在调用这个函数之后我们需要延时一段时间或者使用回调函数判断,之后再调用下一段IIC函数,详细的可以看下面IIC的写入代码, 原因是因为当你使用了R_IIC_MASTER_Write函数之后,IIC通信还未完成, 如果你再次调用其他的IIC函数就会覆盖掉第一次执行的函数, 从而出现时序错误。 22.4.2.4.R_IIC_MASTER_Read 函数¶ 代码...
EEPROM 是使用与 EPROM 相同的技术的存储器部件,但是存储的每一位都有额外的晶体管以允许单独擦除该位。术语 EEPROM 表示"Electrically"/"Erasable" / "Programmable" / "Read Only Memory"。发音为double-ee-prom or e-e-prom,这是一个小芯片的长名称,它保存着可以通过电荷重写和擦除的数据代码,一次一个字节...
