OLED adjustment user-specific key

Abstract

The invention discloses an OLED adjustment user-specific key. The OLED adjustment user-specific key comprises an MCU single chip microcomputer, an OLED display key, a key detection circuit, an SPI transmission unit and a power supply, wherein an OLED display screen is arranged on the OLED display key, and characters or pictures are displayed on the OLED display screen; the key detection circuit isused for detecting whether the OLED display key is pressed down or not; the control computer sends a corresponding instruction to the MCU single chip microcomputer according to the detected key value; after the MCU single chip microcomputer receives an instruction sent by the control computer, the color of characters or pictures on the OLED display screen is controlled to be displayed in a corresponding color through the SPI transmission unit; the power supply is used for supplying power to the MCU single chip microcomputer and the external expansion storage module and supplying power to theOLED display key through the MCU single chip microcomputer. The key has the characteristics of simplicity and convenience in operation, easiness in operation, low failure rate and high reaction speed.

Description

technical field [0001] The invention belongs to the technical field of user-specific keys, and in particular relates to an OLED adjustment user-specific key. Background technique [0002] The user-specific key is used as an input and control device for the display console, and is a bridge to realize human-computer interaction. Through the user-specific keys, the user sends a manipulation command, the computer analyzes the manipulation command, and the actuator executes the corresponding command. [0003] In the past, the user-specific keys used in ship display consoles are all like this: the keys are illuminated keys, and the keys are covered with protective shells; the characters required by the user are engraved on the key body or the characters are engraved on the bottom of the key, and pictures cannot be displayed, and the characters are usually single One-color or two-color display; characters remind the user to manipulate the command sent by the button, the dimming of...

Problems solved by technology

[0003]In the past, the user-specific keys used in ship display consoles are all like this: the key is a key with light, and the key is covered with a protective shell; the characters required by the user are engraved on the key body Or the characters are engraved on the lower side of the button, and the picture cannot be displayed. The characters are usually displayed in one or two colors; the characters remind the user to manipulate the command sent by the button, and the dimming of the button lamp is limited to on-site dimming, and cannot be remotely adjusted through the computer in the dispatching room. Light, character engraving is often one-time, the character content and size are engraved once, and cannot be changed in real time according to user needs, and the aesthetics and brightness of characters cannot meet user needs
