For such use It would be nice to have a free open source version....

Actually i was surprised no one did it so far. And with all the

Initially i thought that it wont be too hard. It is written in ANSI C. The low level MMC access library from CCS works fine. So i th ...

Hi everyone!

I was wondering if there is a port of FatFs for CCS out there ?

I'm trying to use FAT for MMC cards and nothing seems to work (direct spi ...

......I would get rid of ...... #zero_ram.....

THANK YOU ! Razz

It works and even in my original test program (with GLCD, PWM etc..)
and even with ADC_CLOCK_INTERNAL and 40 MHz Smile

Do you really have a crystal or oscillator that runs at that frequency ?
Yes I do. Exactly at this frequency.

Also I've just tried the :

Hi all again !

After some break I'm back to this project.
