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

the security administrator does not actually solve the security issue. A new generation of firewalls should enhance the security of the release data, because the real demand for network security is to ensure security, but also to ensure the normal application. This article describes the Smart Firewall is a smarter, more intelligent firewall products, it overcomes the traditional firewall "one tube dead, on the chaos" situation, fixed the above firewa

is the Guest account used or not, is this a problem? By default, many Windows systems automatically turn off the Guest account's enabled state, and many users who value the system security will not hesitate to "hit the Killer" on the guest account and not allow it to start running, in the view of these users, as long as the guest account is opened, Then the Windows system encounter hacker attacks will be inevitable! In fact, as long as we manage the Guest account skillfully, we can enjoy the gue

In this article we use Photoshop to create a rusty metal tube effect.1. Start First create a new document with a canvas size of 450 x 450 pixels with a resolution of 72. Fill the background with a very dark color #111111. 2. Draw a rectangle Create a new layer and get a flat-width selection My selection is actually set to 22px, which adds color #5e5e5e to the selection. 3. Dodge Tools Basically, the tools you need are just dodge tools: Set

Commonly used pipes have steel pipe, steel corrugated pipe, 3 kinds of plastic pipe.The advantages of the steel pipe are easy to install, can be welded in the steel skeleton outside, may replace some of the steel section, and because of the rigidity of the steel pipe. After embedding can basically maintain its parallelism and flatness, many large-diameter cast-in-situ piles are used as pipe for sound measurement. But the price of steel pipe is more expensive:Steel corrugated pipe is a kind of go

But the drive circuit is to have a certain hardware basis (such as): such as 2 pieces of 74hc573. And I only have a few

The resistor is a resistive device with a non-linear volt-ampere characteristic, most of which is protected by voltage circuitry when the circuit is under overvoltage and absorbs excess current to protect the sensitive device. Usually called VDR. The resistor body material of the resistor is a semiconductor, so it is one of the semiconductor resistors.TVS (diodes), also called TVs Tubes , are widely used as a new type of efficient circuit protection device with fast reflection time and very high

In the beginning of no digital display, the sequence is a matrix keyboard, followed by the digital tube 0~f,6 simultaneously digitally controlled static display.Digital control and Matrix keyboardFirst of all, the selection of the digital tube is closed to let the digital tube display no matter what the number. Then select all the digital

First, the circuit compositionThe regulator circuit composed of Zener diode dz and current limiting resistor R is the simplest DC regulated power supply. Two basic relations can be obtained from the regulator circuit of the regulator tube : Ui=ur+uo Ir=idz+il Voltage Regulator Tube volt-ampere characteristics such as, in the voltage regulator circuit, as long as the regulator is always wor

the semaphore is 0, it enters the waiting queue.After exiting the critical section, use the V operation, the semaphore value plus 1, if the semaphore is also less than or equal to 0, then wake up a process in the waiting queue.II) Achieve condition synchronizationA thread A uses the P operation, a thread B uses the V operation, and the initial semaphore is set to 0. To satisfy a condition, thread A can be executed only after the execution of threads B. This can be achieved easily with semaphore

negative voltage VGS between the grid sources is applied, the two PN junctions in the junction field effect tube are in the inverse state. (b) is shown. with the negative increase of the VGS, the reverse bias voltage added to the PN junction increases, and the depletion layer widens. Because of the low doping concentration of N-channel, the depletion layer is mainly concentrated on the channel side. The depletion layer widens, making the channel narr

created a session for this customer. , the server will use the session ID to retrieve this session (if it is not retrieved, may create a new one, this situation may appear on the service side has deleted the user corresponding Session object, However, the user manually appends the previous jsession parameter to the requested URL. If a customer request does not contain SessionID, a session is created for this customer and a SessionID associated with this session is generated, and the session ID

This is a 3D simulation of Numerical Control Tube Bending Machine that I have been working on.Program. Currently, the entire program is written in C ++/CLI, and the interface is. net controls (the color must be consistent with the previous project, so it is ugly), the 3D part uses OSG for display, and the control uses managed C ++ for programming to interact with OSG. 3D Machine tools use SolidWorks for modeling and export to the formats supported by

Direct block transfer, that is, in the process of transferring a block of data between the memory and the I/O device, without any interference from the CPU, only need the CPU at the start of the process (that is, to send a "send a piece of data" to the device The process ends when the CPU polls or interrupts to see if the process is complete and the next operation is ready. The actual operation is done directly by the DMA hardware, and the CPU does something else during this transfer.Letter

instruction, as long as the instructions are taken out, you can immediately use the operand.Direct addressing: in the direct addressing, the Address Code field given in the instruction is the valid address of the operand, that is, the form address equals the valid address.indirection : Indirect addressing means that the address a given in the instruction is not the address of the operand, but rather the address of the primary cell that holds the operand address, or the address of the operand ad
