Help with proteus simulation for sd card

[anhnha]

I am doing fatfs sample for sd card. I have created and compiled the example successful but I cannot simulation in proteus.
In the library Mr Chan also provide a schematic for sd connection. I want to simulate this circuit by proteus but it is not work. I use atmega64 in this example. Can anyone kindly help me make a proteus file .DSN to run the example.
Bellow are schematic that Mr Chan provied and my hex file .HEX with mmc file .mmc for simulation.
(If you need more information, please let me know)

Could anyone help me? I did it but it doesn't work.
Maybe some suggestions?

Why don't you use mikroC Pro AVR?

Why don't you use mikroC Pro AVR?

I am not familiar with mikroC.
Now I am buiding sample provided by Mr ChaN. I compiled it well but when I simulation in proteus with the schematic above it doesn't work!
If the sample work then it is easy to adapt to my project!

 

[internetuser2k12]

I will check your project tomorrow. mikroC is nothing but C. It has Mmc and SPI library which you need for your project.

 

[anhnha]

Thank you,
In my attached file, there are only .HEX and .mmc file. Because my DSN is not work I don't send it.
Hope you can help me create a DSN in proteus with atmega64 like the picture above.
As for .HEX file it is a sample project therefore I think that it will work well.

 

[internetuser2k12]

It's OK. I will check you proteus design. send it.

I don't see any signals on pins SCK, MISO, MOSI, and SS.

I'm getting sick and tired of all these recommendations about microC and it might not cost you anything because you are using a "free" version (that is clear by now) but you either ask others to pay a bunch of money to buy the application without reason since winavr is free or you push them to follow your "free" path which is as bad.

Is WinAVR a compiler? I use only PIC and mikroC Pro PIC.

@alexan_e:

Please don't make requests for help in private using PM. Create a thread in the forum so that other members can benefit from the posted answers.

Thank for remind,
I get it now and will do it.
@internetuser2k12:

Yes, but I have send HEX file, now it is only need an DNS file.

 

[alexan_e]

WinAVR can be found **broken link removed** and can be use with AVR studio as a graphic IDE.
AVR studio 6 already includes its own spin of the GCC and tools

Well, this is a thread about a project using an AVR mcu so your recommendation was for mikroC Pro PIC ?

 

[bigdogguru]

What is really a shame in this case, there have been 8 replies concerning the choice of compiler, which has NOTHING to do with anhnha's original post.

I agree with Alex, why someone would choose to use an inferior compiler, IMHO, over a freely available and well supported version of GCC is beyond me.


However, back to the OP's question, I have found the following 4 part tutorial covers AVR SD/MCC interfacing and FAT quite well:

Simple FAT and SD Tutorial Part 1

The author, jokkebk, of the tutorial is actually a member of this forum.

Send the proteus .dsn file.

Physical drive nmuber

Bellow is DSN that I used. But this file is where my problem is!

For what clock frequency did you compiled the code for? Are you using ext or int oscillator?

 

[anhnha]

For what clock frequency did you compiled the code for?

It is 9216000Hz(but I think that it isn't matter in proteus)

Are you using ext or int oscillator?

No.

 

[internetuser2k12]

9.216 MHz? Compile the code for 8 MHz and zip and post the hex file. Is it external oscillator?

 

[anhnha]

It is system clock, F_CPU = 9.216 MHz.

 

[internetuser2k12]

I am asking Fosc? actual clock you are using

 

[anhnha]

Fosc = 9.216 MHz. This is a sample written for atmega64.
Here is an image about schematic. Fosc in this circuit is 9M216
