? Reprogramming and Restoring the Application Firmware
RECONFIGURING THE PICDEM.net 2 DEVELOPMENT BOARD HARDWARE
The PICDEM.net 2 Development Board is provided with a range of hardware features
for manual interaction, as well as a choice of two Ethernet interfaces. In its original
state, the main port (J1) is active and all interactive options are enabled. To allow the
greatest amount of hardware flexibility in developing new applications, users can
change any or all of these configuration options to suit the needs of their application.
3.2.1
Configuring the Hardware Options
The Development Board can be configured to enable or disable its various hardware
features. A total of 23 jumper locations are provided 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 (with the exception of JP9, discussed below). To change this,
the user will need to cut the traces, and install pins and block jumpers. Afterwards, the
features can be enabled or disabled easily by installing or removing the jumpers.
In some instances, a single function (such as the USART) 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 3-1; their locations are shown in
Figure 3-1.
