I have written a complete 8052 program, and i simulated it, and it works perfectly (it's around 6k).
This is until i do it with the hardware. I put the program into the chip, run it,.. then in a specific section of the code, when the running reached this part, the program crashes, the screen disappears and comes back again but with the program resetted. With the simulation (Proteous Lite) everything is perfect, and this type of crashing comes when you push something and forget to pop it.. but i rechecked this and it isnt from the stack. I don't know where its from. The thing on my mind is that the simulator is 8051 and im using an 8052 chip, but my professor says that the 8052 IS the 8051 but with little extra features so that shouldnt be a problem.

If anyone has passed through a problem like that, then please help me.. im new to 8052.


-THANK YOU!
