使用FM25L16B和STM32 SPI通信的问题，原始代码是错的，应该修改如下

[Home-Laozang]

`/* 设置写使能所存器*/
void SetWriteEnableLatchForFM25xxx(FM25ObjectType *fram)

uint8_t opCode = FM25_WREN;

fram->ChipSelect(FM25CS_Enable);
fram->Write(&opCode, 1);
fram->ChipSelect(FM25CS_Disable);/*此处应该是DISABLE，好几处这里都需要修改 */

ReadStatusForFM25xxx(fram);

}

/向FM25xxx写入数据/

}
