when i disconnect the serial port from the computer,this problem never comes again
Yes, problems are rarely what they seem, you were "certain" that it was the power supply. Congratulations on another experience gained. As to the actual problem, if you make sure your PC and uC board are connected to the same ground, the problem "should" disappear. If same ground is not available or does not solve the problem, use optoisolators. Erik |
