The LEDs are connected to turn ON when the port pins are high.
For troubleshooting I have turn LED1 ON as soon as the SPIF flag is set indicating a successful data transfer. The LED1 does not turn ON at all, hence i came to the conclusion that the while statement to check for SPIF flag stalls the code execution. Aquib |
