#pragma location="LCD_region"
char lcd_buffer[8][256];
#pragma location="BG_region"
long lcd_points[8*256*8]
這段代碼在IAR下能正常運(yùn)行，移植到keil5上面就報(bào)warning；
keil環(huán)境下可以用什么代碼代替這四段代碼！在線等
gui\LCD\lcd.c(18): warning:  #161-D: unrecognized #pragma
這兩個(gè)數(shù)組應(yīng)該是定義12864LCD RAM的
void drawPoint(short x, short y, char value)
{
      unsigned short location;

      assert( (x<132));assert((y<64));
      assert( x>=0); assert((y>=0));
      location= y&0x7;
      location +=(y>>3)<<11;
      location += (x<<3);
      lcd_points[location]=value;
}
void paintRect(short x0, short y0, short x1, short y1)
{
      char *pchar;
      char temp_x0;
      y0 =y0>>3;
      y1 =(y1+7)>>3;

      for(;y0<=y1;y0++)
      {
               WriteCommand(0xb0 | (y0));
            WriteCommand(0x10 | (x0>>4));
            WriteCommand(0x0F & (x0));
            WriteCommand(0xE0);

            pchar = &lcd_buffer[y0][x0];
            temp_x0=x0;
            for(;temp_x0<=x1;temp_x0++){
                     WriteData(*pchar++);
            }
      }
}這個(gè)兩個(gè)數(shù)組只用在這兩個(gè)函數(shù)里面  然后這兩個(gè)函數(shù)被LCD底層驅(qū)動(dòng)函數(shù)調(diào)用

下面是IAR .icf文件內(nèi)容  在keil里面應(yīng)該怎么實(shí)現(xiàn)
#define symbol __ICFEDIT_region_RAM_LCD_start__ = 0x20004000;

#define symbol __ICFEDIT_region_RAM_BG_end__ = 0x2208FFFF;

#define region BG_region = mem:[from __ICFEDIT_region_RAM_BG_start__ to __ICFEDIT_region_RAM_BG_end__];

去掉兩行，然后
char lcd_buffer[8][256];

long lcd_points[8*256*8]；
這兩行根據(jù)自己的存儲(chǔ)器可定義為：
char xdata lcd_buffer[8][256];

long xdata lcd_points[8*256*8]；
這樣編譯就不會(huì)出錯(cuò)了

謝謝！不太明白您的意思我的問題加了補(bǔ)充了麻煩看一下謝謝

看了很多資料問題已解決，下面兩行代碼完美解決
char lcd_buffer[8][256]__attribute__((at(0x20004000)));

long lcd_points[8*256*8]__attribute__((at(0x22080000)));

查了很多資料，問題已解決。替換成下面兩行代碼。完美解決
char lcd_buffer[8][256]__attribute__((at(0x20004000)));

long lcd_points[8*256*8]__attribute__((at(0x22080000)));
