Hi all,
i've been working on usb tech on xmc4500 board.
i downloaded example code from dave tool.
in that code i want to implement multiple packet transfer mechanism.
i;ve theoritical idea on this mechanism but dont know how to implement it practically.

from downloaded code, endpoint maxpacketsize is 64bytes.and allocating memory for those endpoints dynamically.
do i need to change the endpoint size to 512 (not in descriptors)if i want to send that much of bytes.
could anyone help me.i;ve been beating my head since 2days about this concept.
