Hi to All !
I am searching for a sample code in order for me to be able to write and read data on sd_mmc cards using PIC micro.
Any sample code available ?
Any suggestion ?
Thanks in advance for the help .
regards

I haven't searched this site, but do remember seeing something about using MMC cards. However, this is one link I had bookmarked ... I haven't checked if it used Picbasic pro or not.

I'm just getting back into tinkering again. But if memory serves me right a SD card is basically a SPI interface. Now if you want the card to be read in a PC also, then things get a lot stickier.

Have a look at

www.jianpingusa.com

for a ready built solution. Runs with PBP at 19,200 bps.

I bought a pair and got them very promptly. They are to be used in my next project and not used just yet.

Jerson >> That compsys link only has a schematic. Do you have that Picbasic code? A link for the code is there, but it's dead or wrong, or something.

The code is still there - and it's downloadable. The link opens up a Directory, thereafter just click the file you want, BAS, HEX etc. I've had a quick look at the BAS file, and it is recognisable as PBP...

I do not want to read the sd mmc cards using the PC: i will like to read / write it just using the PIC . I will like to have a sample program in basic if any.
Any help is appreciated .
Yhanks

Thanks a lot Bruce for the program relevant to mmc read / write in basic for the PIC .
That is great : I am very happy about that.
I will try it ... and could be i will ask few other questions !
