The input voltage range of knob and key shown in 1 Fig. 2 of table
Fig. 3 show the working-flow figure of embodiment according to the present invention.Resistance with key be it is concatenated, key it
Between be it is in parallel, specifically include:
When a chip is powering up, whether software enables the value that ADC reads current ADC input, judge ADC input value in rotation
The voltage range of button.If then carrying out corresponding knob behavior processing according to the input value of ADC and setting current ADC sampled value
For last sampled value, and corresponding threshold value is set, the setting of threshold value and the sampling precision of ADC and the degree of regulation phase of knob
It closes.It is not to judge that key is long-pressing or short-press and carries out corresponding behavior processing.User completes key behaviour under normal circumstances
Make, the input value of ADC can all be in the voltage range of knob, enable ADC interruption after setting up last sampled value and threshold value.
The input voltage range of ADC is in the input range of knob voltage always in the case where not by key pressing.When
Knob rotates, and the absolute value of the difference between the sampled value of ADC and last sampled value is more than threshold value, and interrupt status is set
It rises, the fiducial value of comparator is updated to the sampled value of current ADC by hardware automatically.Software is according to sampled value and last sampled value
Between difference be that can determine whether direction of rotation and the angle of knob.With should have by key pressing and release when, the sampled value of ADC with
The absolute value of difference between last sampled value also can be more than threshold value, and interrupt status has been set, and hardware automatically compares comparator
Value is updated to the sampled value of current ADC.Interruption can be all generated by key pressing and release.Software can be sentenced according to the interval interrupted twice
Disconnected is long-pressing or short-press.
