vidicon tube

LED digital tube is widely used in single-chip microcomputer system, it is composed of light-emitting diode. The digital tube consists of 7 LEDs of a "day" shape, if the need to display the decimal point, then add a point, is a 8-segment digital tube.Digital tube Display high brightness, the corresponding speed, sub-common cathode and common anode two forms, comm

Does not accumulate Kuibu not even thousands of miles, does not accumulate the small flow not to become jianghai. The foundation is not strong, shake. I have no doubt that I will never feel guilty about wasting my time on simple things. Simple things to repeat, you are the expert.Repeat things with your heart and you are the winner. Experiment Static display Y6C is an election, y7c is De Shun.Another particularly important thing is that it is a co-Sun digital

Use 4*4 's matrix keyboard and a digital tubeEncode 0-f characters on the 4*4 matrix keyboard, and a digital tube to display the characters entered on each keyboard.4*4 keyboard Detection program, press the key after the corresponding code displayed in the digital tube #includeThis has a bug that every time you enter the digital tube is not empty but the reality

At the beginning, the digital tube is not displayed. After the matrix keyboard is pressed in sequence, 0 ~ F, six digital tubes are displayed statically at the same time. Digital tube and matrix keyboard First, disable the segment selection of all digital tubes so that the digital tubes do not display any numbers, and then select all digital tubes. Next, you only need to select all digital tubes, in the fut

1. Effect display2. Hardware devicesIn a treasure bought a 4-bit common yin digital tube. 4 Number of common one cathode, altogether 12 pins. One of the 6,8,9,12 is a common-yin pin.　　Each number consists of A-g 7 diodes and a point DP. Because it is bought online without detailed device manuals, you can only test the pin and the digital diode on the corresponding relationship.　　You can see that the number 12th pin corresponds to the first digit of th

system, introduce the concept of "process".Second, the tube processUse PV the mechanism of operation and semaphore solves the problem of synchronous description of the process, and the large amount of synchronous operation of single semaphore is not easy to manage in each process and can cause the system to generate deadlock. The concept of pipe process is introduced for this purpose. Enhancement is to keep all of the processes in sync with one resou

Widely used in electronic equipment led digital display data, in many applications also often analog LED digital tube display data, so that the program screen looks very distinctive. Using the Delphi program to realize the simulation of LED digital tube is very easy, the specific steps are as follows: 1. Start Delphi 4.0. In the Tools Tool menu, select the Delphi Image Editor "Image Editor", create a new b

For a 10-digit arrangement, to doTwo adjacent numbers can be made up of another number or minus a few strokes, but cannot be added or subtracted. For example, 7→3 is allowed, 7→2 not allowed. Arbitrarily enter a set of numbers to determine whether the above
