Hi Magu,

Disconnect the serial cable from the board.

The RX LED1 must stay ON after you release the push button "Program".
If the LED1 does not stay ON after you release the push button "Program",
then the program is not running in the PIC.

Note that when the serial cable is connected to the board, and you press
the "Program" push button, the LED will stay ON until the first 4 bytes are
received. (Until you press the button "Program Message To The Display EEPROM"
in the VB Application). After that the first 4 bytes are received, the LED is
toggled and will be toggled again after the next 4 bytes are received continuing
in the same way until the last byte of the message is received. So the LED is
blinking while receiving the data from the PC.

Again, with the serial cable disconnected, the RX LED1 must stay ON after you
release the push button "Program". If not, then the program is not running in the PIC.

Trent, can you please confirm my last sentence?

Best regards,

Luciano
