*** Configuration of top level parameters related to ADC ***
|

============================================================
|
|
[..]
|
|
|
|
(#) Enable the ADC interface
|
|
(++) As prerequisite, ADC clock must be configured at RCC top level.
|
|
|
|
(++) For STM32F30x/STM32F33x devices:
|
|
Two possible clock sources: synchronous clock derived from AHB clock
|
|
or asynchronous clock derived from ADC dedicated PLL 72MHz.
|
|
- Synchronous clock is mandatory since used as ADC core clock.
|
|
Synchronous clock can be used optionally as ADC conversion clock, depending on ADC init structure clock setting.
|
|
Synchronous clock is configured using macro __ADCx_CLK_ENABLE().
|
|
- Asynchronous can be used optionally as ADC conversion clock, depending on ADC init structure clock setting.
|
|
Asynchronous clock is configured using function HAL_RCCEx_PeriphCLKConfig().
|
|
(+++) For example, in case of device with a single ADC:
|
|
Into HAL_ADC_MspInit() (recommended code location) or with
|
|
other device clock parameters configuration:
|
|
(+++) __HAL_RCC_ADC1_CLK_ENABLE() (mandatory)
|
|
(+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC (optional, if ADC conversion from asynchronous clock)
|
|
(+++) PeriphClkInit.Adc1ClockSelection = RCC_ADC1PLLCLK_DIV1 (optional, if ADC conversion from asynchronous clock)
|
|
(+++) HAL_RCCEx_PeriphCLKConfig(&RCC_PeriphClkInitStructure) (optional, if ADC conversion from asynchronous clock)
|

(+++) For example, in case of device with 4 ADCs:
|
|
|
|
(+++) if((hadc->Instance == ADC1) || (hadc->Instance == ADC2))

(+++) {
|

|
|
(+++) HAL_RCCEx_PeriphCLKConfig(&RCC_PeriphClkInitStructure); (optional, if ADC conversion from asynchronous clock)
|
|
(+++) }
|
|
|
|
(++) For STM32F37x devices:
|
|
One clock setting is mandatory:
|
|
ADC clock (core and conversion clock) from APB2 clock.
|
|
(+++) Example:
|
|
Into HAL_ADC_MspInit() (recommended code location) or with
|
|
other device clock parameters configuration:
|
|
(+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC
|

(+++) PeriphClkInit.AdcClockSelection = RCC_ADCPLLCLK_DIV2
|
|
(+++) HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit)

(#) ADC pins configuration
|
|
(++) Enable the clock for the ADC GPIOs
|
|
using macro __HAL_RCC_GPIOx_CLK_ENABLE()
|
|
(++) Configure these ADC pins in analog mode
|
|
using function HAL_GPIO_Init()
|
|
|
|
(#) Optionally, in case of usage of ADC with interruptions:
|
|
(++) Configure the NVIC for ADC
|
|
using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
|
|
(++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
|
|
into the function of corresponding ADC interruption vector
|
|
ADCx_IRQHandler().
|
|
|
|
(#) Optionally, in case of usage of DMA:
|
|
(++) Configure the DMA (DMA channel, mode normal or circular, ...)
|
|
using function HAL_DMA_Init().
|

(++) Configure the NVIC for DMA
|
