how to create .mmc file from winhex
Click to expand...
any help about getting .mmc image file from a real sd card ..??
Click to expand...

(option A) using WinHex (v15)
from WinHex Menu: select Tool->Open Disk (or F9), then locate your real SD Card.
WinHex Menu again: select File->Create Disk Image (or Alt-C), the save the file as *.mmc

(option B) using USB Image Tool by Alex - recommended because it's simple and free
open the tool, then locate your SD card drive.
press "Backup", save the image file and just rename it from *.img to *.mmc file.


both options are tested on a real 32MB SD card and proteus v7.5/v7.6
 
you can use virtual usb drive also. Then you can implement FAT file system on virtual usb drive and create .mmc file. do the simulation using proteus read the file again using a pc. i have done this for a data logger and its working well
 
This is good but i want to confirm, if i can work with the blank text.mmc file and write to it through the SD

You can do this... please see my above post. you have to just change extention of file to .edk (as i remember) to .mmc
 

Just rename the .bin file to .mmc

You will need an external RAM, because the AT89C51 has only 128 bytes of internal general purpose RAM, and you need 512 bytes to read/write one sector.

Use a 64KB external RAM and you will be abble to write and read an entire cluster of any FAT.

The program, I think you will need to develop by your self.
