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...

In the _read(…) function, the 'len' parameter passed in was found to always be '1024' for the library and build environment used to develop the example code. int_read(intfile,char*ptr,intlen) In order to support the use of getchar(), the expression 'len = 1;' was added immediat...
