mbed_official | 237:f3da66175598 | 81 | (#) Enable the ADC interface |
mbed_official | 237:f3da66175598 | 82 | As prerequisite, into HAL_ADC_MspInit(), ADC clock must be configured |
mbed_official | 237:f3da66175598 | 83 | at RCC top level: clock source and clock prescaler. |
mbed_official | 237:f3da66175598 | 84 | |
mbed_official | 237:f3da66175598 | 85 | For STM32F30x/STM32F33x devices: |
mbed_official | 237:f3da66175598 | 86 | Two possible clock sources: synchronous clock derived from AHB clock |
mbed_official | 237:f3da66175598 | 87 | or asynchronous clock derived from ADC dedicated PLL 72MHz. |
mbed_official | 237:f3da66175598 | 88 | |
mbed_official | 237:f3da66175598 | 89 | For example, in case of device with a single ADC: |
mbed_official | 237:f3da66175598 | 90 | __ADC1_CLK_ENABLE() (mandatory) |
mbed_official | 237:f3da66175598 | 91 | __HAL_RCC_ADC1_CONFIG(RCC_ADC1PLLCLK_DIV1); (optional) |

mbed_official | 237:f3da66175598 | 94 | if((hadc->Instance == ADC1) || (hadc->Instance == ADC2)) |
mbed_official | 237:f3da66175598 | 95 | { |
mbed_official | 237:f3da66175598 | 96 | __ADC12_CLK_ENABLE() (mandatory) |

mbed_official | 237:f3da66175598 | 4625 | * @note Possibility to update parameters on the fly: |
mbed_official | 237:f3da66175598 | 4626 | * This function initializes injected group, following calls to this |
mbed_official | 237:f3da66175598 | 4627 | * function can be used to reconfigure some parameters of structure |
mbed_official | 237:f3da66175598 | 4628 | * "ADC_InjectionConfTypeDef" on the fly, without reseting the ADC. |
mbed_official | 237:f3da66175598 | 4629 | * The setting of these parameters is conditioned to ADC state. |
mbed_official | 237:f3da66175598 | 4630 | * For parameters constraints, see comments of structure |
mbed_official | 237:f3da66175598 | 4631 | * "ADC_InjectionConfTypeDef". |
mbed_official | 237:f3da66175598 | 4632 | * @note In case of usage of internal measurement channels: |
mbed_official | 237:f3da66175598 | 4633 | * Vbat/VrefInt/TempSensor. |
mbed_official | 237:f3da66175598 | 4634 | * The recommended sampling time is at least: |
mbed_official | 237:f3da66175598 | 4635 | * - For devices STM32F37x: 17.1us for temperature sensor |
mbed_official | 237:f3da66175598 | 4636 | * - For the other STM32F3 devices: 2.2us for each of channels |
mbed_official | 237:f3da66175598 | 4637 | * Vbat/VrefInt/TempSensor. |
mbed_official | 237:f3da66175598 | 4638 | * These internal paths can be be disabled using function |
mbed_official | 237:f3da66175598 | 4639 | * HAL_ADC_DeInit(). |
mbed_official | 237:f3da66175598 | 4640 | * @note To reset injected sequencer, function HAL_ADCEx_InjectedStop() can |
mbed_official | 237:f3da66175598 | 4641 | * be used. |
mbed_official | 237:f3da66175598 | 4642 | * @note Caution: For Injected Context Queue use: a context must be fully |
mbed_official | 237:f3da66175598 | 4643 | * defined before start of injected conversion: all channels configured |
mbed_official | 237:f3da66175598 | 4644 | * consecutively for the same ADC instance. Therefore, Number of calls of |
mbed_official | 237:f3da66175598 | 4645 | * HAL_ADCEx_InjectedConfigChannel() must correspond to value of parameter |
mbed_official | 237:f3da66175598 | 4646 | * InjectedNbrOfConversion for each context. |
mbed_official | 237:f3da66175598 | 4647 | * - Example 1: If 1 context intended to be used (or not use of this feature: |
mbed_official | 237:f3da66175598 | 4648 | * QueueInjectedContext=DISABLE) and usage of the 3 first injected ranks |
mbed_official | 237:f3da66175598 | 4649 | * (InjectedNbrOfConversion=3), HAL_ADCEx_InjectedConfigChannel() must be |
mbed_official | 237:f3da66175598 | 4650 | * called once for each channel (3 times) before launching a conversion. |
mbed_official | 237:f3da66175598 | 4651 | * This function must not be called to configure the 4th injected channel: |
mbed_official | 237:f3da66175598 | 4652 | * it would start a new context into context queue. |
mbed_official | 237:f3da66175598 | 4653 | * - Example 2: If 2 contexts intended to be used and usage of the 3 first |
mbed_official | 237:f3da66175598 | 4654 | * injected ranks (InjectedNbrOfConversion=3), |
mbed_official | 237:f3da66175598 | 4655 | * HAL_ADCEx_InjectedConfigChannel() must be called once for each channel and |
mbed_official | 237:f3da66175598 | 4656 | * for each context (3 channels x 2 contexts = 6 calls). Conversion can |
mbed_official | 237:f3da66175598 | 4657 | * start once the 1st context is set. The 2nd context can be set on the fly. |
