#105908 - Microcontroller Problem when touched |
I discovered a strange problem with some none 8052 microcontrollers (never tried it with 8052). The circuit works fine, but once I put my finger over the plastic package of the microcontroller it hangs up. Once my finger is removed it works fine again.
Solution: I stuck adhesive metal tape on top of the IC and connected it to ground, this seems to have solved the problem. One possibility I ruled out which is I don't have special radiation in my finger because made my friends try it with their fingers, same problem. Can you explain this? Mahmood |
