Send a Video Stream to PC using VUSB

Post by sarim » Sat Mar 15, 2014 12:37 am

Is it possible to send a video stream from Atmega32 to pc using vusb ? I want to read a VGA signal using the builtin ADC and send that to pc. Do you think atmega32 and vusb is fast enough to do this in real time ? suppose a 640 x 480 vga signal will contain 3 byte (R,G,B) for each pixel. 640 x 480 x 3 = 921600 byte = 900 kilobyte. is it possible to send 900 kbps signal using vusb ?

No, V-USB only supports Low-Speed USB and even that only with limited throughtput. You will at least need a full-speed USB device for your requirements.

... and you will also need better ADC ... The ATMega ADC are not fast enough for such application.
