If you are using the EEProm Emulation driver, you had bettern add a function such as check the data after write finished. For example, if you have 10 data to save, so you need write 11 bytes to flash. The last byte is checksum. And check the data after read from flash. Share Impro...

1、选用的是SPI1,全双工主机模式(单片机是主机,外部FLASH做从机),片选引脚由软件控制。 2、再检查一下SPI1的引脚设置是否正确。 3、设置FLASH的片选引脚即PC0引脚为输出模式,因为SPI1上只有一个器件,默认输出低电平。 五、生成代码 1、SPI1初始化代码如下所示: ...
