rectify this code to blink 2 leds with 555 timer.555 is connected with p3.7 of at89c2051.
that 555 is controlling externally the blinking rate.the 50k preset is connected with ne555. that preset is main controller to increase decrease of blinking speed.
actually i want to make a circuit like 4017 and 555.that 4017 is controlled by 555ic.
