Function Documentation

adc_ConversionIsFinished()

bool adc_ConversionIsFinished

(

void

)

Gets the ADC conversion status of the selected channel.

Return values

1	if the conversion is finished, 0 otherwise.

adc_DmaInit()

void adc_DmaInit

(

void

)

Setup the DMA that copies the current ADC samples to the RAM.

adc_GetConversionResult()

float32_t adc_GetConversionResult

(

void

)

Gets the voltage measured by the selected ADC channel.

Returns

the measured voltage [V].

Note

make sure that the conversion is finished before calling.

adc_StartConversion()

void adc_StartConversion

(

AdcChannel

channel

)

Start the ADC conversion of the selected channel.

Parameters

channel

the ADC channel to acquire.
