SAADC channel configuration burst mode

[Edwin]

The macro NRF_DRV_SAADC_DEFAULT_CHANNEL_CONFIG_DIFFERENTIAL does not set the .burst field in the nrf_saadc_channel_config_t structure.

The macro NRF_DRV_SAADC_DEFAULT_CHANNEL_CONFIG_SE does set the .burst field in the nrf_saadc_channel_config_t structure.

As far as I can tell it should be set in both macros. Is this an oversight in the NRF_DRV_SAADC_DEFAULT_CHANNEL_CONFIG_DIFFERENTIAL macro? Or is .burst mode ignored in differential mode?

SDK version 12.2.0.

Hi,

I'm not sure why burst is not in this macro. I will report this internally. It should be possible to use burst mode with differential channels.

You can enable it like this:

nrf_saadc_channel_config_t channel_config =
        NRF_DRV_SAADC_DEFAULT_CHANNEL_CONFIG_DIFFERENTIAL(NRF_SAADC_INPUT_AIN0, NRF_SAADC_INPUT_AIN1);

channel_config.burst = NRF_SAADC_BURST_ENABLED;

Best regards,

Jørgen
