Zooming: oversampling and Shrinking : undersampling Zooming requires two steps: Creation of new pixel locations, Assignment of gray levels to those new locations. To shrink an image by one-half, delete every other row and column.
这个是TI公司的高级单片机的仿真器资料，通过本资料的学习，学者可以通过自己动手做出好用的仿真器，给430单片机学习者提供了节省学习成本。(This is TI' s advanced microcontroller emulator information, through this information, learning, and scholars can make yourself easy to use emulator to the microcontroller 430 provides the learners to study the cost savings.)
说明： pic16f877a 与ds1302的驱动程序 格式为asm(pic16f877a with ds1302 driver asm format)
说明： 用C51编写的程序 很实用 很有参考价值 在此分享(Procedures prepared by C51 is a very practical reference value in this share)
该电源以单端反激式DC-DC变换器为核心。市电通过自耦式调压器，隔离变压器，整流滤波后产生直流电压，经DC-DC变换得到题目所需输出电压，实现了开关稳压电源的设计。(The power to single-ended flyback DC-DC converter at the core. City through the auto-type voltage regulator, isolation transformer, rectifier filter DC voltage generated by the DC-DC conversion has been the subject output voltage required to achieve a switching power supply design.)
汉字点阵字库仿真，这个字库挺好用的，希望能为大家提供帮助！(Chinese character dot-matrix font Simulation)
伺服直流电机专用IC高精确度的PID位置控制,闭环控制(DC motor servo IC dedicated high-precision location of the PID control, closed-loop control)
本系统基于反馈控制思想，由交直流转换电路、DC-DC变换器、步进电路模块和显示模块4个模块电路构成开关稳压电源。交直流转换电路整流部分采用全波桥式整流电路形式，DC-DC变换器以TL494有主核心设计并加上简单滤波电路及RC放电回路所构成的回路控制器。它能把脉冲宽度变化的信号转换成与脉冲宽度成正比变化的直流信号，进而实现闭环单回路控制。由单片机控制 数字定位器X9241的电阻,进而控制输出电压。显示模块由LCD1602构成。 (Based on feedback control of the system of thought, from AC-DC converter circuit, DC-DC converters, stepper circuit module and display module 4 module circuit switching power supply. AC-DC converter circuit using full-wave rectifier part of the circuit form of bridge rectifier, DC-DC converter to TL494 have the main core of the design and add a simple RC filter circuit and discharge circuit posed by the loop controller. It can change the pulse width signals into changes with the pulse width is proportional to the DC signal, and thus realize the closed-loop single-loop control. By the single-chip microcomputer to control the number of locator X9241 resistance, thereby control the output voltage. LCD1602 constituted by the display module.)
