Use the USB without using interrupt.

Hello,

I am now using the TI's USB example "usb_dev_serial" for 28075. Of course TI's code is good and I can run it successfully on my board. But I still have a question, is it possible if I want to use this USB function without using the interrupt? If it is possible, how should I modify the code?

Anybody can give me some advises?

Best regards.

    Hi Lam,

    You should be able to implement the same without interrupts. You'll have to use the polling method for frequently monitoring transmit and receive registers for new data. Again, for periodic polling you'll require atleast a CPUtimer or epwm timer.
