I am using an LPC1769 on a PCB with a USB port. For the USB, I use the USB stack that came with Red Suite 4, RDB1768cmsis_usbstack.
Our device is being polled over USB by a master device, and should respond as fast as possible to such requests. At the moment, I have a main loop running at 100 Hz, which polls the USB port to see if a request has arrived, and sends an appropriate answer if so. However, I would like to service requests faster => is there any interrupt that is triggered when new characters come in over USB that I could use for this?
