Chapter 5. Reconfiguring the PICDEM™ FS USB Hardware
HIGHLIGHTS
CONFIGURING THE DEMONSTRATION BOARD OPTIONS
This chapter covers the following:
• Configuring the Demonstration Board Options
• Restoring the PICDEM™ FS USB Firmware
The PICDEM FS USB board can be configured to enable or disable its various hard-
ware features. A total of 16 jumper locations are controlled in various places around the
board. As shipped from the factory, all of the locations are bridged by circuit traces and
all of the features are enabled. To change this, the user will need to cut the traces, and
install pins and a block jumper. Afterwards, the features can be enabled or disabled
easily by installing or removing the jumper.
In some instances, a single function (such as the digital temperature sensor) is
connected to the rest of the board through more than one jumper. This allows selective
tailoring of the controller’s I/O ports to any application that the user may develop.
Specific cases are discussed in the following sections.
The functions of the jumpers are listed in Table 5-1; their locations are shown in
Figure 5-1.
