1. The Connect button attempts to establish a connection to the IR demo board.
The PC is acting as the Primary device and the demo board acts as the
Secondary device.
2. The Read Data button causes a query to be sent to the demo board requesting
a tally of the number of sodas and candies dispensed. Data received from the
demo board is parsed and displayed in text labels.
3. The Clear Data button sends a command to the demo board instructing it to reset
the application level counters.
4. The Send Byte button transfers the byte entered into the TX Data (ASCII) text
box. Any byte may be entered and transferred to the embedded system. If the
byte corresponds to one of the commands to read data, clear data or transfer a
buffer, the board will respond depending on its mode (vending machine or
250-byte transfer).
5. The Get File button initiates the 240-byte data transfer from the embedded
system by sending the embedded system the command byte for the transfer.
6. The Send File button allows the user to select a file on the PC and transfer it to
the embedded system.
7. The Close button closes the application.
