Electronic device capable of adjusting light emitting frequency, computer system having the same and method for adjusting light emitting frequency of electronic device

An electronic device capable of adjusting light emitting frequency, comprising:

• an oscillator, used to generate an oscillation signal;
• a microcontroller, connected to the oscillator, wherein the microcontroller is used to define that a quantity of oscillation times of the oscillator within a unit time period is an original quantity of oscillation times, and set a correspondence between a switching period and the original quantity of oscillation times, and the microcontroller is further used to receive the oscillation signal to calculate a time elapse;
• and
• a light emitting module, connected to the microcontroller, wherein the microcontroller is configured to control on or off of the light emitting module according to the switching period and the time elapse, wherein
• the microcontroller further comprises:
• a counting module, used to count, after receiving a correction trigger signal, a total quantity of oscillation times of the oscillator according to the oscillation signal;
• and
• an adjustment module, used to obtain a corrected quantity of oscillation times within the unit time period according to the total quantity of oscillation times counted within a sampling time period, and reset a correspondence between the switching period and the corrected quantity of oscillation times.
