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:

Set jumper J13, as shown in the second illustration in Figure 2-10.

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:

Create a folder named, HPCINF, anywhere on the host PC’s hard drive.

Using the development kit’s CD, copy the file, mchpcdc.inf, into that folder.

Connect the board to the PC and power up the board. The pop-up window,

shown in Figure 2-11, appears.

operating system.
