When you are using the spi in master mode you also need to map SSEL to pin
P0.7 and drive it high.

Oggetto: [lpc2000] SPI interface usage



Hello ,

I am new to lpc2000 user group.Was happy to know
about such a platform. I had some problem regarding
the  SPI interface.

While implementing a simple SPI transfer to a
memory thro KEIL debugger, I found a problem in the
simulation:

After I write the clock control to the clock control
register, control parameters to the control
register, and data to data register(target device
LPC2106),I find the parameters are correctly getting
loaded in the SPCCR and SPCR register during
debugging but data is  getting loaded in the data
register(in the peripherals GUI).

Here is the piece of code:-

char temp=0x10;

PINSEL0|=0x00005500;

 SPCCR=0x08;
 SPCR=0x20;
 SPDR=temp; // this value not getting loaded
correctly.

Could anybody help me out with this.

Umesh
