Note: For information on how to use MPLAB-IDE, ICD 2, or any other aspect of
the PICmicro Development tool platform, please refer to the appropriate
documentation.
Step Action Result
1 Connect ICD 2 to the PC and to the
PICDEM HPC Explorer Demo Board
—
2 Power up and program the PICDEM
HPC Explorer Demo Board with the
file “00106 - HPC.hex”
—
3 Disconnect the ICD 2 from the
PICDEM HPC Explorer Demo Board
PICDEM HPC Explorer Demo Board
program should now be operating
4 Configure the MCP4XXXDM-DB to
the jumper settings shown in
Figure 2-8.
—
5 Insert the MCP4XXXDM-DB board
into the PICDEM HPC Explorer Demo
Board J3 header. Ensure proper
orientation of Daughter Board to J3
Header.
—
Note: You may be required to
solder a 28-pin Female
header into the J3 header
socket.
6 Connect U1-P1A to the V
DD
connec-
tion post and U1-P1B to the V
SS
connection post.
—
7 Turn on oscilloscope and configure as
follows:
• Channel 1 to 4 @ 1V/Division
• Channel 1 to 4 have same
ground reference point
• Time-base = 200 ms/Division
—
8 Connect the oscilloscope probes as
follows:
• Channel 1 to the U1-P0W Pad
• Channel 2 to the U1-P1A Pad
• Channel 3 to the U1-P1B Pad
• Channel 4 to the U1-P1W Pad
Output waveform should look similar
to Figure 2-10.
