Hello Sir, I work on one project in which i control stepper through PC.I done programming in turbo C. Now I want to used Microcontroller 89s51. i want to make programmer using parallel port & communicate using USB port.
I want to programming suppose in keil.Keil is new for me.My requiredment is i done calculation for speed control in my turbo C program,i also give the keyboard input to my turbo C program. This input is go to microcontroller though USB port.
Is it possible that many thing is done in keil programming?
Thank you.
Why send the video signal through the C51 processor? The processor is badly suited for on-the-fly video compression/decompression or image analysis.
Hi, So, What is the other option for that ?. Because I want to control stepper motors & 4 video signal with Single USB port of my Computer.
Thank you for help me...
"I want to control stepper motors & 4 video signal with Single USB port"
So the big question is, how did you intend to send four video signals down a single USB link?! Relative to that, controlling a couple of stepper motors is a trivial task!!

You definitely won't do that on an 8051 alone! You would at least need dedicated video processing hardware, with the 8051 merely performing the control functions.
"So the big question is, how did you intend to send four video signals down a single USB link?!"
UVC (USB Video Class) spec supports multiple video streaming interfaces on a single USB device. Then, theoretically, a single USB link can carry four video streams. But I didn't examine it on Windows. :-)
Cypress EZ-USB FX2LP has 8051 core, and it provides Hi-speed USB connection to the external video processing hardware, like FPGA.
Anyway, it is never a beginner's project.
