/* 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
