If you still don't have it installed then install The latest STM32CubeF7 library in

http://www.st.com/en/development-tools/stm32cubemx.html

using Help -> Install New Libraries (BTW, ST, why is it under the Help menu?). Find out your repository folder by opening Help -> Updater Settings in the menu, then navigate into that folder, then into STM32Cube_FW_F7_V1.7.0/Projects/STM32F767ZI-Nucleo/Examples_LL to find many examples (ADC too) using the LL drivers.

Hello

youssef.elmzaiti

‌,

we have many STM32 devices. In which one you are interested?

Best regards,

Hello

Majerle.Tilen

we want to migrate from stm32f4 to stm32f7 , the problem is in stm32f4 we use SPL lib and in the stm32f7 there'snt a SPL lib , for this we use SPL2LL to migrate from stm32f4_SPL to STM32F7_LL ,

To migrate from SPL to LL there's some execption like ADC ,NVIC Configuration , this configuration is not compatible betwen SPL and LL .

Best regards,

Youssef

example of equivalence

-

for NVIC configuration :

In SPL

static NVIC_InitTypeDef NVIC_InitStructure_TIM9;

NVIC_InitStructure_TIM9.NVIC_IRQChannel = TIM1_BRK_TIM9_IRQn;

NVIC_InitStructure_TIM9.NVIC_IRQChannelPreemptionPriority = 1;

NVIC_InitStructure_TIM9.NVIC_IRQChannelSubPriority = 0;

NVIC_InitStructure_TIM9.NVIC_IRQChannelCmd = ENABLE;

NVIC_Init(&NVIC_InitStructure_TIM9);

in LL , i put this equvalent !

NVIC_SetPriority((TIM1_BRK_TIM9_IRQn,NVIC_EncodePriority(NVIC_GetPriorityGrouping(),1,0));

NVIC_EnableIRQ(TIM1_BRK_TIM9_IRQn );

but in ADC i don't how i can put the equivalent , for exemple

in SPL we have :

LEGACY_ADC_InitTypeDef Loc_ADC_InitStructure_init_periph_moteur;

/* ADC1 Configuration (ADC1CLK = 15 MHZ) -----------------------------------*/

Loc_ADC_InitStructure_init_periph_moteur.ADC_Resolution = ADC_Resolution_12b ;

Loc_ADC_InitStructure_init_periph_moteur.ADC_ScanConvMode = ENABLE;

Loc_ADC_InitStructure_init_periph_moteur.ADC_ContinuousConvMode = DISABLE;

Loc_ADC_InitStructure_init_periph_moteur.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_Rising ;

Loc_ADC_InitStructure_init_periph_moteur.ADC_ExternalTrigConv = ADC_ExternalTrigConv_T2_CC2;

Loc_ADC_InitStructure_init_periph_moteur.ADC_DataAlign = ADC_DataAlign_Right;

Loc_ADC_InitStructure_init_periph_moteur.ADC_NbrOfConversion = NBR_DE_REGULAR_CHANNEL_ADC1;

ADC_Init( ADC1, &Loc_ADC_InitStructure_init_periph_moteur );

so in LL what's the equivalent

Hi

youssef.elmzaiti

‌,

You didn't precised the STM32 product you are using.

For STM32L4, you find some examples ADC based on LL driver, you can get them as a strt point.

Look underSTM32Cube_FW_L4_V1.8.0\Projects\STM32L476RG-Nucleo\Examples_LL\ADC.
