Appendix E. Using the MCP212X Developer’s Daughter
Board with the PICDEM™ FS USB Demo Board
E.1
DEMONSTRATION WITH THE PICDEM FS USB DEMO BOARD
To perform a demonstration of the MCP212X, two systems are needed. One system
will operate as an encoder/decoder passing information to the PC. This system may be
either the:
• MCP212X Developer’s Daughter Board (MCP212XEV-DB) plus the PICDEM™
HPC Explorer Demo Board (DM183022) or
• MCP2120 Developer’s Board (DM163008)
The second system is a MCP212X Developer’s Daughter Board (MCP212XEV-DB)
plus the PICDEM™ FS USB Demo Board (DM163025). This system operates in a
stand-alone mode and will “echo” the characters it receives (changing the case of the
received alpha character). Figure E-1 shows a block diagram of the demonstration
system.

The firmware for these demos is available on the Microchip web site, as well as on the
AIPD Evaluation Board CD-ROM. The file name is
00063 - FS USB.asm
. This code
must be programmed into the PICDEM™ FS USB Demo Board’s PIC18F4550 for
demo operation. This code requires the JP4 jumper to be in the documented state.
