Module-prefix ADC

This adc module provides support for analog/digital conversion. It must be initialized during startup.

Function Documentation

ADC_Convert()

void ADC_Convert

(

ADC_HandleTypeDef *

AdcHandle

)

starts the ADC conversion.

Parameters

AdcHandle

pointer to ADC hardware handle

ADC_Ctrl()

void ADC_Ctrl

(

void

)

determines which kind of measurements are made by the ADCs and stores result in database.

It alternates between measurement of the voltage of the backup battery and the voltage of the internal temperature sensor. It starts the conversion with ADC_Convert(). If the conversion is completed, the result is stored in the database.

Here is the call graph for this function:

ADC_GetMCUTemp_C()

float ADC_GetMCUTemp_C

(

void

)

get MCU temperature

ADC_GetValue()

uint16_t ADC_GetValue

(

uint32_t

value

)

get voltage in mV

ADC_GetVBAT_mV()

float ADC_GetVBAT_mV

(

void

)

get coin cell battery voltage

ADC_Init()

void ADC_Init

(

ADC_HandleTypeDef *

AdcHandle

)

initializes the different ADC devices by enabling their corresponding clocks. It is called during startup.

Parameters

AdcHandle

pointer to ADC hardware handle

HAL_ADC_ConvCpltCallback()

void HAL_ADC_ConvCpltCallback

(

ADC_HandleTypeDef *

AdcHandle

)

callback function to the ADC conversion.

It is called automatically when an ADC conversion is complete. Before getting the converted value, it stops the ADC with HAL_ADC_Stop_IT(). Then it gets the converted raw value with HAL_ADC_GetValue(). The raw value is then scaled.

Parameters

AdcHandle

pointer to ADC hardware handle
