In order to make this experiment more obvious, I will use the serial interrupt, in the interrupt service program to read the serial number input, and then display the value on the digital tube. First, the digital tube configuration Before carrying out this experiment, we need to use the digital tube for the display of the experimental results, first of all, we re

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

Power supply design, or driving circuit, it is inevitable to use the field effect tube, that is, what people often sayMos. Mos have many types and functions. For power supply or driver use, of course, it is to use its switch function. Regardless of the n-type or p-type MOs, the working principle is essentially the same. Mos are the voltage added to the gate at the input end to control the leakage current at the output end. Mos are voltage controlle

Description: Liquid crystal digital Tube Seven number of figures in the number of Allah, the horizontal and vertical a short stroke is called a pen, that is, 7 has 3 pens, 8 have 7 pens and so on. 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

This morning, I looked at Facebook's old news about one person managing 20,000 servers. is also idle oneself probably to forget a bit. It is calculated by using the 1U server for all of the Facebook servers. A standard cabinet probably puts 20 units (ideally, no network devices, no storage). A total of 1000 enclosures are required for 20,000 services. Also find a news about IDC (Century interconnection is very good in IDC, take it as an example.)

Method for obtaining pipe standard and tube outer diameter The pipe standards determine whether the defaultpipe field exists in the second flasys. If yes, the data in cadpipe is obtained. The uniqueness of defaultpipe is determined by the flasys drop-down list. If "with metric tube" is true, replace the HGA obtained in defaultpipe with HGB. If defaultpipe is PP, take the A1A field in cadflang

I bought a 7-segment LED digital tube with ten pins, but the pins are not on the upper and lower sides, they are on both sides of the left and right. Best reference answer:Use a digital multimeter for pin-by-pin testing. Generally, the 10 pins are 7 segments and two public segments plus one decimal point.The public end is generally in the middle or at the most side, two rows, one row and one symmetric. You can sort other pins by yourself.Assume t
