i am working on keil IDE using realview mdk-arm for a project based on LPC1768
i made a header file as below
and a .c file as follows
now i made a main file in which i included this header file.
also by browsing added the c file to projects folder.
now when i make a call to xchg_spi there occurs an error saying
the above compiles without any errors when the static is removed.
why so?
i made a header file as below
Code:
#ifndef _test_h
#define _test_h
#include "diskio.h"
#include "spi.h"
#include "type.h"
#include "LPC17xx.h"
#define rcvr_spi() xchg_spi(0xFF)
static
BYTE xchg_spi (BYTE dat);
#endifand a .c file as follows
Code:
#include "test.h"
static volatile
DSTATUS Stat = STA_NOINIT; /* Disk status */
static volatile
UINT Timer1, Timer2; /* 1000Hz decrement timer */
static
UINT CardType;
#define xmit_spi(dat) xchg_spi(dat)
//#define rcvr_spi_m(p) SPI2BUF = 0xFF; while (!SPI2STATbits.SPIRBF); *(p) = (BYTE)SPI2BUF;
#define rcvr_spi_m(p) *(p) = xchg_spi(0XFF);
static
BYTE xchg_spi (BYTE dat)
{
return (BYTE)SPISend((uint8_t) dat);
}now i made a main file in which i included this header file.
also by browsing added the c file to projects folder.
now when i make a call to xchg_spi there occurs an error saying
the above compiles without any errors when the static is removed.
