Typedef Documentation

§ ADCBufMSP432_Reference_Source

typedef enum ADCBufMSP432_Reference_Source ADCBufMSP432_Reference_Source

ADCMSP432 reference source These fields are used by ADCBufMSP432_HWAttrs to specify the reference voltage for each channel.

§ ADCBufMSP432_Sampling_Duration

typedef enum ADCBufMSP432_Sampling_Duration ADCBufMSP432_Sampling_Duration

ADCMSP432 sampling duration These fields define the MSP432 ADC sampling duration (sample and hold time) in the pulse width unit. User can specify the differnt sampling duration in the ADCBufMSP432_ParamsExtension when opening the ADC.

§ ADCBufMSP432_Timer_Reference_Source

typedef enum ADCBufMSP432_Timer_Reference_Source ADCBufMSP432_Timer_Reference_Source

§ ADCBufMSP432_ParamsExtension

typedef struct ADCBufMSP432_ParamsExtension ADCBufMSP432_ParamsExtension

MSP432 specfic extension to ADCBuf_Params.

To use non-default MSP432 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().

§ ADCBufMSP432_Channels

typedef struct ADCBufMSP432_Channels ADCBufMSP432_Channels

ADCMSP432 Channel setting These fields define channel-specific settings: GPIO and reference voltage. These settings happen when ADCBuf_convert() is called.

typedef struct ADCBufMSP432_HWAttrs ADCBufMSP432_HWAttrs

ADCBufMSP432 Hardware attributes These fields are populated by PinMux tool but user is allowed to change for different channels setting.

A sample structure is shown below:

ADCBufMSP432_Channels adcBufMSP432Channels[] = {
{
.adcPin = ADCBufMSP432_P5_5_A0,
.refSource = ADCBufMSP432_VREFPOS_INTBUF_VREFNEG_VSS,
.refVoltage = 2500000
}
};
const ADCBufMSP432_HWAttrs adcbufMSP432HWAttrs[] = {
{
.intPriority = ~0,
.channelSetting = adcBufMSP432Channels,
