    The 6.0 release of Visual C++ shows Microsoft s continued focus on Internet technologies and COM, WHich are key components of the new Windows Distributed interNet Application Architecture (DNA). In addition to supporting these platform initiatives, Visual C++ 6.0 also adds an amazing number of productivity-boosting features such as Edit And Continue, IntelliSense, AutoComplete, and code tips. These features take Visual C++ to a new level. We have tried to make sure that this book keeps you up to speed on the latest technologies being introduced into Visual C++.

  • 数控电源智能仿真资料

    正在做0-30V、0-15A的数控电源,程序搞了很久终于差不多了,得瑟得瑟自己腐蚀的板子:显示器件最初用128*64的是OLED小屏:屏幕太小感觉与机壳不配,换1.8寸的TFT彩屏:主控选用了STM8L152K4,SPI口彩屏。屏显第一行设置电压电流。第二行用大字体显示输出电压、电流。中部为输出电压电流曲线。屏幕成128*160分辨率后,最初想在多出的“空间”显示散热器、变压器温度、配色菜单或者为电池充电预置参数什么的,感觉意义不大,最终放了两条输出曲线。最下面是功率、电阻AH、WH等参数。用了3个定时器,tim1设为编码器模式,驱动编码器。tim2产生PWM信号,启用了一个ADC通道采集热敏电阻信号,根据温度改变PWM占空比,实现散热扇温控调速。tim3精确定时,累计时间用于AH、WH参数计算。DAC为12位的双通道芯片MCP4822。芯片内置的12位ADC采集输出电压、电流和热敏电阻信号,前两者用于显示和计算,后者用于风扇温控。做到后来感觉不该在此处偷懒,用独立的ADC芯片就好了,显示和偏移就都能到1mV、1mA了,现在这板子,没辙了。启用了2个引脚的外部中断,以外部中断方式触发更新设置值和编码器按键值,编码器按键值决定设置位。反白(红)位为当前设置位,旋转编码器可改变设置值,短按编码器开关改变设置位,长按为输出\预制切换。还有3条口线用于控制继电器,切换输入电压。
