The PC may be a notebook with an integrated IR port.
Only required if data is communicated with the PC.
Some PICDEM™ HPC Explorer Demo Board program modes “respond” to
received data (data not sent to PC).

2.4.1
Two firmware programs are supplied with this board. 00077 - HPC.asm is for the
PICDEM HPC Explorer Demo Board, while 00077 - FS USB.asm is for the PICDEM
FS USB Demo Board.
The PICDEM HPC Explorer Demo Board supports three modes of operation:
1. Direct-to-PC.
2. Data Logger (250 byte data transfer).
3. Data Echo.
In Direct-to-PC mode, the data byte communicates between the MCP215X/40
Developer’s Daughter Board and the PICDEM HPC Explorer Demo Board’s DB-9
connector (does not communicate with the PIC18F8722). The PICDEM HPC Explorer
Demo Board is only used for the USART circuitry and power.
In Data Logger mode, a string of 250 bytes is transferred to the Primary Device after a
byte has been received.
In Data Echo mode, the data byte that is received is “echoed” in the opposite case
(lowercase
The PICDEM FS USB Demo Board only supports Data Logger and Data Echo modes.
The source code for these programs is available for download from the Microchip web
site (www.microchip.com), as well as being available on the CD-ROM supplied with the
MCP215X/40 Developer’s Daughter Board.
To use these programs, it is required that MPLAB
computer and that one of Microchip’s development tools are available to program the
board (such as MPLAB
