multimedia card image file

Hi All,

I want to know how to make a .mmc image file to insert it in a proteus simualtion

Thanks
 

mmc image file

you can use WinHex software.

if you just want a blank MMC file (for simulation purpose),
you can create a blank text file, then just rename it, for example, to "blank.mmc"
 
proteus mmc

No I don't want it blank. I want to format .. store data .. and read it.

I didn't know how to use WinHex for that.Can you tell me how please ?
 

proteus mmc image

Hi everybody:
I want to connect a multimedia card (mmc) to atmega16 avr in proteus.Could anybody please tell me what "mmc image file" is ?
 

mmc card image file

mmc image file is the image file you want to load in the card

This code writes and reads data to and from Multimedia Card (MMC) in SPI mode.
The code has been written in ICC AVR


The schematic diagram of the above mentioned code drawn in Protues VSM is given below:

proteus mmc card image

Hello!

If you just want to write raw data on the MMC, the above code (posted by
yasir9909) will make it.
Now if you want to read it on a PC, then there are 2 solutions:
- Implement a file system (FAT16 or FAT32) on your microcontroller;
- Use dd (disk dump???, available here) to put the whole card contents
in a PC file.

proteus 7 multimedia memory card

You are right the above code works for writing raw data on the Multimedia card in
SPI mode.I have used that code to design a speech recorder.
I had recorded speech data on the card and then, on demand, it was transmitted to the PC through serial link.The speech data is saved through Hyper Terminal in a binary file.This binary file is then converted into the wav file for playing the sound recorded on the MMC and sent to the PC after being read from MMC.

Now i have plans for interfacing this MMC with Camera for capturing and storing images on the MMC.

Do you know whether this scheme would also work for storing images captured from camera on the MMC

proteus mmc simulation

Hello!

As long as you know what you write to the MMC, anything can work.
It will depend on the camera. Will you use a camera sensor and
some microcontroller (i.e. make your own digital camera)? In this case,
you can write whatever you want to the MMC.

Now if you want to do the opposite: use a regular camera to write a file
and then read this file from a microcontroller, then I guess you will have
to implement a FAT file system. Not very difficult, but it takes a while until
it works well.

And there is something one should be aware about before writing a FAT.
With small microcontrollers (with limited memory), it takes a while to update
the file tables once you wrote data. (FAT tables update, file record update).

mmc card image proteus

Which file system should be preferrably used i.e. FAT16 or FAT32.I havent worked on FAT system.

As far as i know this system is used in PC by windows and FAT stands for File Allocation Table.

Can you please tell a little bit detail about FAT in context of implementation on MMC

Hey gnem09!
I'm trying to generate a .mmc file with winhex but it doesn't work, becuase winhex generates .bin files, not .mmc
Can you tell help me? I really need to know how to generate this file!!

Hello!

What do you mean by ".mmc file"?
If you explain what exactly you want to do, you will increase your chances
of having a relevant reply.

Hey gnem09!
I'm trying to generate a .mmc file with winhex but it doesn't work, becuase winhex generates .bin files, not .mmc
Can you tell help me? I really need to know how to generate this file!!
 

any help about getting .mmc image file from a real sd card ..??
