Description

Technical Field

[0001] This utility model belongs to the field of potentiometer technology, specifically relating to a settable intelligent digital potentiometer. Background Technology

[0002] A potentiometer is a resistive element with three leads whose resistance can be adjusted according to a certain rule. A potentiometer typically consists of a resistive element and a movable brush. When the brush moves along the resistive element, a resistance value or voltage is obtained at the output terminal that is related to the displacement. For example, the existing CN102969103A potentiometer, however, requires alignment with a reference position during installation, and its rotation angle is limited to 90 or 120 degrees, unable to achieve 360-degree rotation. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a configurable intelligent digital potentiometer, comprising: Shaft; A magnet is disposed on the rotating shaft; The encoder receives the magnet information; Processing device; A button is used to set the zero point and control the output; the button and the encoder are electrically connected to the input terminal of the processing device. The rotation of the shaft drives the magnet to rotate, thereby causing the output signal of the encoder to change according to the position of the magnet. This information is transmitted to the processing device, and the processing device outputs a signal based on the information.

[0004] It also includes a circuit board and a housing, with a mounting cavity formed between the housing and at least a portion of the circuit board. The encoder and the processing device are electrically connected to the circuit board located within the mounting cavity. The circuit board forms a base, and the circuit board and housing are detachably connected by fasteners. The button is electrically connected to the back of the circuit board, located outside the mounting cavity.

[0005] It also includes an indicator light, which is electrically connected to the back of the circuit board and located outside the mounting cavity. The indicator light is electrically connected to the output terminal of the processing device.

[0006] The circuit board at least partially forms an extension located outside the mounting cavity. The extension has a wiring position electrically connected to a circuit on the circuit board. External wires are electrically connected to the wiring position for connecting power supplies and external signal input / output wires. This wiring position can be electrically connected to a connector for connecting to a computer, allowing for control of the invention via the computer, such as for rewriting code within a microcontroller.

[0007] The outer casing has a rotation channel, and the rotating shaft is at least partially rotatably connected within the rotation channel. The outer casing also has mounting threads. These threads allow the outer casing to be installed in the desired application environment. Rotational friction can exist between the rotating shaft and the rotation channel, enabling rotational limiting, such as damping, through friction during rotation.

[0008] The encoder detects the rotation angle of the magnet, converts the angle information, and sends it to the processing device. The processing device outputs the information according to the button settings. The processing device includes a microcontroller.

[0009] Double-clicking the button sets any position of the magnet to zero. A long press sets the output value to increase or decrease when rotating clockwise. When rotating clockwise, the indicator light illuminates when the output value increases or decreases; or when rotating counterclockwise, the indicator light illuminates when the output value increases or decreases.
