phungductung 0:8ede47d38d10 14 ==============================================================================
phungductung 0:8ede47d38d10 15 [..]
phungductung 0:8ede47d38d10 16 (#)Initialize the ADC low level resources by implementing the HAL_ADC_MspInit():
phungductung 0:8ede47d38d10 17 (##) Enable the ADC interface clock using __HAL_RCC_ADC_CLK_ENABLE()
phungductung 0:8ede47d38d10 18 (##) ADC pins configuration
phungductung 0:8ede47d38d10 19 (+++) Enable the clock for the ADC GPIOs using the following function:
phungductung 0:8ede47d38d10 20 __HAL_RCC_GPIOx_CLK_ENABLE()
phungductung 0:8ede47d38d10 21 (+++) Configure these ADC pins in analog mode using HAL_GPIO_Init()
phungductung 0:8ede47d38d10 22 (##) In case of using interrupts (e.g. HAL_ADC_Start_IT())
phungductung 0:8ede47d38d10 23 (+++) Configure the ADC interrupt priority using HAL_NVIC_SetPriority()
phungductung 0:8ede47d38d10 24 (+++) Enable the ADC IRQ handler using HAL_NVIC_EnableIRQ()
phungductung 0:8ede47d38d10 25 (+++) In ADC IRQ handler, call HAL_ADC_IRQHandler()
phungductung 0:8ede47d38d10 26 (##) In case of using DMA to control data transfer (e.g. HAL_ADC_Start_DMA())
phungductung 0:8ede47d38d10 27 (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE()
phungductung 0:8ede47d38d10 28 (+++) Configure and enable two DMA streams stream for managing data
phungductung 0:8ede47d38d10 29 transfer from peripheral to memory (output stream)

phungductung 0:8ede47d38d10 31 using __HAL_LINKDMA()
phungductung 0:8ede47d38d10 32 (+++) Configure the priority and enable the NVIC for the transfer complete
phungductung 0:8ede47d38d10 33 interrupt on the two DMA Streams. The output stream should have higher
phungductung 0:8ede47d38d10 34 priority than the input stream.
phungductung 0:8ede47d38d10 35 (#) Configure the ADC Prescaler, conversion resolution and data alignment
phungductung 0:8ede47d38d10 36 using the HAL_ADC_Init() function.
phungductung 0:8ede47d38d10 37
phungductung 0:8ede47d38d10 38 (#) Configure the ADC Injected channels group features, use HAL_ADC_Init()
phungductung 0:8ede47d38d10 39 and HAL_ADC_ConfigChannel() functions.
phungductung 0:8ede47d38d10 40
phungductung 0:8ede47d38d10 41 (#) Three operation modes are available within this driver :
