RS232 Simulation?

I think you should give me all the explanation of what peripherals you are going to use in your project.. and possibly send a circuit diagram because without that you cannot program.
for now just send me list of peripherals like motor, 7-seg etc whatever u are going to use.

the project is as i explained in my first message.
It doesnt matter what microcontroller i use but i have to show the program coded in tasm.
This program should work in Dos and it should control a dc motor and a 7seg control via rs232. And it should include 2 push buttons for speed adjustion.
It is really important because i m dealing with my other exams in these days.Thanks for your attention.

so you have two push buttons, one 7-segment and one DC-Motor. Use of buttons is to change speed.. is it? and rs232 also do the same?

Please explain the use of switch and rs232.. are you going to use then together or u want to use them differently like two different programs. I hope you have already gone through the PWM code.. and code you posted before is a good start..

Just make a flowchart how you want your peripherals to work only then you will be able to program. decide how your final thing will work.. and make flowchart on that.

what do you suggest for peripherals?

i will not use buttons to change speed. Everything must be controlled by keyboard and the asm program.

actually i m mixed up.
should i use microcontroller? or can everything be controlled from rs232?
i dont know enough information to finish this thing.

well.. use anything you want.. will be simple to do if you use RS232.. just receive and then and do work.. if you use RS232 then there will be no need of button.
just receive a character from serial port and act upon the command..

hmm..

you already have the code for starting and stopping a motor.. all you need is to control speed now i am sure its not difficult for you as you already have the PWM code.

the problem is i m not familer with tasm and there is no more sources or i couldnt find any.

i can do anything in C, at least i can search but in asm and electronics i m limited.

hmm.. so why dont you do it in C? everything is same in C as you do in asm.. just small differences..
ok write start and stop of motor in C PWM i will explain..
