Look at the code, define four use? To say the shrimps?Nickname is reminds me of the classical poetry: luminous wine glass, wine to drink immediately pipa rush, ZuiWo battlefield MoXiao, ancient in several people back,

LED small light circuit diagram
We can learn to control pin P0.0 after 74 hc245 control DB0, P0.1 control
DB1... P0.7 control DB7, we also learn a byte is eight, if we write a P0, it represents the P0.0
To all P0.7 8 bits, such as we write P0=0 xfe; Is converted to binary 0 b11111110, so light LED small lights program,

If you ask is P1 mouth on the definition of the word, useless, you light water control in P0 mouth, if your program has reached to the effect, then remove P1 on definition, still can use,CodePudding user response:
