touch_pad_set_cnt_mode() function

Set touch sensor charge/discharge speed for each pad. If the slope is 0, the counter would always be zero. If the slope is 1, the charging and discharging would be slow, accordingly. If the slope is set 7, which is the maximum value, the charging and discharging would be fast.

Arguments

Argument

Description

touch_num

touch pad index

slope

touch pad charge/discharge speed

opt

the initial voltage

Return value

- ESP_OK on success - ESP_ERR_INVALID_ARG if argument is wrong

Notes

The higher the charge and discharge current, the greater the immunity of the touch channel, but it will increase the system power consumption.
