@brief Pulse Counter configuration for a single channel

Fields

pulse_gpio_num: c_int

< Pulse input GPIO number, if you want to use GPIO16, enter pulse_gpio_num = 16, a negative value will be ignored

ctrl_gpio_num: c_int

< Control signal input GPIO number, a negative value will be ignored

lctrl_mode: pcnt_ctrl_mode_t

< PCNT low control mode

hctrl_mode: pcnt_ctrl_mode_t

< PCNT high control mode

pos_mode: pcnt_count_mode_t

< PCNT positive edge count mode

neg_mode: pcnt_count_mode_t

< PCNT negative edge count mode

counter_h_lim: i16

< Maximum counter value

counter_l_lim: i16

< Minimum counter value

unit: pcnt_unit_t

< PCNT unit number

channel: pcnt_channel_t

< the PCNT channel
