struct adc_conf_t

ADC device configuration.

Available number of ADC devices.

ADC channel configuration data.

ADC line configuration values.

CPU specific ADC configuration.

ADC channel configuration data

CMU_Clock_TypeDef cmu

the device CMU channel

ADC_Type * dev

ADC module.

gpio.h::gpio_t pin

pin to use

pin connected to the channel

Use GPIO_UNDEF non-muxed ADC pins, e.g. ADC0_DP, or for internal channels, e.g. Bandgap

uint8_t chan

ADC channel.

CPU ADC channel connected to the pin.

internal channel the pin is connected to

Written as-is to ADCx_SC1x before conversion. This also decides single-ended or differential sampling, see CPU reference manual for ADCx_SC1x

uint8_t avg

Hardware averaging configuration.

Written as-is to ADCx_SC3 before conversion, use kinetis/include/periph_cpu.h::ADC_AVG_NONE and kinetis/include/periph_cpu.h::ADC_AVG_MAX as a shorthand notation in the board configuration

ADC_TypeDef * dev

ADC device used.

ADCx - 1 device used for the channel.
