问 am29lv160dt flash 擦除某一sector时怎么全片都擦除了
这是下面的代码，请高手看看有没有写错。

void flash_erase(P_U16 base_addr){
    
    
    P_U16 Temp;
    U32 i=35000000;
    
         /*  Issue the Sector Erase command to am29lv160dt  */

         Temp  = (P_U16)((0x0000555<<1)+FLASH_ADDRESS);          　　　　　　　*Temp = 0xAA;                 
         Temp  = (P_U16)((0x00002AA<<1)+FLASH_ADDRESS);          　　　　　　　*Temp = 0x55;                
         Temp  = (P_U16)((0x0000555<<1)+FLASH_ADDRESS);         
          *Temp = 0x80;                 
         Temp  = (P_U16)((0x0000555<<1)+FLASH_ADDRESS);
          *Temp = 0xAA;                
         Temp  = (P_U16)((0x00002AA<<1)+FLASH_ADDRESS);
          *Temp = 0x55;                
         Temp  = base_addr;                     
         *Temp = 0x30;                 
         while(i--);//Delay
} 答 1: 有没有人用过个flash呢有没有人用过个flash呢 答 2: re:woaini看看我的擦除操作：
#define WRITE_FLASH(uiAddr,usData)    *((volatile INT16U *)(uiAddr << 1))= usData

void  bSST39VF160SectorErase(INT32U uiAddr)
{
    WRITE_FLASH(0x5555, 0xAA);
    WRITE_FLASH(0x2AAA, 0x55);
    WRITE_FLASH(0x5555, 0x80);
    WRITE_FLASH(0x5555, 0xAA);
    WRITE_FLASH(0x2AAA, 0x55);
    WRITE_FLASH(uiAddr, 0x30);
    bWaitForEndOfPrg();//判断是否写入完成函数
}
答 3: SST39VF160 的我的程序也可以用在SST39VF160的是可以的.
#define WRITE_FLASH(uiAddr,usData)    *((volatile INT16U *)(uiAddr << 1))= usData

void  bSST39VF160SectorErase(INT32U uiAddr)
{
    WRITE_FLASH(0x5555, 0xAA);
    WRITE_FLASH(0x2AAA, 0x55);
    WRITE_FLASH(0x5555, 0x80);
    WRITE_FLASH(0x5555, 0xAA);
    WRITE_FLASH(0x2AAA, 0x55);
    WRITE_FLASH(uiAddr, 0x30);
    bWaitForEndOfPrg();//判断是否写入完成函数
}
但在am29lv160dt就不行,代码如下:
#define WRITE_FLASH(uiAddr,usData)    *((volatile INT16U *)(uiAddr << 1))= usData

void  bAM29VF160SectorErase(INT32U uiAddr)
{
    WRITE_FLASH(0x555, 0xAA);
    WRITE_FLASH(0x2AA, 0x55);
    WRITE_FLASH(0x555, 0x80);
    WRITE_FLASH(0x555, 0xAA);
    WRITE_FLASH(0x2AA, 0x55);
    WRITE_FLASH(uiAddr, 0x30);
    bWaitForEndOfPrg();//判断是否写入完成函数
} 答 4: 我用过没问题啊//--------------------------------
//Erase all data on chip
//--------------------------------
void chip_erase( void )
{
    SFRPAGE = 0x0F ;
    CE_H() ;
    WE_H() ;
    OE_H() ;

    out_byte( 0x555, 0x55 );
    
    out_byte( 0xAAA, 0x80 );
    
    out_byte( 0xAAA, 0xAA );
    
    out_byte( 0x555, 0x55 );
    
    out_byte( 0xAAA, 0x10 );

    wait_ready1();
    
}

    out_byte( addre, 0x30 );


   
    wait_ready2();
