Low Pin Count USB Development Kit User’s Guide
19. Scroll down to the string descriptor section. String descriptors can be used to
describe a device for the user. At enumeration, the string descriptor will appear
at the lower right hand section of the screen notifying the user of the intended
purpose of the device. Copy and paste the code between the curly brackets for
both the manufacturer string descriptor and product string descriptor in
//ADD MANUFACTURER STRING DESCRIPTOR CODE HERE
and
//ADD PRODUCT STRING DESCRIPTOR CODE HERE
EXAMPLE 2-3:
MANUFACTURER STRING DESCRIPTOR FOR LAB 1
'M','i','c','r','o','c','h','i','p',
' ','T','e','c','h','n','o','l','o','g','y',
' ','I','n','c','.'
EXAMPLE 2-4:
PRODUCT STRING DESCRIPTOR FOR LAB 1
'M','o','u','s','e',
' ','E','n','u','m','e','r','a','t','i','o','n ',
' ','D','e','m','o'
Finally, the last descriptor to be added is the report descriptor.
Early in the development of the HID class specification, subclasses were
intended to be used to identify different HID device categories. However, it
became clear that due to the diverse variety of devices that could be imple-
mented in this class, a more robust definition method was required. Therefore,
this class does not use subclasses to define most protocols. Instead, a mecha-
nism called the report descriptor identifies data protocol and the types of data
provided for a device. It is here that such things as the number of buttons on a
mouse, the unicode key value ranges for a keyboard, and other such
characteristics are defined.
The USB organization has provided a number of documents and tools
specifically designed to implement the report descriptor that can be accessed at:
http://www.usb.org/developers/hidpage/
The user is encouraged to download the HID Usage Tables that define a report
descriptor for a given device. Also, the USB organization has further developed
a HID Descriptor Tool that will assist the developer in designing their own report
descriptors. The tool also includes predefined descriptors for commonly used
HID devices such as a mouse and keyboard. This document and tool can be
