Technical Examples

A status indicator and status indicating method are provided to indicate multi-working statuses of an electronic device with a single status indicator. The status indicator includes an MCU (10, 10'), and an LED circuit. The MCU includes a CPU (101), a ROM (103), a RAM (105), a counter (107, 107') and an output port (111, 111'). In a first embodiment, the MCU further includes a PWM register (109). The CPU detects a current working status, and controls the PWM output port to output corresponding PWM waves via the PWM register according to the first embodiment, and executes an interrupt service routine stored in the ROM, thereby outputs corresponding PWM waves via the output port according to a second embodiment. The PWM waves are delivered to the LED circuit to make the LED indicate the current working status.
