touch_pad_set_meas_time() function
Set touch sensor measurement and sleep time. Excessive total time will slow down the touch response. Too small measurement time will not be sampled enough, resulting in inaccurate measurements.
Syntax
esp_err_t touch_pad_set_meas_time(uint16_t sleep_cycle,
uint16_t meas_cycle)
__attribute__((deprecated("please use 'touch_pad_set_measurement_clock_cycles' and 'touch_pad_set_measurement_interval' instead")));
Implemented in ![]()
touch_sensor.c:160
Return value
- ESP_OK on success
Notes
The touch sensor will count the number of charge/discharge cycles over a fixed period of time (specified as the second parameter). That means the number of cycles (raw value) will decrease as the capacity of the touch pad is increasing. The greater the duty cycle of the measurement time, the more system power is consumed.
