Two digital tube pin definition is how to define?
CodePudding user response:
Digital tube with common cathode and anode and their driving circuit is different, and use it every time you should pay attention to distinguish, below is the two digital tube pin definition
CodePudding user response:
Eight data, two optional mouth (public)

, the vague shall specify what kind of single chip microcomputer, pin is hardware or software defined? See above speculation this reference: https://blog.csdn.net/xianfajushi/article/details/85511846 CodePudding user response:
Period and the definition of the won't know until you see how circuit connection to define, At least provide a circuit diagram or mimic diagram! CodePudding user response:
The refer to the original poster weixin_44745100 response: two digital tube pin definition is how to define? Two wires used to control digital tube choice, is to choose which start from digital tube display data, eight thread is used to control the digital tube display pin, is to control the digital tube display shows what Numbers or letters CodePudding user response:
Generally use two pins driver +, with eight other pin drive a ~ h; Need programming scan display (a1 ~ h1, a2 - h2 corresponding feet parallel) If your pin is enough, two are can be received is the power and a1 ~ eight h1 by one mouth, a2 - h2 pick another eight mouth Note: either way a ~ h need concatenated current-limiting resistor
