I have been trying to use the LCP1767 SSP port in SPI mode. I can get it to work if I set the FIFO to 1 byte. If I set it to more, it mostly works, but sometimes I don't get all my read bytes back. Example, I'll send 20 bytes, and receive back only 19.

I am using linear buffers for the transmissions.

Does anyone have good working code using the FIFO and interrupts?

Hi Tuhsar,
The example is got from lpc175x_6x repo at http://sw.lpcware.com/?p=lpc175x_6x.git&a=summary. IAR example is also available here.
