USB stands for ''Universal Serial Bus''. See http://www.usb.org/ for information about USB. [Tom Wilkason] seems to be successful teaching Tcl to send data through USB ports [http://groups.google.com/group/comp.lang.tcl/browse_frm/thread/9d1dd9f51893a4e0/73d89995525a8803], as was [Uwe Klein], with a [SWIG]ified libusb ... [UK] the [google] newslink leads me down a dark alley;-?. I've put a swig of my libusb effort on the net: http://home.foni.net/~kuttersegeln/swig_libusb-20050616.tgz ---- "Integrating USB into Products" [http://www.ddj.com/dept/architect/196700803?cid=RSSfeed_DDJ_All] ---- [AMG]: http://www.dlpdesign.com/usb/usb245.shtml is an outstanding product. On my first project using it I had a ''supremely'' easy time interfacing it with both the circuit (eight-bit FIFO) and the computer (Tcl opening a MS-Windows COM1:-type device). I highly recommend it. See also [Serial Port] for an opportunity to access USB via a virtual com port (VCP) driver. -- [RJM] [slebetman] Using the VCP driver for the FT245 on Windows I managed to push around 840kb/s from Tcl. The limiting factor appears to be the recieving end which is a small microcontroller with a 5MHz instruction cycle. Tcl's I/O is very fast! ---- [[ [Category Glossary] ]]
