CC26X2 specific extension to ADCBuf_Params.
To use non-default CC26X2 specific parameters when calling ADCBuf_open(), a pointer to an instance of this struct must be specified in ADCBuf_Params::custom. Alternatively, these values can be set using the control function after calling ADCBuf_open().
| ADCBufCC26X2_Sampling_Duration ADCBufCC26X2_ParamsExtension::samplingDuration |
Amount of time the ADC spends sampling the analogue input
| ADCBufCC26X2_Sampling_Mode ADCBufCC26X2_ParamsExtension::samplingMode |
Specifies whether the ADC spends a fixed amount of time sampling or the entire time since the last conversion
| ADCBufCC26X2_Reference_Source ADCBufCC26X2_ParamsExtension::refSource |
Specifies whether the internal reference of the ADC is sourced from the battery voltage or a fixed internal source
| bool ADCBufCC26X2_ParamsExtension::inputScalingEnabled |
Disable input scaling. Input scaling scales an external analogue signal between 0 and 4.3V to an internal signal of 0 to ~1.4785V. Since the largest permissible input to any pin is VDDS, the maximum range of the ADC is effectively less than 3.8V and continues to shrink as the battery voltage drops. With input scaling disabled, the external analogue signal is passed on directly to the internal electronics. Signals larger than ~1.4785V will damage the device with input scaling disabled.
| Input scaling status | Maximum permissible ADC input voltage |
|---|---|
| Enabled | VDDS (Battery voltage level) |
| Disabled | 1.4785V |
