本文主要是介绍EEPROM连续写多个字节函数接口，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
EEPROM连续写多个字节函数接口
void ee_24c256_writebytes(u16 write_addr, char* pwrite_buff, u16 writebytes)
{u8 write_len,page_offset;while(writebytes > 0){page_offset = EE_PAGESIZE - (write_addr % EE_PAGESIZE); /*EE_PAGESIZE为页大小，如24c256为64*/write_len = writebytes > page_offset ? page_offset : writebytes;i2c_24c256_write(write_addr,pwrite_buff, write_len); /*写一页函数*/writebytes = writebytes - write_len;if(writebytes > 0){pwrite_buff = pwrite_buff + write_len;write_addr = write_addr + write_len;i2c_24C256_waitstandby(0); /*页写判忙,*/}}
}
注：EEPROM的一次写操作不能跨页。
这篇关于EEPROM连续写多个字节函数接口的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
