这里面是在写入数据在开机就变成附件中的了。
这是读取数据的代码：(ep2 out) for(R_count=0;R_count<511;) { while(!(UEPSTAX&0x40)); total=UBYCTX; for(d_count=0;d_count<total;d_count++) { Read_data[R_count]=UEPDATX; R_count++; } CLEAR_BIT_6(UEPSTAX); while(!(UEPSTAX&0x02)); total=UBYCTX; for(d_count=0;d_count<total;d_count++) { Read_data[R_count]=UEPDATX; R_count++; } CLEAR_BIT_1(UEPSTAX); } //-------------------------------------------------------- 这是写入代码 do{ if(LBA_Swicth) { //-----------Initialize-Source-address------------------ Write_LBA_S=Write_LBA; ST=Write_LBA_S/32; //div //Block number SM=(BYTE)(Write_LBA_S-(ST*32)); //mod //page in block //current page number S_LBA=ST*32; //first page number in block //--------------------Destination--address-Find-------------- D_LBA=128; //destination address // =5 S_D_LBA=(BYTE)(ST%4); // ST MOD 4 D_LBA=D_LBA+(S_D_LBA<<5); //plane select Nand_Erase_one_block(D_LBA); TEMP1 =S_LBA; TEMP2=D_LBA; //------------------read-first->current-pages-------------- for(i=0;i<SM;i++) { //------------------data-----512B------------------ Nand_Copy_page(0x00,S_LBA,0x00,D_LBA); S_LBA +=1; //source address D_LBA +=1; //destination address } LBA_Swicth=0; //LBA_Address Switch :1= real address ,0= Dummy(Temp) address } //----------------------data-Write-------512B----------------------------------- LED=1; USBEP2_Read_Mass_data(Temp_Buffer); //Read data(512Bytes) from host LED=0; Key1=0; Nand_Write_one_Page(0x00, D_LBA, Temp_Buffer); //Write data to Dummy Address D_LBA ++; S_LBA ++; SM ++; //Address increase //--------------Tail-data-opinion---------------------------------------- if(Write_Page>0) { Write_Page --; Write_LBA ++;} //real address increase //--------------Tail-Page-Write-------------------------------------------- if((SM >=31)||(Write_Page==0)) // end Page in block OR data write complete { //----------Tail-page-write-temp-address------------ for(;SM<32;SM++) { //--------512B------------------------------- Nand_Copy_page(0x00,S_LBA,0x00,D_LBA); S_LBA +=1; // source address D_LBA +=1; // destination address } //------------Erase-Source-Block---------------------- Nand_Erase_one_block(TEMP1 ); //------------------------------------------------ D_LBA=TEMP2; //destination address reset to the first page in the block S_LBA=TEMP1; //source address reset to the first page in Block for(i=0;i<32;i++) { //---------Copy-back-data---512B----------------------------- Nand_Copy_page(0x00,D_LBA,0x00,S_LBA); S_LBA ++; D_LBA ++; } LBA_Swicth=1; //next Block reset } }while(Write_Page>0); //------------------------Clear-Receive-Trigger--------------- if(UEPSTAX&0x42) { CLEAR_BIT_6(UEPSTAX); CLEAR_BIT_1(UEPSTAX); //clear RoutB0 for recieve next data endpoint number LED_G=1; } } |
