MAKING A DEMO SYSTEM
Hardware
The MCP212X Developer’s Daughter Board requires a clock source and either a Host
Controller or a UART circuit. To demonstrate the board, the easiest method is to use
one of the compatible PICDEM™ Demo Boards. A good choice is the PICDEM™ HPC
Explorer Demo Board. This allows the MCP2120 device to interface to either:
• PIC18F8722’s EUSART1
• PIC18F8722’s EUSART2
• PICDEM™ HPC Explorer Demo Board’s DB-9 connector (MAX3232C)
Additional instructions for performing a demo using the PICDEM™ HPC Explorer
Demo Board are shown in Appendix D. “Using the MCP212X Developer’s Daughter
Board with the PICDEM™ HPC Explorer Demo Board”. Appendix E. “Using the
MCP212X Developer’s Daughter Board with the PICDEM™ FS USB Demo Board”
supplies instructions for performing a demo using the PICDEM™ FS USB Demo
Board. Appendix F. “Configuring the HyperTerminal
configuring the HyperTerminal program on the PC.
System Requirements
Table 2-3 shows the requirements for a system that can be used to demonstrate the
MCP212X Developer’s Daughter Board.
System Setup
The system setup requires a PC with two serial communication ports (UARTs) and
HyperTerminal, the system application program. Two PICDEM™ HPC Explorer Demo
Boards and two MCP212X Daughter Boards are then needed.
Figure 2-4 shows a system block diagram.
TABLE 2-3:
Note:
The MCP2122 may be installed in U4, or the MCP2120 may be installed in
U1. However, these devices should not be installed at the same time.
SYSTEM HARDWARE REQUIREMENTS
Purpose
The PC will “talk” to each PICDEM™ HPC Explorer Demo Board
(Encoder/Decoder board) via the serial port and an instance of the
HyperTerminal
“System #1” PICDEM™ HPC Explorer Demo Board. Com 2 will be used to
communicate to the “System #2” PICDEM™ HPC Explorer Demo Board.
To connect the PC serial ports to each PICDEM™ HPC Explorer Demo
Board’s serial port.

This board will be used to communicate with the system under test.
Used to power each of the PICDEM™ HPC Explorer Demo Boards.
