current level, the active current level, and the transient current peaks that are produced by voltage transitions on input pins. The magnitude of these transient current peaks is dependent on the output capacitance loading of the device. The associated VCC transient voltage peaks can be suppressed by properly selected decoupling capacitors. It is recommended that at least a 0.1 µF ceramic capacitor be used on every device between VCC and GND. This should be a high frequency capacitor of low inherent inductance. In addition, at least a 4.7 µF bulk electrolytic capacitor should be used between VCC and GND for each eight devices. The bulk capacitor

come on !!!        分析下这个下东东  小车跷跷板    怪烦人的

楼主！！小车方面的资料有没！和pwm控制电机的？？？！最主要是关于角度传感器的   ？ 游人说会用到机器人那方面！！可能不！！！？？希望楼主把资料借一份 xiaochangfu940@126.com
