5. CP2112 Software Interface
The CP2112 is an HID device that uses the standard HID functions available in the operating system. To facilitate
this process in Windows, Silicon Labs packaged the standard HID functions into the SLABHIDDevice DLL in the
CP2112 software package. The HID report structure for the CP2112 is customized for the device and is not
compatible with other HID report structures, like a mouse or keyboard. AN495, âCP2112 Interface Specificationâ
describes the custom HID report structure for the CP2112, and AN496, âCP2112 HID-to-SMBus API Specificationâ
describes the API software functions that can be used to read or write data and control the CP2112 from the PC.
The software application described in â6. CP2112 Windows Applicationâ provides an example of how to use these
functions.
The CP2112 appears as an HID device in Device Manager as shown in Figure 2.
