六、模拟输入接口在大多数情况下,模拟输入的变化特性表明它们不能直接连至机器人的控制电路。如果您想对输入信号进行量化,您应使用某种形式的模数转换。此外,您可能需要对模拟输入进行条件优化,使得其数值可以可靠测量。这包括对输入的放大和缓冲。 1.电压比较器电压比较器接受线性的模拟电压,输出一个简单的通/断(低/高)信 Sixth, the analog input interface In most cases, the changing characteristics of the analog input shows that they can not be directly connected to the robot control circuit. If you want to quantify the input signal, you should use some form of analog-to-digital conversion. In addition, you may need to conditionally optimize analog inputs so that their values ​​can be reliably measured. This includes magnification and buffering of the input. 1. Voltage Comparator Voltage The comparator accepts a linear analog voltage and outputs a simple on / off (low / high) signal
