Abstract

The invention discloses a dimming standard keyboard which comprises a main control circuit, a USB interface circuit, a key input circuit and a backlight circuit. The main control circuit adopts a single chip microcomputer GD32, the single chip microcomputer GD32 is provided with an HID communication module and a keyboard communication module, the HID communication module has a dimming function, the keyboard communication module has a keyboard function, and the HID communication module and the keyboard communication module communicate with an external host through the USB interface circuit; the key input circuit is connected with keys on the dimming standard keyboard; a backlight lamp is arranged on the backlight circuit; the host sends a dimming instruction to the HID communication module of the main control circuit through the USB interface circuit; and after the HID communication module of the main control circuit receives the dimming instruction, the charging current of the backlight circuit is adjusted, so that the brightness of the backlight lamp is adjusted, and the dimming of the dimming standard keyboard is realized. A user can adjust the backlight of the keyboard according to the light intensity and the color temperature of the surrounding environment and personal use habits so as to relieve visual fatigue generated in the use process of the user.

Description
