Class SerialComHID

java.lang.Object

com.embeddedunveiled.serial.hid.SerialComHID

Direct Known Subclasses:

SerialComRawHID

public class SerialComHID
extends Object

The SCM library provides two set of APIs for communicating with a HID device. First is raw HID communication using methods in SerialComRawHID class. In raw mode, input reports received and sent output reports are not parsed. Second is SerialComParsedHID class in which reports are parsed.

In Windows, system supplied HID minidriver and HID class drivers provide most of the functionality and required support for HID-compliant devices. However we may have to write our own HID minidriver if it is difficult to make desired changes to HID-compliant device firmware or if we need to make a non-HID compliant device into a HID device without updating the firmware.
