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

FM25CL64 FRAM IC controlled through SPI interface reading and writing functions using atmel atmega-FM25CL64 FRAM IC controlled through SPI interface reading and writing functions using atmel atmega88

基于STM32处理器SPI接口的FRAM存储器程序，项目中用到的，原创，读写等基本函数均已写好，可直接使用-STM32 processor SPI interface based on FRAM memory process, the project used, original, read and write basic functions have been written, can be used directly
