Re: [Fx2lib-devel] cheap fx2 hardware?

Yes, agree 100% to bad these other parts don't come with high speed usb...  The only ones I now of are high speed FX2, Atmel new Cortex and high end ARM parts.  It is hard to find microcontrollers with high speed usb.

Hi, Tim,

Thanks for the info. I already have the ezusb/fx in the keyspan serial adapter for full speed stuff.

The nice thing about the fx2 is its speed. I was able to keep up with a high speed/ high bandwidth iso stream which sends/receives 3 1024 byte packets in a microframe  (24Mbyte per second iso). It also was able to transfer bulk at 45Mbytes/sec - limited by the host speed - it issued no NAKs.  Also the downloadability of the ram based fx2 makes it a natural for a test type of device. Another nice feature is it can be forced into full speed, for even more flexibility in testing.

Regards, Steve
