2812使用spi读写fm25cl64或者at25640的程序，已经测试通过。注意在在eeprom的datasheet中都写只支持spi的0或者3模式，但我用0模式一直调不通，改用spi模式才可以，程序中就是使用spi的1模式。-2812 to read and write using spi or at25640 procedures FM25CL64 have the test. Attention to the datasheet in the EEPROM are write only support spi mode 0 or 3, but I used the 0 model has been adjusted barrier before they can switch to spi mode, process is the use of one mode of spi.
