My final goal is to get SPI working with several LPC810's where one chip is the master and the remainder are all slaves simply crunching numbers.
However I am currently having trouble getting my connections to work.

The pin matrix is set up so that pins are configured as follows:
[list=1]
  [*] RESET
  [*] MOSI
  [*] MISO
  [*] SSEL
  [*] CLK
  [*] VDD
  [*] VSS
  [*] GPIO
[/list]

The power is being supplied from a single external 3.3v source.

However when we try to run our slave/master program that simply sends a random number from one chip to the other, the GPIO isn't turning on our light as it should after verification.
I'm not sure if the wiring is correct, I have supplied an image of my breadboard with one master and slave.

If there are any kinds of resources that might prove useful for what I'm trying to do, please let me know.

Any and all help will be greatly appreciated, thanks.
