89s51 usb programmer

Hi ajay & shyam,
As i explain early my project, i done programmer using pc parallel port & i want to do communication using USB.So i used USB to serial dongle for communication.
But now as per our requiredment we required 3.5 Mbps to 4 Mbps data trasfer speed of microcontroller in communication mode(Run time mode).So i try to find out other solution for that.I also try on other microcontroller.

Thank you.

:mad
what is the final application?

Sorry ajay,
This change is done today only. So i also little bit confused in it. But my project is same i done programmer using pc parallel port & i want to do communication using USB port.
I try to get this problem solution.

Thank you.
Again sorry for that.

ok.. there is one solution.. use IC with integrated Full Speed USB port. you can achieve up to 12Mbps of data transfer rate. hope this will help!

Hi ajay,
I search on that.I get Atmel ic AT83C5134 which speed upto 12 Mbps as datasheet.But from programming view it also new for me. In which also lot many things given.i read it.But i not sure for that.I send the link for that ic.

its good controller.. use it.. will wait for your next input..

Hi ajay,
I try as much as possible.I also required some guidence from you also.Because you give the proper guidense.

Thank you..

always here addy.. do not worry!

Hi ajay,
I think addy also face problem related to this.I collect information about IC AT83C5134. I have some doubt related to this in which also programming done in Keil C or/and assembly.But as i mention early to control stepper motor i want ot enter input data externaly through USB port.Is it possible in this microcontroller??..

Thank you..

well.. you need to make an interface and also need to find out how to write drivers for this IC. check application notes see if you can get some information. I am also looking on my side..
