#include "mbed.h" #include "USBMSD_AT45.h" USBMSD_AT45 Flash(p5, p6, p7, p8, 512); // Mosi, Miso, Sclk, CS, Size of block being transported over USB // each time. Can be 512, 1024, 2048, 4096. Best is to select same // size as AT45DBxx SRAM buffer size. If page size of flash is not // binary 2^N (256, 512, 1024 bytes) but is 264, 528 or 1056 bytes // before each write we read block being written to SRAM then rewrite // part of them with data from host and write whole SRAM buffer back // to flash. This avoids to data being rewritten in other blocks // we actually do not write to. int main() { while(1) { // Do something else here } }
