RAM掉电保护电路--Design of RAM power-off protection circuit.

该数控直流电流源以精密压控电流源为核心、用单片机、DAC组成控制电路，引入“S类”反馈控制功率放大电路，实现超精密电流控制、具备精准的扩流能力、低失调、有步进、同时带有 丰富扩展功能的精密电流源。经过ADC采样，完成输出电流显示功能，并使输出范围覆盖0～2A，是理想的电流源解决方案。-The CNC precision DC voltage-controlled current source to current source at the core, with single-chip, DAC control circuit components, the introduction of " S-type" feedback control circuit power amplifier to achieve ultra-precision current control, with precise flow capacity expansion, low disorder, there is stepping at the same time and expanded with rich precision current source. ADC sampling after completion of output current display, and output cover 0 ~ 2A, the current source is an ideal solution.

由于普通单片机只有一个串口,由于用户可能会用到多个串口,而对于双串口的单片机价格贵,不如自己动手选择两个IO口,自己模拟串口通讯,以下为模拟串口程序.-Because there is only one common single-chip serial port, as the user might use multiple serial ports, dual serial ports for the price of your microcontroller, it is better to select two IO own mouth that they simulation serial communication, the following for Simulation of serial procedures.

L298N是ST公司生产的一种高电压、大电流电机驱动芯片。该芯片采用15脚封装。主要特点是：工作电压高，最高工作电压可达46V；输出电流大，瞬间峰值电流可达3A，持续工作电流为2A；额定功率25W。内含两个H桥的高电压大电流全桥式驱动器，可以用来驱动直流电动机和步进电动机、继电器线圈等感性负载；采用标准逻辑电平信号控制；具有两个使能控制端，在不受输入信号影响的情况下允许或禁止器件工作有一个逻辑电源输入端，使内部逻辑电路部分在低电压下工作；可以外接检测电阻，将变化量反馈给控制电路。使用L298N芯片驱动电机，该芯片可以驱动一台两相步进电机或四相步进电机，也可以驱动两台直流电机。-L298N is produced by ST a high-voltage, high current motor driver chip. The chip uses 15-pin package. Main features are: high voltage, the maximum working voltage up to 46V output current, instantaneous peak current up to 3A, continuous operating current of 2A rated power of 25W. Contains two H-bridge high-voltage high-current full-bridge driver can be used to drive DC motors and stepper motors, relay coils and other inductive load using standard logic level signal control has two enable control terminal, input signal without affecting the case to permit or prohibit the device work a logic supply input, so that part of the internal logic circuits at low voltage work can be an external sense res
