Have anybody experimented with avr and usb?
I was thinking of using one of the ic´s from philips called PDIUSBD11D and PDIUSBD12D, they connect to the usb port on one side, and on the other they have an IIC (or I2C) interface, but so far I´m unexperienced with IIC, at least at the avr/software. I´m also a bit unsure about the PC software, do I use HID device? Is this hard to do?
I just want to send some bytes now and then from/to my circuit. Now I am using COM port, but one of the great stuff about USB is that it can supply 5v to the circuit.
I guess I could figure out the hardware stuff, but the software, both in the avr and the pc, will be more difficould.
Does anybody have assembler examples or anything that could get me on the way?
