LPC2468 SPI problem
pins which can be used for the SPI, but we can only get one of the sets
If we configure the SPI to use the pins in PORT 0, (PINSEL0=0xC0000000
and PINSEL1=0x0000003C) then it works fine.
If we set PINSEL5 to configure SPI in PORT 2, (PINSEL5=0x00F03000)
nothing emerges from the pins (although the SPI seems to be working
The datasheet confusingly says that you should set PINSEL0-PINSEL4 but I
presume this is a typo for PINSEL5.
Can anybody suggest what we might be doing wrong?
