I am doing a PC based oscilloscope, with usb interface, of 2mhz analog bandwidth..
we are using a 20msps adc from ti.ADS805E.
I have a difficulty in choosing the right microcontroller.. is it advisable to use a usb based microcontroller like microchip's pic18f4550 or use a "usb to serial (virtual com port) converter ic tusb83410"?? which is easier? or TUSB6250 USB to ATA/ATAPI bridge.?
or is there any other possibility?
pl reply..
thanx in advance,

See this CCS example file:

Also do a search with Google for projects. Use this search string:
That's a really good stuff! Thanks for the info, PCM programmer

EX_USB_SCOPE.C

Our company made a measurement device that uses a USB connection.
I have modified EX_USB_SCOPE.C from the CCSC compiler we have bought
It works well so far.
Now we have to connect more than one device at the same PC.
When we connect two devices they are all recognized as ID 0 so PC
application can connect only one of them.
I have to connect more than one device.
I think I have to change some constant in USB_DESC_SCOPE.H.
Could you give me some idea?
