/* LEDC tested by PCNT in some case
|

* PCNT can get the LEDC waveform frequency
|
||||
*
|
||||
* test environment of UT_T1_LEDC:
|
||||
* 1. connect GPIO18 with GPIO4
|
||||
* 2. connect GPIO5 to 3.3v (in case of it is pulled down by default)
|
||||
*
|
||||
* some calculation related with duty:
|

* real duty = duty/2^duty_resolution
