ELECTRONIC DEVICE AND INDICATION CIRCUIT THEREFOR

摘要

An indication circuit indicates a first power supply unit and a second power supply unit working in either a 1+1 or a 2+0. The indication circuit includes a first MCU, a second MCU, a first light-emitting diode, and a second light-emitting diode. When the first MCU and the second MCU determine that the power supply units are working in the first operation mode, the first light-emitting diode and second light-emitting diode are made to flicker synchronously. When it is determined that the power supply units are working in the second operation mode, the diodes are made to flicker asynchronously.

1. An indication circuit configured to indicate a first power supply unit and a second power supply unit working in a first operation mode or a second operation mode, the indication circuit comprising:
a first MCU; a second MCU electrically coupled to the first MCU; a first light-emitting diode electrically coupled to the first MCU; and a second light-emitting diode electrically coupled to the second MCU; wherein the first MCU and the second MCU are configured such that in event that the first MCU and the second MCU determine that the first power supply unit and the second power supply unit are working in the first operation mode, the first MCU outputs a pulse signal to the first light-emitting diode and the second MCU, the second MCU outputs the pulse signal to the second light-emitting diode, and the first light-emitting diode and the second light-emitting diode flicker synchronously; wherein the first MCU and the second MCU are further configured such that in event that the first MCU and the second MCU determine that the first power supply unit and the second power supply unit are working in the second operation mode, the first MCU outputs the pulse signal to the first light-emitting diode and the second MCU, the second MCU inverts the pulse signal and outputs the inverted pulse signal to the second light-emitting diode, and the first light-emitting diode and the second light-emitting diode flicker asynchronously.
