DEMONSTRATION APPLICATIONS
The five demonstration applications developed for the daughter board are described in
this section. Peripherals on the Explorer 16 Development Board, such as the LCD
screen, push buttons and LEDs, are used by the demonstration applications to interact
with the user. In general, LED D3 indicates the transmission status, LED D5 indicates
the receiver bit synchronization status, and LED D4 indicates the receiver byte
synchronization status.

applications. The listed memory requirements are valid only when the default
configuration settings are used (source codes provided on the web site are configured
with default configuration settings). Changing the configuration settings may cause
significant changes in the memory requirements.
TABLE 3-2:
3.2.1
This demonstration evaluates the two-way power line communication link between two
development boards.
1. Program two Explorer 16 Development Boards with the same demonstration
2. Connect the development boards to a power line and power up the Explorer 16
3. Press the S5 button on one of the Explorer 16 Development Boards, for example,

board 1.
This will cause board 1 to transmit a predetermined frame on the power line. The
other board, board 2, connected to the same power line will receive this frame
and check it for errors. If no errors are found, board 2 will transmit another pre-
determined frame on the power line. Again, board 1 will receive this frame and
check it for errors. If no errors are found, board 1 will transmit another predeter-
mined frame on the power line. This process continues as an infinite loop, ping-
ing data frames back and forth over the power line. Meanwhile, the LCDs on the
two Explorer 16 Development Boards display the following frame statistics
information:
• TX: Number of frames transmitted
• RX: Number of frames received in total
• ERR: Number of frames received with errors
