Getting Parallel Data from USB? - Electronic Circuits Projects Diagrams Free

nirmaldev · 15th October 2009, 06:06 AM

We have this project on an object tracking robot. It uses an onboard webcam to take images, which are sent to a computer and processed in Matlab to identify the target position and the computer generates the control signals for the movement of the robot.
The problem is that there is no parallel port in our laptop. So we are thinking of sending the data to the usb port and then somehow making it parallel data. When i googled "usb to parallel", i could see that many usb to parallel port converters are available. Id like to know if we can use those converters? Or is there a simpler method to convert the serial data from usb to parallel?
Thanks

use FTDI chip

example: FT245BM

or if that's complex for you, get a ready made FTDI module

example: UM245R DIP Module

yes there are plenty of USB to Serial adapters available. Recently I bought such an adapter called HL USB-RS232. I think thats a chines brand. I'd not recommend you to buy that because I'm still experiencing difficulties using that with Windows HyperTerminal. Sometimes it works perfectly but sometimes not

Used it with a custom C# app and it worked fine.
