LL_ADC_INJ_StartConversion()

__STATIC_INLINE void LL_ADC_INJ_StartConversion

(

ADC_TypeDef *

ADCx

)

Start ADC group injected conversion.

Note

On this STM32 serie, this function is relevant for both internal trigger (SW start) and external trigger:

• If ADC trigger has been set to software start, ADC conversion starts immediately.
• If ADC trigger has been set to external trigger, ADC conversion will start at next trigger event (on the selected trigger edge) following the ADC start conversion command.

On this STM32 serie, setting of this feature is conditioned to ADC state: ADC must be enabled without conversion on going on group injected, without conversion stop command on going on group injected, without ADC disable command on going. CR JADSTART LL_ADC_INJ_StartConversion

Parameters

ADCx	ADC instance

Return values

None

Definition at line 6241 of file stm32l4xx_ll_adc.h.

{
  /* Note: Write register with some additional bits forced to state reset     */
  /*       instead of modifying only the selected bit for this function,      */
  /*       to not interfere with bits with HW property "rs".                  */
  MODIFY_REG(ADCx->CR,
             ADC_CR_BITS_PROPERTY_RS,
             ADC_CR_JADSTART);
}

LL_ADC_INJ_StopConversion()

__STATIC_INLINE void LL_ADC_INJ_StopConversion

(

ADC_TypeDef *

ADCx

)

Stop ADC group injected conversion.

Note

On this STM32 serie, setting of this feature is conditioned to ADC state: ADC must be enabled with conversion on going on group injected, without ADC disable command on going. CR JADSTP LL_ADC_INJ_StopConversion

Parameters

ADCx	ADC instance

Return values

None
