Hello I'm a student in intership and my project is to make a usb connection with the DE2 card !
LOOK:
PC (host) -----(usb in serial)---->(DE2, usb device(isp1362))
for Make this systeme I use
Labwindow/cvi fort send the data .
Quartus II Nios II and DE2 CARD with (a cyclone II)
IN the cd I use Cdrom of DE2 card
I use the demo Software for understand the functionning of the Universal serial bus !
this is a link with my project
http://files.filefront.com/pjt+usbzip/;13633905;/fileinfo.html Look the altera software Send 2 messages add and clear ADD !

ADD correspond to : ??????? that is the question :D
Clear correspond to : 0x55 or 0b 1010101
What is the variable of the data is stock ?
what is in the programme ISR.C ("in the link of the project"):
bD13flags.bits.DCP_state
bUSBCheck_Device_State.State_bits.RESET_BITS = 1;
bUSBCheck_Device_State.State_bits.FOUR_RESERVED_BITS=0xcc;
Is possible to explain to me the programme ISR.C please !!
In the globality my project is the to simulate the communication between the computer and one capteur Of ATLAS detector !
