okey here is the situation

- the hex file i downloaded from the internet is working both on 89c2051 and 89c51.

- the LED blinking program i wrote is working on 89c2051 but not on 89c51.


i think the my programmer is okey as well as the circuit.


Alfredo del Rio you was right in that.... LED should not be connected in that way. it was just a testing environment.
