Where are you, help me to look at the problem, use two displacement of 164 series, but after she moved to the D8, yao is a high level, but the second is on the tip of the 1, 2, 164 grey, data did not enter to the second 164, what reason?

CodePudding user response:

You are such a high level to enter the high level, so don't know,

CodePudding user response:

The D8 series resistance and proved

CodePudding user response:

Simulation, this circuit can actually really not a dead man, so at least LED to series current limiting resistor, secondly it is recommended to use total Yang connection, the cathode received 164 output, and finally recommend a better chip 74 hc595 are needed

CodePudding user response:

It seems every BBS have not understand electronic circuit simulation in their design and make the board, the problem is really strange, is the wizards, gild the lily, have mistakes, all kinds of strange circuit,
Anyway, if not familiar with electronic circuit, at least the consult familiar people, or learn some basic knowledge, to find and refer to some successful circuit, will dare to say that they go and play in the design of circuit board, otherwise, which come of the self-confidence, circuit can work properly according to the design intent?
