Zusammenfassung: | The embodiment of the application provides an LED display control method and intelligent equipment; the method is applied to the intelligent equipment; the intelligent equipment comprises a CPU, a MCU, an LED indication lamp, an LED indication lamp driving circuit and a switching circuit; the CPU and the MCU are connected with the driving circuit through the switching circuit; when the CPU cannot control or no longer controls the LED indication lamp display state, the MCU can obtain the LED indication lamp control right and controls the switching circuit to connect the MCU with the LED indication lamp driving circuit, thus further controlling the LED indication lamp to display according to LED interaction needs. The control method uses the MCU and the CPU to alternatively control the LED indication lamp, thus solving the problems that the CPU of existing intelligent equipment can open the LED interaction function only under a normal operation state, enhancing the LED interactive function flexibility, and prov |
