Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0025] We know that since the actual sampled voltage waveform is non-linear at the microscopic level, that is to say, the sampled value is suddenly large and small, so the current value will be unstable. When the operating clock frequency of the single chip microcomputer is low, if you compare each sampling value and adjust the duty cycle of the PWM, the current value will fluctuate up and down from the set value, which is reflected in the LED circuit, which is the brightness of the brightness. Tiny flickering, jittering. In order to solve this problem, the LED light source debounce control method...
