#175104 - Problem sending data to host using Cypress FX2 |
I am using the cypress fx2 ezusb chip to implement HID Mouse.
Up till enumeration, everything is fine. Host(my PC) recognizes the cypress chip as Generic HID Mouse. But after that I am unable to send data using endpoint 1. I enabled and configured endpoint1 for interrupt transfer. After writing the report descriptor, I poll for Busy bit=0(indicates buffer is available) in the EP1INCS register. If it is zero, I write the data bytes to the EP1 buffer(EP1INBUF) and write the byte count to the EP1INBC register. This should arm the endpoint and transfer the data to the host. But I don't see anything being sent. I am using USblyzer to decode the USB port traffic. Any help? |
