◆ si1133_channel_params_t

typedef struct _si1133_channel_params si1133_channel_params_t

Si1133 channel parameters.

These parameters define how a "channel" is sampled, ADC settings, resolution timing, etc. These four register values define a single channel. This is a convenience struct to handle them together in the same order as they appear in the parameter list below.
