Re: [lpc2000] Re: accesing SPI registers

2005-05-25 by Jaromir

I use GCC and in lpc2114.h all registers are defined as
#define SPI_SPxx  (*(REG32 (0xE0020000)))

so I should change to  #define SPI_SPxx  (*(REG8 (0xE0020000)))    ???

  Hello, there's a small example on Philips website.
  have a look here :

  and look at "AN10369_1: UART/SPI/I²C code examples (date 12-Apr-05)"
