Function Documentation
◆ calib_init()
| esp_err_t calib_init | ( | adc_obj_t * | adc_obj | ) |
◆ config_adc1()
| esp_err_t config_adc1 | ( | adc_obj_t * | adc_obj | ) |
◆ enable_adc1()
| esp_err_t enable_adc1 | ( | adc_obj_t ** | adc_obj | ) |
call function config_adc1() and characterize_adc1().
- Returns
- esp_err_t - returns ESP_OK if Configuration and Characterization of adc1 is successful, else it returns ESP_ERR_INVALID_ARG.
◆ read_adc()
| int read_adc | ( | adc_handle_t | adc_handle, |
| int | gpio | ||
| ) |
Reads the adc value from the GPIO(channel) specified.
- Parameters
-
adc_handle_t adc_handle - pointer to adc object. int gpio - gpio pin number of the channel to be read.
- Returns
- int - returns the adc value read from the channel.
