Mr.Hans & Mr.Erik and all others helping me

Thanks for your advices and i would like to take it positively. I would like to mention that microcontroller was not a subject in my cource work nor I have gone any training in this field. I have started self study. My professor gives me maximum freedom to do it in anyone of 8051, 80196, PIC or even in uP. But it is my interest to do it in 8051 so that I can learn the basics of microcontroller programming and we purchased one 8051 CPU card and DAC card recently. I will be back after studying well the assembly codes. (To be frank, i feel that this is not a good forum for the beginners). Also, I have the midterm assessment and I want to prepare for it. I also have to finish some other parts of the project soon. Expecting your helps in future also.
regards,
Boby
