* adc_cal: c2: Add efuse functions for reading calibration * adc_cal: c3: Add efuse functions for reading calibration * adc_cal: c6: Add efuse functions for reading calibration * adc_cal: Add extra traits to support calibration - `AdcCalScheme<ADCI>` implemented for each calibration scheme (basic, linear, curved) - `AdcCalEfuse` implemented for each ADC unit to get calibration data from efuse bits * adc_cal: Add basic ADC calibration scheme Basic calibration is related to setting some initial bias value to ADC unit. Such values usually is stored in efuse bit fields but also can be measured in runtime by connecting ADC input to ground internally. * adc_cal: Add line fitting ADC calibration scheme This scheme also includes basic calibration and implements gain correction based on reference point. Reference point is a pair of reference voltage and corresponding mean raw ADC value. Such raw values usually is stored in efuse bit fields for each supported attenuation. Possibly it also can be measured in runtime by connecting ADC to reference voltage internally. * adc_cal: Add curve fitting ADC calibration scheme This scheme also includes basic and linear and implements final polynomial error correction. * adc_cal: riscv: Add ADC calibration implementation for riscv chips * adc_cal: c2: Add calibrated ADC reading example This example uses line fitting calibration scheme by default. It periodically prints both raw measured value and computed millivolts. * adc_cal: c3: Add calibrated ADC reading example This example uses curve fitting calibration scheme by default. It periodically prints both raw measured value and computed millivolts. * adc_cal: c6: Add calibrated ADC reading example This example uses curve fitting calibration scheme by default. It periodically prints both raw measured value and computed millivolts. * adc_cal: riscv: Add changelog entry for ADC calibration |

esp-hal-common
no_std HAL implementations for the peripherals which are common among Espressif devices. Implements a number of the traits defined by embedded-hal.
This crate should not be used directly; you should use one of the device-specific HAL crates instead:
