Module esp_idf_svc::hal::adc::attenuation

Constants

• DB_2_5
• DB_6
• DB_11
• NONE
• adc_atten_t_ADC_ATTEN_DB_0
  <No input attenuation, ADC can measure up to approx.
• adc_atten_t_ADC_ATTEN_DB_2_5
  <The input voltage of ADC will be attenuated extending the range of measurement by about 2.5 dB
• adc_atten_t_ADC_ATTEN_DB_6
  <The input voltage of ADC will be attenuated extending the range of measurement by about 6 dB
• adc_atten_t_ADC_ATTEN_DB_11
  <This is deprecated, it behaves the same as ADC_ATTEN_DB_12

Type Aliases

• adc_atten_t
  @brief ADC attenuation parameter. Different parameters determine the range of the ADC.
