Field Documentation

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 356 of file periph_cpu.h.

uint8_t adc_conf_t::chan

ADC channel.

CPU ADC channel connected to the pin.

which ADC to use (0…7)

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 350 of file periph_cpu.h.

gpio_t adc_conf_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
