Why don't you try keils A51 assembler!
Download the entire IDE, I think. It will help you.

Where are these port pins connected? If you have connected them to some circuit, first remove the connection and check the waveform.
Does it work on Emulator or Simulator?
Agreed, so post your schematics and code.

Hi, see for serial comm functions in any VB book. You will get few serial comm utilities while searching also. See this one

isp at89s52 flash programer circuit
It is not hardware but the software which checks for the connected IC and to program it. First of all any programmer checks for the checksum and then decide the program memory. Each of these ICs have a unique checksum so as to distinguish the program memory...
atmel baudrate calculator
Hi Wek, this SMOD - 1 is from the assumption
It is given that on reset it is cleared, so by default it is 0. But the red note is a precaution for Maverickmax

maximum baud rate for at89c51
Yes you are right. But closer not precise.
The baudrate coming is 4,464.29 * 2 = 8928.58
And you want 9600!
Why are you using 12MHz crystal? I will recomend you to use 11.0592MHz crystal. It will give you an exact baudrate.
Use the following formula if SMOD = 1...
Re: need some help
It is simple and possible. It is not clear that you want to rotate them in both the directions.
Assuming the simple unidirection control.
1. You need four port pins of microcontroller to control the on and off of motors. 2. Use MOSFET switches to switch on or off the...
Re: Hyperterminal
Have you checked the setup for serial communication?
8 bit data, no parity bit, 1 stop bit etc.
Is it matching? Becausse I simulated your code on Keil and is working fine.
Whether your LED blinks?, Increase the delay.
Or you can change the program by simply removing the...
