I'm looking for code that interfaces 6 MMC/SD CARDs on the big8051. On ports 1-7. I need code for the board and the application for the host computer. I would like to program the host in c# using visual studio 2013. any code to start would be appreciated. Thank you for your time.

hi,
I need code for copying a file from SD card to USB stick.
both devices will be formatted to FAT32.
File size might be from several bytes to 300K.
the preferred solution will be a function that will block the application until it accomplish the copying.
instead a solution that requires periodically calling a service function is also acceptable.
I can even make the story simpler: instead of reading the data from the SD (something that I succeeded to do) the service will get a pointer to a buffer containing the data that should be stored on the USB.
this means that i might be that in order to copy the whole file several adjacent calls should be launched ( depending on source file size an buffer size), but in this case the adjacent calls should append the data to the USB.
please remember that we already are using the FAT32_Init() function for accessing the SD card.
If you have such code fragment and willing to make the changes to fit my needs please contact me.
Payment for this service will be

hi
I'm trying to get an RS232 click board working with a clicker2 board using microbasic.
My code is as as below. I don't get anything out of the serial port. It's just a very simple program to start with to get the 232 click working before I move onto more complex code. Within the code I also have a bit of code to turn on an led when a button is pressed and that all works OK. It's probably something very simple that I've not done but I can't spot it. Have looked at rs232 click examples and can't see what I am missing
Thanks
Paul

HI every body
I would like to generate two PWM signals from different channels and with phase shift between them (time delay),
I use PIC32MX795f512l , developing kit EASY PIC 7 FUSION , MikroC Compiler .

Hi everyone - great site!
I have an Intel Edison board which runs Linux (somewhat similar to a raspberry pi) I was able to install all the packages and libraries and it seems to run the command line aplay XYZfile.mp3 just fine (but of course, I can't hear anything as of yet).
So from what I understand, I still need to connect my Edison to an mp3 sound card such as MP3 Click that can receive that XYZfile.mp3 and play it/send it to speakers? I am correct in these assumptions?
If yes, could you please guide me on how to hookup the MP3 Click board to my Edison breakout board? FYI, my breakout board has been level shifted to 3.3v on all pins.
For more info on the Intel Edison breakout board, here is the link for the schematics and pin diagram information:

I really REALLY thank you anyone that can guide me to the right direction.
Regards
Flavio
