:-/HOLA A TODOS ME ENCUENTRO TRABAJANDO CON EL MIKROC YA QUE CON CCS C COMPILER NO PUDE HACER FUNCIONAR EN FORMATO FAT.....
ACTUALMETE ME ENCUUENTRO TRABAJANDO CON CODIGO DEMO QUE TIENE LA PAGINA (
http://www.mikroe.com/zip/mmc-sd_board_examples.zip) LO COMPILE Y ME SALE FAT NO FOUND NO COMPRENDO PORQUE...... ALGUIEN QUE ME PUEDE DAR UNA MANO....... NO COMPRENDO DONDE PUEDE ESTAR EL ERROR LO HE INTENTADO MODIFICAR EL CODIGO Y TENGO EL MISMO ERROR ESPERO QUE ALGUIEN ME PUEDA AYUDAR EN ESTE FORO...

* Project name:
Mmc_Fat16_Write (Demonstration on usage of Mmc_Fat16 library)
* Copyright:
(c) MikroElektronika, 2005 - 2006
* Revision History:
20050512:
- initial release;
20051204:
- added test for file delete, to reflect changes in the mmc_fat16 library;
20060201:
- added test for swap file creation, to reflect changes in the
mmc_fat16 library;
* Description:
This project consists of several blocks that demonstrate 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;
- Reading file contents;
- Deleting file(s);
- Creating the swap file (see Help for details);
* Test configuration:
MCU: PIC18F452
Dev.Board: EasyPIC4
Oscillator: HS, 08.000 MHz
Ext. Modules: MMC/SD card on PORTC
SW: mikroC v6.2.1
* 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!
- This example expects MMC card to be inserted before reset, otherwise,
the FAT_ERROR message is displayed!!!
