Hi My friends.I apologize for my bad english first. my name is mustafa, Im from turkey.I need help for the MMC card project.Can you help me?
I'am edit the Mcro c code and runing on proteus file but I can not run when the circuit made. I do not know where I'm wrong. Please help me.Thank you vaey mach

you don't say what the problem is , only that it does not work
What part does not work ,is the pic running ? or you only get gibberish on the screen ?
be a little more clear on what is happening when your trying to run it

thenorthstar,

Your program runs just good as what you are writing for. Its just keep APPEND to a file, READ the ADC, WRITE to a file and delay for one second.

You don’t give your circuit and your program any other option; just reads ADC write to the file, delay and then repeat. Here is your loop:

            for(;Wink                      // sonsuz döngu
            {
            Rj2_bit  = 0;                // Turn ON LEDs on PORTJ
            mmc_fat_append();            //dosyanın sonuna ilave et
            sicakligi_oku();             //sicaklığı oku
            mmc_fat_write(sicaklik,9);   // sd karta yaz
            Rj2_bit  = 1;                // Turn ON LEDs on PORTJ
            UART1_Write_Line("TEMPERATURE DATA STORAGE");
            delay_ms(1000);              // 1 sn bekle
            }

I suggest:

You make a  continues loop and keep monitoring some input and response to the input. Let say you will have two input buttons, one for write and the other for read.

While(1)
{
   if(!button_1)   // USE ANY PORT PIN FOR INPUT1
   {
            Rj2_bit  = 0;                // Turn ON LEDs on PORTJ
            mmc_fat_append();            //dosyanın sonuna ilave et
            sicakligi_oku();             //sicaklığı oku
            mmc_fat_write(sicaklik,9);   // sd karta yaz
            Rj2_bit  = 1;                // Turn ON LEDs on PORTJ
            UART1_Write_Line("TEMPERATURE DATA STORAGE");
            delay_ms(100);              // 1 sn bekle
   }

   if(!button_2)    // USE ANY PORT PIN FOR INPUT2
   {
      --- DO THE READING AND DISPLAY ON LCD OR THE TERMINAL ---
      (Of course you need to prepare file name and read cmd)
   }      
}

Try to modify your circuit and program to see how it works.

Good luck,


Tom

well what can I add,
1. do you know if micro is running?  is led flashing? (xtal, config, wiring error)
2. any display on screen?                 is display Blank, Dots or what ever?
3. have you checked pic config is right?

Have you coded a board check program?

When I start a new project I program test code to test Display(hello world), Leds(flash leds at a timed rate) and Input devices(switch on leds via input pins)
And when board is working then go-on to project.

thenorthstar,

First I have to tell you that I don't have MikroC installed in my computer, and, I have not used MicKoC; so I can not write the program for you. I will help you with what I know (I am using MPLAB C18, C30 and C32).

I see you have implement one part of my suggestion that is the write button. I would like you to use READ button for reading the file and display the data on the terminal (use UART1_Write_Line()Wink.


   if(!button_2)    // USE ANY PORT PIN FOR INPUT2
   {
      --- DO THE READING AND DISPLAY ON LCD OR THE TERMINAL ---
      (Of course you need to prepare file name and read cmd)
      (you may have to close the open file and then reopen for read)
   }     



One of the thing I see is a problem when you define FILENAME:

char filename[]="SICAKLIKTXT";

I think you are using FAT16 and the filename is SHORT filename that is in the format of 8.3. You should change the filename to:

char filename[]="SICAKLIK.TXT";   // see the period

After change the filename, compile your file to see if it works.

I have a question for you:

How do you know if it is works or not? Do you read the MMC card by card reader?

As I said, you should use the READ BUTTON to read the file and display the data on the LCD or Hyperterminal. That way, you know if it is write the data to the MMC card.

Until then, I will check back later.

Regards,

Tom

bbarney,
yes brother threw mmc card format but still did not work.Sad

Posted on: May 06, 2010, 09:53:41 09:53 - Automerged

TomJackson69,

First I thank my brother and I 'm sorry for my english.
I read the MMC card by card reader but  When I look into the MMC card is empty.
I tried your suggestion, yes I'm using FAT16 and changed the filename to: char filename[]="SICAKLIK.TXT"; and I tried again but still did not work.

my brother, I ask, can you  write sample cod (read and write file in mmc card same my project) whit MPLAB C18  for me? Sad

thenorthstar,

Try to close the openned file before you read it.

Change your while loop to a for loop to write 10 ADC samples enthen close the file:

        while (1)
         {
              if (Button(&PORTB, 1, 2, 0)) {  // write Button
            RD3_bit  = 0;
            Rj2_bit  = 0;                // Turn ON LEDs on PORTJ
            mmc_fat_append();            //dosyany'n sonuna ilave et
            sicakligi_oku();             //Read tempareture
            mmc_fat_write(sicaklik,9);   // write in MMC card
            Rj2_bit  = 1;                // Turn ON LEDs on PORTJ
            UART1_Write_Line("TEMPERATURE DATA STORAGE");
            delay_ms(100);              // wait 1 ms
             }

        } //while (1);

change to:

        for(i = 0; i <= 10; i++)
         {
              //if (Button(&PORTB, 1, 2, 0))
             //{  // write Button
                  RD3_bit  = 0;
                  Rj2_bit  = 0;                        // Turn ON LEDs on PORTJ
                  mmc_fat_append();             //dosyany'n sonuna ilave et
                  sicakligi_oku();                    //Read tempareture
                  mmc_fat_write(sicaklik,9);   // write in MMC card
                  Rj2_bit  = 1;                        // Turn ON LEDs on PORTJ
                 UART1_Write_Line("TEMPERATURE DATA STORAGE");
                 delay_ms(300);                    // wait 300 ms so you can see the LED blink
            // }
        }

After write 10 sample, close the file.

//===========================//

thenorthstar,

For writting an example for you -->> the answer is NO <<--. It is not good for you because you will not learn. On the other hand, this is your project, you should spend lot of time to research and practice so you can learn from it. I can point you to the right direction so that you can complete your project.

And here is a link to the example from MikroC:

http://www.mikroe.com/eng/product_downloads/download/

Download the "BIGPIC5 mikroC Examples [147.74KB] ", you will se one example for the MMC. In fact, below is the copy:

 * Project name:
     MMC_FAT16_Test (Demonstration on usage of MMC_FAT16 library)
 * Copyright:
     (c) MikroElektronika, 2005-2008
 * Description:
     This project consists of several blocks that demonstrat various aspects of
     usage of the MMC_FAT16 library. These are:
     - Creation of new file and writing down to it;
     - Opening existing file and re-writing it (writing from start-of-file);
     - Opening existing file and appending data to it (writing from end-of-file);
     - Opening a file and reading data from it (sending it to USART terminal);
     - Creating and modifying several files at once;
 * Test configuration:
     MCU:             PIC18F8520
     Dev.Board:       BIGPIC5
     Oscillator:      HS, 10.000 MHz
     Ext. Modules:    MMC/SD card
     SW:              mikroC v.8.1
 * NOTES:
     - Please make sure that MMC card is properly formatted (to FAT16 or just FAT)
       before testing it on this example!
     - The MMC uses hardware SPI for communication, so make sure that it gets
       properly connected to the port where SPI module is located (PORTC for most
       PICs)!
     - This library is for PIC18 MCUs only!

Don't try to find the short cut to learn, you will forget very quickly.

I suggest you to use this example and experiment with all the option until it works.

***--- remember in this example the 10MHz crystal is used ---***

Also, when you initialize the MMC with:

Spi_Init_Advanced(MASTER_OSC_DIV64, DATA_SAMPLE_MIDDLE, CLK_IDLE_LOW, LOW_2_HIGH);

Pay attention to the "MASTER_OSC_DIV64" --->>> this is for 10MHz (you use 20MHz)

and where is your buffer? I see in the example hey used: char Buffer[512]; (I think the sector is 512 bytes). When write, I think you need to specify which sector to write to (may be in MikroC is different).

Here is an importance note from MikroC:
"
   - Please make sure that MMC card is properly formatted (to FAT16 or just FAT)
       before testing it on this example
!

    - The MMC uses hardware SPI for communication, so make sure that it gets
       properly connected to the port where SPI module is located (PORTC for most
       PICs)!
"
Good luck,

Tom

thenorthstar,

After take a closer look at the example program, I found I have make a mistake when I suggested you to change the file name from "SICAKLIKTXT" to "SICAKLIK.TXT". Please change it back to your original filename. In C18, the file name use "8.3" format. Sorry for that.

Anyways, the example program from MikroC should work.

Regards,

Tom

you can use M25P128   -   128Mbit Serial Flash Memory With 50MHz Interface
is more easy

hello:
I'm trying a similar project, and I like to simulate it first with proteus. the problem is that I don't know how to get a formatted image for the MMC, I used winhex to create an empty raw 32MB MMC image file (named cardimage.mmc), but how to get it formatted, I didn't found such a option in winhex.
I'm really stuck, please help.

thanks in advance

garbriel,

Go to "C:\Program Files\Labcenter Electronics\Proteus 7 Professional\SAMPLES\VSM for USB\PICDEM FS USB\MSD" copy the "disk.bin" to your project folder and use it as the disk image for your MMC card.
