在集成电路中,通常采用T型解码网络实现数字量往模拟的转换,再利用运算放大器完成模拟电流变为模拟电压的转换。所以,要把一个数字量变为模拟电压,实际上需要两个环节,先把数字量变为模拟电流,这是由D/A转换器完成的;再将模拟电流变成模拟电压,这是由运算放大器完成的。有时D/A转换器芯片只包含前一个环节,有些D/A转换器则包含两个环节,用前一种芯片时,需要外接运算放大器才能得到模拟电压。-In integrated circuits, the usual T-decode digital networks to analog conversion, and then complete the simulation of the use of op-amp current into the analog voltage conversion. Therefore, it is necessary to become a digital simulation of voltage, in fact, need two links, first into a digital simulation of currents, this is determined by D/A converters completed then simulate current into the analog voltage, this is determined by computing completed amplifier. Sometimes D/A converter chip contains only a part before, some D/A converter includes two aspects, before a chip, the need for external op-amp voltage can be simulated.

特此感谢Redfox的源程序,游戏中的地图数据和角色移动的核心代码基本保持原版,对这部分内容仅作了格式上的调整。
目前只能算是入门级水平,如果游戏中有任何逻辑错误,请大家自行对源代码修改(源代码是:版权没有,翻版不纠!
但请大家尊重Redfor的源码,如要转载,请与原作者联系)-Redfox hereby like to thank the source, in-game map data and the role of mobile code essential to maintain the core of the original, this part of the contents were only format adjustments. The current level can only be regarded as entry-level, if the game has no logic error, please everyone to modify the source code (source code is: there is no copyright infringement is not correct! But please respect everyone Redfor source, such as the need to reprint, please contact contact the original author)
