Hi everyone!

I am using a lpcxpresso baseboard with a LPC1769 stick.
I want to learn how to use the SPI driver of LPCOpen, to write and receive bytes to/from peripherals. So I want to try with the shift register that is connected to the 7-segment display in the baseboard.

I have´t been able to make it work yet. Has someone worked with it? Is there any example?

Some of my problems could be:
  -using the correct SSEL for the shift register. I am not sure about it. I am using the pin P2[2] of the LPC1769.
  -setting the jumpers in the board
  -not asserting correctly the RCLK signal (shift register).

Thanks in advance.
