PC Connection Via USB Port
If the board PC communication is via the USB port, the data will be routed through the
PIC18LF2450 mounted on the board, to convert the RS-232 communication to the USB
protocol.
To connect the PICDEM PIC18 Explorer Demonstration Board to a host PC via the
USB port:
1. Set jumper J13, as shown in the second illustration in
Figure 2-10.2. Install the required file on the host PC. (See the following procedure.)
If the USB port is used, an *.inf file must be installed on the host PC. To do this:
1. Create a folder named, HPCINF , anywhere on the host PC’s hard drive.
2. Using the development kit’s CD, copy the file, mchpcdc.inf , into that folder.
3. Connect the board to the PC and power up the board. The pop-up window,
shown in Figure 2-11, appears.
Note:
This procedure displays the dialog boxes that appear for the Windows ? XP
operating system.
