i dont want to use any chip, only the PICmicro and the MMC or SD connected directly to it.

HI my friend
Then you can use mikrobasic library with  MMC samles and PIC18FXX
is very easy use....
only need  MMC, PIC18 , and compiler

Multi Media Card Library
The Multi Media Card (MMC) is a flash memory card standard. MMC cards are currently available in sizes up to and including 1 GB, and are used in cell phones, mp3 players, digital cameras, and PDA’s.

mikroBasic provides a library for accessing data on Multi Media Card via SPI communication.This library also supports SD(Secure Digital) memory cards

Hmm , very interesting Topic.
On one application I ended myself buying a Alfat chip based device. US$ 39.-

Did ALL tests with MikroBasic and MikroC , no luck !! It seems that the libraries are very sensitive upon the brand of the card you use.  Sorry about that. I even broke an brand new A-DATA 512 Mb MMC card ( no longer could format ) .  Sector access works good but no FAT handling...

I am not an expert , maybe my circuits have errors ??    ,... but if sector access works ,..... hmmm. Don t know for sure.

On the other hand , look on Proton`s Forums , they already have developed a set of MACROS that will handle FAT access on MMC cards BUT -------> you will need last version of the Software to handle the macro extension..... sorry again.

 

I second very strongly : get yourself an ALFAT or similar chip artifact....

Just to document the topic a little bit.

So long
