Using the I 2 C? GUI Interface Demo Tool
The GUI interface gives the user the following options to interact with the controller
board:
-
-
-
-
-
-
Reset the PICkit Serial (to reset communications)
Receiver Test: for testing communications
Clear Message: Clears message box
Individual Read Request and Continuous Read (every 300 ms)
Receiver Commands: Erase and Learn Transmitter

RESETTING THE PICkit? SERIAL
Press the RESET PKSA button to establish communications to the PICkit Serial
Analyzer either at start-up or when a communications problem has arised.
COMMUNICATIONS TEST
This command sends predefined data to the controller board. This data is displayed on
the controller LCD as:
Test Buffer
01234567
Use this command to verify the integrity of the communication.
ERASING AND LEARNING TRANSMITTERS
To erase all transmitters learned by the Controller board click the ERASE ALL check
box, then click on the Transmit button. A message on the text box will display if the
erase command was successful.
To Learn a transmitter, click the LEARN TRANSMITTER check box, then click on the
Transmit button. A message on the text box will display if the learn command was
successful.
RECEIVING DATA
Two receiving modes are available: on demand and continuous.
When clicking on the Read Request button, a single read command is sent through to
the controller board. The controller will send the decoded information of the last trans-
mission received.
Checking the Continuous Read box will send a read request to the controller board
every 300 ms. The information on the current last transmission is sent to the GUI at this
rate.
