#148652 - changing the polarity helps Responding to: ???'s previous message |
the brightness of the LED is not an issue anymore. but there is another problem tht has popped up. the LED stops blinking at random. sometimes the blinking stops when the port is high and at other times when it is low. i am using an 12 MHz crystal for AT89S52.any suggestions??? |
