Embodiment Construction
[0022] The principles and embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0023] Such as figure 1 As shown, the present invention sets up a circuit, the circuit has several detection nodes, and each detection node has a value of an electrical parameter that is different, so that the electrical parameter can be used as a unique identifier corresponding to the address of the module and / or device. In this embodiment, the circuit adopts a voltage divider circuit, and multiple resistors are connected in series with each other, and then a power supply is connected to the first and last ends of the resistor string to form multiple detection nodes with different voltage values. The voltage dividing circuit is not only simple in structure, but also the specific voltage value of the power supply is not limited, and can be selected according to the power supply situation of the module and / or device and the voltage de...
