start the application and demonstrate some of its features.
1.
Make sure that the hardware is connected to a Windows PC as shown in Figure 1. If the device is properly
connected, the green Active LED on the CP2130 Evaluation Board will turn on. After a few seconds of
inactivity, the green Active LED may turn off, and the red Suspend LED will then turn on to indicate that the
device has entered USB suspend mode. This is part of a power-saving feature called USB selective
suspend.
2.
