Default configuration parameters structure for ADS1X1X ADC devices.

This macro defines the default parameter structure used to initialize ADS1X1X analog-to-digital converter devices. The structure contains all necessary configuration options including resolution, data rate, gain, and operational modes.

Warning

The following parameters are mandatory and must be explicitly configured:

• ads1x1x_params_t::bits_res - ADC resolution, must be set to either:
  • ADS101X_BITS_RES for 12-bit resolution (ADS101x series)
  • ADS111X_BITS_RES for 16-bit resolution (ADS111x series)
• ads1x1x_params_t::dr - Data rate configuration, must be set to a valid sampling rate value appropriate for the selected device variant

Note

Other parameters in the structure have sensible defaults but can be customized based on application requirements such as input multiplexer configuration, programmable gain amplifier settings, and comparator modes.
