EXAMPLE 2-7:
Note that the HID mouse transmits in 3-byte packets. The format of this packet is as
follows:
• This byte is typically used to identify mouse buttons. Since this application does
• The second and third bytes represent horizontal (X) and Vertical (Y)
Compile the project. There should be no errors.
Testing the Application
9. Ensure that the Low Pin Count USB Development Board is configured as in Lab 1.
10. Connect the PICkit 2 Programmer and open the PICkit 2 programming software.
11. Navigate to the .hex file located in the C:\LPCUSBDK_Labs\Lab2_files for
not require any mouse clicks, this byte is always zero.
