pcnt_channel_set_edge_action() function
Set channel actions when edge signal changes (e.g. falling or rising edge occurred). The edge signal is input from the `edge_gpio_num` configured in `pcnt_chan_config_t`. We use these actions to control when and how to change the counter value.
Syntax
esp_err_t pcnt_channel_set_edge_action(pcnt_channel_handle_t chan,
pcnt_channel_edge_action_t pos_act,
pcnt_channel_edge_action_t neg_act);

Description
Create PCNT channel for specific unit, each PCNT has several channels associated with it
Set channel actions when level signal changes (e.g. signal level goes from high to low). The level signal is input from the `level_gpio_num` configured in `pcnt_chan_config_t`. We use these actions to control when and how to change the counting mode.
