pic18f6620 and ex_fat.c |

Hi all. I am currently trying to simulate a part of my work on isis proteus. It consists of pic 18f6620 and mmc card. I am using ccs for programming the pic. I tried the example that came with ccs, that is, the ex_fat.c example, but though there are no errors in initializing, i tried to use the 'format size' of the code but it just stops at 'Formatting size' and doesn't give either 'error' or 'ok'. Please any suggestions would be appreciated. Thank you. |

Yes.
Throw ISIS away.
Read what others think of ISIS/Proteus
Read the forum guidelines.
Use real hardware only.

You'll never, EVER get it to 'work' as a simulation using ISIS/Proteus.
Cannot be done.
Period.
As to why the simulation doesn't work (and never will) post your schematic. Unless you have correct level translation betwen the 5 volt PIC and the 3 volt MEM card, it can't work in 'simulation' let alone real life.
Please follow Mike W's suggestion...get real hardware then we can really help you.

Bottom line..In 'simulation' it never works..in real life it does !

Ok. I just wanted to be sure it works. I have read deeply about the power supplies pic and mmc and I am using a 3.3v pic(i.e LF). I would work on the hardware since this code have been proven to work. Thank you very much for your help. |

Funny thing is, a couple of years ago one of my customers implemented my file system driver on proteus. I told him not to waste his time, it did not have a hope of working. I had to eat humble pie because he got it to work well.
Just goes to show, you never can tell. _________________ Regards, Andrew
