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

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
