Provided that it has a usb HOST port; probably the majority of non-x86 systems that run linux or wince do not, though more that do are becoming available.

Have used their 8051 devices for several projects and their stuff just works out of the box. One project (400Hz pwm inverter) interrupt handler time, with 6 or so lines of c code, profiled at less than 50uS from start to finish... Regards, Chris

The simplest way to do that is "Vinculum". However it will take the eternity to copy from one flash drive to the other with the transfer rate of 200...300KB/s.

The hardware, despite offering options, is suprisingly easy to make work well. I kind of expected that I'd have to read tiny details spread all over the place to get something going, correctly. But it's been less work than I'd anticipated, beforehand. For example, in a case where I worried about track and hold sampling on the ADC, the options are both flexible as well as easy to fathom and use properly. I'm still waiting for the other shoe to drop. ;) Jon

I'm not seeming to find anything on their site with USB __host__ functionality, which part did you have in mind? |
