I used to always USES is the total of the Yin, is to use 74 HC573 latches and 74 HC138 compiler to realize dynamic scanning,
The compiler data on 38, then, I now have the 8 bits of Yang digital tube, no matter how to adjust the data I digital tube is not to dynamic display, excuse me how modify realize, I appreciate!!!!!!!!!!!!!!!!!!!!!!!! Urgent for ~ ~ ~ ~
