Does anyone have a schematic and example code for interfacing a MSP430 to the USB? I want the microcontroller to controll some basic I/O and communicate it back to the computer using USB. I could use serial interface, but it just is too slow.

Hi Greg

I have used DLP-USB245M with MSP430F149 and woks great...

At device productor home page you can dowload PC drivers.

The chip is nice! But at $25 a shot, it's way more expensive then the microcontroller.... Darn... I was hoping there was a cheaper way of using the microcontroller directly...

In any case, I didn't realize that there can be up to 1ms of delay before a host can start transmitting data on the USB! I need a method that can guarantee reception of data within 100uS maximum... Maybe serial method is the only way, without building a PCI board directly....
