Digital tube connects the led lights above what is the meaning of

CodePudding user response:

LED1 ~ LED8 is line label, and P00 P07, VCC, GND etc on behalf of the electrical connections, search circuit diagram, there are other places have LED1 this label,

CodePudding user response:

LED1-8 digital tube, digital tube, which one is to choose light should be connected on a chip, abcdefg dp is a paragraph, which a few is lit digital tube to show different Numbers

CodePudding user response:

Ask LED1 to 8? Are you? Label that is network, SCM I/O port should have the same label, which is the dynamic digital tube display, COM is a total Yang (ground), single chip computer to a high level or low level of the digital tube will work

CodePudding user response:

refer to the second floor FBIIIC response:

LED1-8 digital tube, digital tube, which one is to choose light should be connected on a chip, abcdefg dp is segment, it is light which a few segment digital tube to display the different digital

I now want to simulate traffic lights, the question now is whether the digital tube a selected is p 2 mouth 2.3.4 but led lights and p 2 mouth, that the two can at the same time

CodePudding user response:

Actually only have even on such as P2.2 simultaneously, microcontroller is step by step operation, seems to be bright at the same time, it is the use of the human eye light

CodePudding user response:

Should be a common Yin/common anode
