❶ stm8s的EEPROM讀寫程序如何編寫，需要哪些配置步驟
#define EEPMASS1 0xAE //密碼鑰匙1
#define EEPMASS2 0x56 //密碼鑰匙2
#define EEPADDR 0x4000 //eep地址起始
void eeprom_read(U16 u16Addr, U8 *pdatas, U8 len)
{
U8 *eep=(U8 *)u16Addr;
U8 j;
for(j=0; j<len; j++)
{
pdatas[j]=eep[j];
}
}
void eep_word_write(U16 u16Addr, U8 *pdatas, U8 len)
{
U8 *eep=(U8*)u16Addr;
U8 j;
FLASH_DUKR=EEPMASS1; //鎖1密鑰
FLASH_DUKR=EEPMASS2; //鎖2密鑰
while(!(FLASH_IAPSR&0x08)); //等待解密就緒
DISABLE_MAC_INTERRUPTS();
FLASH_CR2 |= 0x40; //
FLASH_NCR2 &= ~0x40; //設置字編程
for(j=0; j<len; j++)
{
eep[j] = pdatas[j];
}
while(!(FLASH_IAPSR&0x04));
FLASH_IAPSR &=0xf7; // off the eeprom program
ENABLE_MAC_INTERRUPTS();
}
