Please help with SPI initialization on LPC2368

[kender]

Colleagues,

Please help me with SPI initialization on LPC2368.
Could anyone post code for initialization of SPI0 on LPC2368?
I can't make my own code work (SCLK doesn't show on the oscilloscope, when it's supposed to).

Thanks!

P.S. I don't forget to click "helped me" for those who helped.

Hi

Are you using Interrupt & DMA in your code?

Whether you are not using - try to search for SPI code for the LPC21xxx it has allmost the same setup

As far as I remember (I have upgraded to ARM cortex a year ago - the ARM7 is a bit old for me) there is good sources of code examples at NXP site as well and many other site in the WWW

All the best

Actually, my problem was in h/w rather than f/w. I have mixed-up SSP0 pins (34, 37, 38 ) and SPI pins (60, 61, 62). This is my 1st design with LPC2000. Wrote the code to make SSP0 work as an SPI master.

P.S. Out of curiosity: why does the chip have two SSPs, which can do all SPI functions, and a redundant dedicated SPI peripheral ? Which one is preferable for SPI?
