Note:
Connect ICD 2 to the PC and to the
PICDEM FS USB Demo Board
Power up and program the PICDEM
FS USB Demo Board with the file
“00106 - FS USB.hex”
Disconnect the ICD 2 from the
PICDEM FS USB Demo Board
Configure the MCP4XXXDM-DB to
the jumper settings shown in
Figure 2-9.
Insert the MCP4XXXDM-DB board
into the PICDEM FS USB Demo
Board J6 header. Ensure proper
orientation of Daughter Board to J6
Header.
Connect U1-P1A to the V
tion post and U1-P1B to the V
connection post.
Turn on oscilloscope and configure as
follows:
• Channel 1 to 4 @ 1V/Division
• Channel 1 to 4 have same
• Time-base = 200 ms/Division
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
