Channels, which can be used with this ADC.

You can specify the channel by using a pin-name, like PIN_C0, an internal sensor, like TEMPERATURE_SENSOR or just the plain channel number, like CHANNEL_0.

   @li Supported temperature range: -40 to 125 C
   @li Precision: +-1.5 C

   @see Reference manual (i.e. RM0090) for the formula for the
    calculation of the actual temperature.
   @note The TSVREFE bit must be set to enable the conversion of
    this internal channel.

    this internal channel.

Possible interrupts.

An interrupt can be produced on the end of conversion for regular and injected groups, when the analog watchdog status bit is set and when the overrun status bit is set.

Enum mapping all events on a external trigger converter. The source mapped to each event varies on controller family, refer to the ADC external trigger section on reference manual of your controller for more information

Sampling time of the input voltage.

Total conversion time is T_con = Sampling time + 12 cycles

Acknowledge an interrupt flag.

We use acknowledge here, since it describes the intention rather than the actual implementation.

Clears the specified interrupt flag.

Parameters

flag	The interrupt flag, which shall be cleared.

Precondition

The ADC clock must be started and the ADC switched on with initialize().

Since baudrates are usually generated by prescaling a system clock, only several distinct values can be generated. This method checks if the user requested baudrate is within error tolerance of the system achievable baudrate.

Disable Dma mode for the ADC

disable dma selection for the ADC. If this is disabled no new DMA requests are issued after last transfer

Disables the ADC Conversion Complete Interrupt.

Disables scan mode

Enable Dma mode for the ADC

enable DMA selection for the ADC. If this is enabled DMA requests are issued as long as data are converted and the adc has dma enabled

Enables the ADC Conversion Complete Interrupt.

You could catch the interrupt using this example function:

• for STM32F4XX: MODM_ISR(ADC)
• for STM32F10X: MODM_ISR(ADC1_2)

Precondition

The ADC clock must be started and the ADC switched on with initialize(). Also the Interrupt Vector needs to be enabled first.

Parameters

priority	Priority to set
interrupt	The interrupt, which shall be enabled. See Interrupt for available interrupts.

Note

ADC1 and ADC2 interrupts are mapped onto the same interrupt vector. ADC3 interrupts are mapped onto a separate interrupt vector.

Enables scan mode

get if adc is enabled

Returns

true if ADC_CR2_ADON bit is set, false otherwise

Returns if the th interrupt flags set.

Precondition

The ADC clock must be started and the ADC switched on with initialize()

Initialize and enable the A/D converter.

Enables the ADC clock and switches on the ADC. The ADC clock prescaler will be set as well.

The ADC clock must not exceed 36 MHz for Vdd > 2.4V, or 18MHz for Vdd < 2.4V.

Analog channel selection.

Returns

true if the channel exists and was available, false otherwise

Analog channel selection.

Returns

true if the channel exists and was available, false otherwise

Analog channel selection.

This not for scan mode. The number of channels will be set to 1, the channel selected and the corresponding pin will be set to analog input. If the the channel is modified during a conversion, the current conversion is reset and a new start pulse is sent to the ADC to convert the new chosen channnel / group of channels.

Parameters

channel	The channel which shall be read.
sampleTime	The sample time to sample the input voltage.

Precondition

The ADC clock must be started and the ADC switched on with initialize()

Start a new conversion or continuous conversions.

Precondition

A ADC channel must be selected with setChannel(). When using a STM32F10x a delay of at least t_STAB after initialize() must be waited!

Postcondition

The result can be fetched with getValue()

Attention

When using a STM32F10x, the application should allow a delay of t_STAB between power up and start of conversion. Refer to Reference Manual (RM0008) ADC_CR2_ADON.
