IAR STM8 1.2 直接使用__eeprom关键字访问EEPROM
STM8L15X:
#include "stm8l15x_conf.h"
void __eeprom_write_8(unsigned short addr_eep,unsigned char data)
{
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_Unlock(FLASH_MemType_Data);
FLASH_ProgramByte(addr_eep, data);
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_Lock(FLASH_MemType_Data);
}
void __eeprom_write_16(unsigned short addr_eep,unsigned short data)
{
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_Unlock(FLASH_MemType_Data);
FLASH_ProgramByte(addr_eep, data/256);
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_ProgramByte(addr_eep+1, data%256);
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_Lock(FLASH_MemType_Data);
}
void __eeprom_write_32(unsigned short addr_eep,unsigned long data)
{
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_Unlock(FLASH_MemType_Data);
FLASH_ProgramByte(addr_eep, (unsigned char)(data>>24));
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_ProgramByte(addr_eep+1, (unsigned char)(data>>16));
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_ProgramByte(addr_eep+2, (unsigned char)(data>>8));
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_ProgramByte(addr_eep+3, (unsigned char)(data>>0));
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_Lock(FLASH_MemType_Data);
}
void __eeprom_write_many(unsigned short addr_eep,unsigned short size,unsigned short dummy,unsigned short addr_ram)
{
FLASH_WaitForLastOperation(FLASH_MemType_Data);
FLASH_Unlock(FLASH_MemType_Data);
for(unsigned short i=0;i<size;i++)
{
FLASH_ProgramByte(addr_eep+i, *((unsigned char *)(addr_ram)+i));
FLASH_WaitForLastOperation(FLASH_MemType_Data);
}
FLASH_Lock(FLASH_MemType_Data);
}
STM8S:
#include "stm8s_conf.h"
void __eeprom_write_8(unsigned short addr_eep,unsigned char data)
{
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_Unlock(FLASH_MEMTYPE_DATA);
FLASH_ProgramByte(addr_eep, data);
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_Lock(FLASH_MEMTYPE_DATA);
}
void __eeprom_write_16(unsigned short addr_eep,unsigned short data)
{
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_Unlock(FLASH_MEMTYPE_DATA);
FLASH_ProgramByte(addr_eep, data/256);
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_ProgramByte(addr_eep+1, data%256);
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_Lock(FLASH_MEMTYPE_DATA);
}
void __eeprom_write_32(unsigned short addr_eep,unsigned long data)
{
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_Unlock(FLASH_MEMTYPE_DATA);
FLASH_ProgramByte(addr_eep, (unsigned char)(data>>24));
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_ProgramByte(addr_eep+1, (unsigned char)(data>>16));
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_ProgramByte(addr_eep+2, (unsigned char)(data>>8));
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_ProgramByte(addr_eep+3, (unsigned char)(data>>0));
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_Lock(FLASH_MEMTYPE_DATA);
}
void __eeprom_write_many(unsigned short addr_eep,unsigned short size,unsigned short dummy,unsigned short addr_ram)
{
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
FLASH_Unlock(FLASH_MEMTYPE_DATA);
for(unsigned short i=0;i<size;i++)
{
FLASH_ProgramByte(addr_eep+i, *((unsigned char *)(addr_ram)+i));
FLASH_WaitForLastOperation(FLASH_MEMTYPE_DATA);
}
FLASH_Lock(FLASH_MEMTYPE_DATA);
}
主程序测试：
volatile __eeprom __no_init char eep_u8;
volatile __eeprom __no_init short eep_u16;
volatile __eeprom __no_init long eep_u32;
void main( void )
{
eep_u8=123;
eep_u16=12345;
eep_u32=123456789;
while(1);
