thank you mister T ,
but i really want to go with USB .
i have been to the page before but i cant find microchip among supported manufacturers.
think i should go through the page once more
 
i have been through this site . and was bout to tell you . this project uses dll and sort of things . apart from using the visa object. and there is not much of explanation . any way thanks for the effort . i will come back only after reading those materials
 
USB is a complicated thing.. you need to study how the communication works and how Matlab can communicate through USB. Study the material and maybe contact Matlab support or the guy who wrote the blog I linked.
.. as I said.. I would go with USART. You can get that working in an hour. USB can take you weeks of full time studying.
 
Ok.. I found this: **broken link removed**
If you really want to go with USB, then you need to find out how to setup your PIC as HID device. I hope microchip has some examples (code) for HID devices.
This is maybe the easiest way to get USB communication working.

The drivers I linked are not free.. you can search for free HID drivers for matlab or write your own drivers.. But, if you can afford Matlab then 69 euros for the drivers probably are not a problem.
