The last time we used AutoResetEvent to implement a production/consumer queue. This time we will use the Wait and Pulse methods to implement a more powerful version, which allows multiple consumers, each running in their own thread. We use arrays to track threads. Thread [] _ workers; Through the tracking thread, we can end our queue tasks after all threads are finished. Every consumer thread executes a method called Consume. In a for loop, we can cre

so that they can be used for javafx. It is also responsible for thread-related rules and event processing. Glass wing Toolkit In the middle of Figure 1, the glass drawing wing toolkit provides local operation services, such as management windows, timers, and appearances. It provides services to connect to the javafx platform and local operating systems. The glass Toolkit can also process event queues. Unlike AWT, it not only manages its own event queue, but also local operating system events.

Procedure 5, 6: Pull down the bus 5us, then release the bus, read the bus, if 0, read in 0, if 1, then read into 1.Ds18b20 TimingInitialization sequence--reset and presence pulsesAll communication from the DS18B20 is initiated by an initialization sequence consisting of a reset pulse. The initialization sequence

you test the output waveform of our products separately? "?? This Zhang San, he was thinking "God, help me, how do I draw these waveforms?"?? Then God appeared: "Zhang San, you just have to do a test, you can use the mathematical method to draw all the input waveform corresponding output waveform."?? God went on: "Give the product a pulse signal, the energy is 1 joules, the output waveform drawing out!" "?? Zhang San obeyed, "then?"?? god added, "for

clock).An important use of counter channels is the generation of precisely timed pulses.There is variations of this use– "one-pulse" pulses,In which a single pulse are generated, and pulse width modulation, in which a series of pulses are generated with the Counte R Uev period.The pulse width is controlled by the Capt

Universal timers are used as input captures. We will use the TIM5 Channel 1 (PA0) to do the input capture, capture PA0 high-level pulse width (with the WK_UP key input), through the serial port printing high-level pulse width timeIntroduction to input CaptureThe input capture mode can be used to measure the pulse width or measurement frequency.

Coding/decoding and recognition driver for infrared remote control Because the encoding formats of different remote control may be different, here is only the single-chip computer recognition program of this remote control I currently use and the method that can decode the infrared remote control with unknown encoding formats. The infrared remote control code is generally composed of the guiding code, system code, system code, function code, function code, fixed stop code, or verification code.

CPU clock speed, that is, the clock frequency (cpuClock speed ). In general, the CPU is as high as, And the is the "CPU clock speed ". Many people think that the CPU clock speed is its running speed. The clock speed of the CPU indicates the speed at which the digital pulse signals oscillate within the CPU, which is not directly related to the actual computing capability of the CPU. Because the frequency does not directly represent the computing speed,

The commonly used bus types of the Microcomputer motherboard include PC/XT, PC/AT, Vesa, and PCI. the CITIC numbers in the I/O slots of different bus vary, familiar with the important signals in the I/o slot is the prerequisite for finding serious faults such as syst

, set the address code and data code serial output from the 17 feet. PT2262/2272 must be paired with the same address code. When a communication machine needs to be added, the user has to turn to the technical staff or the manufacturer to set the same address code, which is relatively difficult for the customer to set, especially for those who do not understand electronics. As people have higher and higher requirements for operations, the use of PT2262/2272 pairs seriously restricts the conven

How can I draw these waveforms?

In earlier computers, the speed of synchronization between memory and the motherboard was equal to FSB, in this way, it can be understood that the CPU FSB directly with the memory, to achieve the synchronous running state between the two. For the current computer system, the two can be completely different, but the meaning of FSB still exist, the computer system most of the frequency is based on the FSB, multiplied by a certain number of multiples to achieve, this multiple can be greater than 1,

I. The concept of PWM and duty-free ratio ①PWM: Also known as pulse width modulation technology, is an analog control mode, the PWM waveform as shown below. ② duty cycle: refers to the proportion of the high level in a period. For example, a duty cycle of 50% means that the high level accounts for half of the period. Two, PWM fixed frequency speed regulation principle In the PWM speed regulation system, it is generally possible to change the dut

After reasonable management, two kinds of distortion factors (dispersion and self phase modulation) in optical fiber can cancel each other, so that the optical soliton can play its role. The color closing causes the pulse signal containing a group of wavelengths to diverge gradually with the increase of the transmission distance. Self-phase modulation (SPM) spreads the spectrum of light pulses horizontally. These two distortion factors have a certain

: Capacitance and inductance values selected at 350kHz, 700kHz and 1600kHz frequencies Note that the higher the frequency, the smaller the number of laps required for the inductor, so the lower the DC impedance. the compensating parts for these error amplifiers are designed for the three switching frequencies in this article, but there is no discussion of how to calculate and select these component values. minimum on-time The minimum on-time controlled by a digital DC power converter is determin
