下面以arduino leonardo介绍arduino自带的EEPROM使用方法,以及arduino插拔次数的计数方法,arduino中已经存在EEPROM类库,我们要使用得先调用EEPROM.h,然后使用write和read方法,即可操作EEPROM。二、arduino iDE中的例程(具体程序请从ide中添加)1.写入例程选择File>Examples>EEPROM>eeprom_write。2.读取例程...
痞子衡在文章开头的时候讲过,SPI EEPROM并没有什么成文的接口命令标准,但是各大厂商生产的SPI EEPROM无一例外都支持下表的6条命令,即READ(读内存)、WRITE(写内存)、WREN(写使能)、WRDI(写禁止)、RDSR(读状态寄存器)、WRSR(写状态寄存器),所以从软件接口层面而言,这6条命令就是SPI EEPROM事实上的接口命令标准...
