Driving apparatus, driving method thereof, and scanning mirror

摘要

The disclosure provides a driving apparatus, a driving method thereof, and a scanning mirror. The scanning mirror includes an accumulator unit and a processor unit. The accumulator unit receives and adds up a frequency control word and a first accumulation value to generate a second accumulation value. The processor unit coupled to the accumulator unit receives the second accumulation value. The processor unit generates a driving signal according the second accumulation value and the preset value and adjusts the second accumulation value for outputting the first accumulation value.

主权项

1. A driving apparatus for a scanning mirror, comprising:
an accumulator unit, configured to receive and add up a frequency control word and a first accumulation value to generate a second accumulation value; and a processor unit, coupled with the accumulator unit and configured to, according to the second accumulation value and a preset value, generate a driving signal and adjust the second accumulation value to output the first accumulation value; wherein the processor unit determines whether the second accumulation value is larger than the preset value; when the second accumulation value is larger than the preset value, the processor unit outputs the driving signal at a high logic level, and outputs a difference between the second accumulation value and the preset value to be the first accumulation value; and when the second accumulation value is not larger than the preset value, the processor unit outputs the driving signal at a low logic level, maintains the second accumulation value, and outputs the second accumulation value as the first accumulation value.
