Description: ZylTimer is a high resolution, long-term Delphi / C++Builder timer component which provides a higher precision than the standard Delphi / C++ Builder TTimer component.
TTimer component which ships with Delphi / C++Builder uses the Windows Message Queue to generate the OnTimer event. Due to this approach it s impossible to get accurate timer intervals smaller than 50 milliseconds. Platform: |

Description: VB记时器编程的讨论 在很多场合下编程（例如工业控制、游戏）中需要比较精确的记时器，本文讨论的是在VB下实现记时器的若干方法以及它们的精度控制问题。
在VB中最常用的是Timer控件，它的设置和使用都非常方便，理论上它的记时精度可以达到1ms(毫秒)。但是众所周知的，实际上Timer在记时间隔小于50ms之下是精度是十分差的。它只适用于对于精度要求不太高的场合。 -VB timer programming on many occasions to discuss programming (such as industrial control, games) need a more precise timer, this discussion is in the VB timer to achieve a number of methods and their precision control. The most commonly used in the VB Timer control is, it' s very easy to set up and use, in theory, its accuracy can be achieved when the mind 1ms (ms). But we all know, in fact, every time Timer is less than 50ms in the mind is under the precision is very poor. It applies only to not too high for the accuracy of the occasion. Platform: |

Description: 可以精确到1毫秒的定时器——多媒体定时器ocx控件，1、HighResolutionTimer，2、HL_mmTimer2，两者几乎一样，精度高，但都有个问题：一个进程中只能用一个此种控件！一个工程中只能添加一个控件实例！第二个不执行，但不会导致程序崩溃！本控件采用多媒体定时器包装而成，注意打包时带上"winmm.dll"。
为使VB6能用上它，用VC6封装出DLL，提供API接口，通过发送WM_KEYUP消息到VB6的用户控件触发计时事件-Accurate to 1 millisecond timer- multimedia timer ocx controls, 1, HighResolutionTimer, 2, HL_mmTimer2, both almost the same, high precision, but there is a problem: a process can only use one such control! A project can only add one instance of the control! The second does not perform, but will not cause the program to crash! The use of multimedia timer controls the packaging is made to bring attention to "winmm.dll" when packed.
To make it can be used on VB6, VC6 package the DLL, provide API interface, by sending a message to WM_KEYUP VB6 user control to trigger timed events Platform: |

Description: 数字频率计作为一种常见的应用电子仪器设备，传统的一般可以完全由硬件电路搭接而成，如采用基于555 定时器电路的多功能数字频率计的设计便是可取的路径之一，不用依靠单片机。但是这种电路存在一些缺点，且测频精度也不如单片机的高。在科学研究和生产实践中，如工业过程控制，生物医学，地震模拟机械振动等领域常常要用到频率计。利用单片机采用程序设计方法来设计频率计，其测频精度高。且线路相对简单，结构紧凑，价格低廉，系统稳定度高，抗干扰能力强，用途广泛等优点-Digital frequency meter is a common application of electronic devices, the traditional general can completely by hardware circuit lap, such as the use of 555 timer circuit based multifunctional digital frequency meter design is the one of the desirable paths without by MCU. But this circuit has some shortcomings, and the accuracy of frequency measurement as well as the MCU high. In the scientific research and production practice, such as industrial process control, biomedicine, seismic modelingmechanical vibration and other fields often use frequency meter. The use of single-chip microcomputer to design frequency meter program design method is adopted, the frequency measurement precision. And the lines are relatively simple, compact structure, low cost, high stability, strong anti-interference ability, wide range of uses, etc. Platform: |

Description: 基于51单片机的电子钟，可通过EC11旋转编码器修改时间，LCD1602显示时间。
时钟精度可通过T0定时器的初值来调节，但是要实现高精度晶振的关系非常大，本程序只是粗略的进行电子钟的仿真，如果要实现高精度还是要用其他外接模块来配合。(Based on 51 microcontroller electronic clock, can be modified by EC11 rotary encoder time, LCD1602 display time.
The clock accuracy can be adjusted by the initial value of T0 timer, but to achieve the high precision crystal oscillator is very large, this procedure is only rough conduct electronic clock simulation, if you want to achieve high precision or to use other external modules to cooperate.)
