This application will require a few changes to the usb_descriptor.c file to configure the
PIC18F14K50 as a HID keyboard. Note: the changes made to the report descriptor
were done using the HID Descriptor Tool downloaded from
opers/hidpage/. The user is encouraged to spend some time reviewing the contents of
this page and the resources available for developing HID applications.
1. Create a new project “Project Lab 3” as was done in the previous labs. The
2. Ensure that the Project Build Options are configured as was done in Lab 1 steps
3. Open the usb_descriptor.c file and scroll down to the interface descriptor.
4. Scroll down to the HID class specific descriptor and uncomment the size of the
5. Scroll down to the report descriptor and add the code in Example 2-8 in the
source files for Lab 3 can be found in:
C:\LPCUSBDK_Labs\Lab3_files
11 through 15.
Uncomment the Protocol Code definition //HID_PROTOCOL_KEYBOARD,
HID report macro //DESC_CONFIG_WORD(63),
The report descriptor has changed from the previous lab and will contain 63
components that the Host PC will need to identify this device’s keyboard
attributes.
