Hi,

Just to note:
LPCXpresso LPC800 rev B board schematic shows PIO0_10-SDA and PIO0_11-SCL on page 5 on the LPC expansion connector J6

The pins P0_10 and P0_11 are indeed routed from the LPC812 microcontroller to these pins on J6. But the function on the LPC812 for pin P0_10 is SCL and P0_11 is SDA.

So CLK and SDA are swapped.
