thanks guys for your help.
i do need to read the RAM exist inside the microcontroller,my question is how can i do that ?? do you have any softwear can do that or anything?
thanks
RAM ?? If the 52 is programmed by somebody else and if you cannot change the code inside, you can't read it. The ram memory inside microcontrollers cannot be read otherwise than with the code inside the controller, only if that microcontroller have special functions implemented, like in-system-debugging (one example would be ubicom sx family). On the other hand, if you made the program in the uC or you can modify it (assuming you have sources), it's not so hard to read locations and send them to serial port for example.
