Field Documentation

◆ avg

uint8_t adc_conf_t::avg

Hardware averaging configuration.

Written as-is to ADCx_SC3 before conversion, use ADC_AVG_NONE and ADC_AVG_MAX as a shorthand notation in the board configuration

Definition at line 360 of file periph_cpu.h.

◆ chan

uint8_t adc_conf_t::chan

CPU ADC channel connected to the pin.

which ADC to use (0…7)

ADC channel.

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

Definition at line 286 of file periph_cpu.h.

◆ cmu

CMU_Clock_TypeDef adc_conf_t::cmu

the device CMU channel

Definition at line 376 of file periph_cpu.h.

◆ dev [1/3]

uint8_t adc_conf_t::dev

ADC device used.

ADCx - 1 device used for the channel.

Definition at line 375 of file periph_cpu.h.

◆ dev [2/3]

uint8_t adc_conf_t::dev

ADCx - 1 device used for the channel.

Definition at line 285 of file periph_cpu.h.

◆ dev [3/3]

ADC_Type* adc_conf_t::dev

ADC module.

Definition at line 341 of file periph_cpu.h.

◆ pin

gpio_t adc_conf_t::pin

pin connected to the channel

Pin connected to the channel.

pin to use

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

Definition at line 284 of file periph_cpu.h.

◆ pinsel

uint8_t adc_conf_t::pinsel

PINSEL# of the ADC pin.

Definition at line 198 of file periph_cpu.h.

◆ pinsel_msk

uint32_t adc_conf_t::pinsel_msk

PINSEL Mask for ADC pin.

Definition at line 199 of file periph_cpu.h.
