#185004 - Parallel IO from USB Responding to: ???'s previous message |
Andy Neil said:
Wouldn't it make more sense to use a serial port (either a "real" COM port, or a USB "virtual" one) and an 8051 as an external "IO controller"...? FTDI (possibly also others) make chips & modules which can give you parallel IO direct from USB. For an out-of-date example, see: http://www.antronics.co.uk/usbmod2/ The Current range of FTDI modules is here: http://www.ftdichip.com/Products/...odules.htm - you want the ones with the "FIFO" interface. See also: http://www.ftdichip.com/Products/...odules.htm One big advantage of USB is that it is specifically designed to supply power to the device - something which neither RS232 nor an LPT port is designed to do. |
