No matter how many lights, there will be this problem for a long time, sometimes it will be particularly obvious, and there is no regulation in what position, even if the machine is placed first, it will be so. Why? Even if the 75176 is changed, so will it be that the frequency error of the crystal is a little big, or is there a comparative error in the parameters of the components on the hardware circuit? Big brother, little brother, please, this problem bothers me for a long time! This time!
