Here is my SD MMC Card Fat16 Example project.

It is very good Example for SD MMC Card.

I dont like ccs, its buggy. microchip produce pic12 pic16 pic18 pic24 pic33, their  c
 compilers are different, features in c18 and c30 and c32 are also different. i think  developers using them are hard to learning these products and tools.

Proteus has model for MMC. Is this going to work if I want the final design with SD?

Hello fagari!  Smiley

How did you make the image file (COUNTRY.TXT) into a Proteus MMC image (cardimage.mmc)? What program did you use? Please teach me how. Can I convert any text file into this image (cardimage.mmc)?

How about the reverse? I mean, when I want to convert the cardimage.mmc to a text file. Is this possible?

With WinHex you can read some sectors from your floppy or hard disk. I just save file to clean floppy and save some sectors from floppy to cardimage.mmc. Floppy has FAT16, hard disk FAT32.

Thanks for replying!  Smiley

Can I convert a certain file in my hard disk(for example sample.txt) into cardimage.mmc? How do I do this? There are many convert options in WinHex. Which one should I choose? Please teach me how. It's my first time to use WinHex.

Also, after manipulating the cardimage.mmc in Proteus using a PIC18F(with FAT32 implementation), can I bring it back to the text file format which can be understood by Windows? I am confused with this because I can't understand the data whenever I open cardimage.mmc with Wordpad or Winhex.

Hello incubus22

I use 32 MB SD Card and copy CONTRY.TXT in SD Card.
after make image file with WinHex.

if you don't have sd Card.

You can use 'USB Flash Disk Example' in the Protus 7.2

Hi fagari,

Here's a difference between both SD Image file, I explain:
You file (cardimage.mmc) is a FAT16 and the file (disk.bin) from Proteus sample is a FAT12.
Thus, if i try to use your file (cardimage.mmc) in the simulation, windows don't create a virtual "PROTEUS USB" mass storage... (btw: there's not source to change in FAT16 in Proteus sample directory).
I've not yet find another "Virtual USB Mass Storage" on the web! Sad
If you or anybody have a answer, it's welcom... Smiley

Regards,
Marineland

Hi Marineland

1. Copy 'cardimage.mmc'(in my project) file to 'Proteus 7 Professional\SAMPLES\VSM for USB\PICDEM FS USB\MSD' directory.

2. Open picdem 'fs usb.dsn' file with Proteus.

3. Right click on the MMC and select 'Edit Properties'.

4. Change Size of Media(MB) to 32 and Card Image File to 'cardimage.mmc' and press Ok.

5. Run simulation and plug usb connector.

6. You must see new removeble drive in my computer.


File read ok. but write and format have problem.

Hi Marineland again

Proteus sample file imformation :

The USB firmware used in this sample is freely available from the Microchip
Technologies website (Application Note  AN1003) and has not been modified.

AN1003 application support FAT16, FAT32 or NTFS file system.

Hi Fagari,

Thanks for the response...  Smiley
I'v followed yours instructions but the simulation failed:
This's the error: "Can't ceate or open card image file: cardimage.mmc"

What i'm doing wrong?  Huh

Hi Marineland,

My MSD Project is here.

Try this.

if your problem going on, try reinstall proteus.

Good luck.

Hi,

I'll try your project, because some time ago I tried to make a project with SD card and CCS libraries, but it didn't work at all

Thanks
