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.
I can see that you don't believe in giving all information at the same time.
Your original post discusses control of stepper motors based on information from a keyboard. This is a trivial task for most processors.
Suddenly you start to mention transmitting video data through the processor. And in the next post, you have four video signals.
Unless you find a C51 variant with a nice hardware video module integrated, you should look for a different processor - something with good DSP support.
On the other hand - you have not mentioned if the cameras sends out analog video, or if they contain compression logic so that the video data has already been digitized and compressed.
Always make sure that your posts contain all relevant information.
Cypress EZ-USB FX2LP has 8051 core, and it provides Hi-speed USB connection to the external video processing hardware, like FPGA.
The OP wanted to use a 89s51, so no built-in video hardware is available...
It is the answer for the OP's question, "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."
