mbed_official 87:085cde657901 15 [..]
mbed_official 87:085cde657901 16 (#)Initialize the ADC low level resources by implementing the HAL_ADC_MspInit():
mbed_official 87:085cde657901 17 (##) Enable the ADC interface clock using __ADC_CLK_ENABLE()
mbed_official 87:085cde657901 18 (##) ADC pins configuration
mbed_official 87:085cde657901 19 (+++) Enable the clock for the ADC GPIOs using the following function:
mbed_official 87:085cde657901 20 __GPIOx_CLK_ENABLE()
mbed_official 87:085cde657901 21 (+++) Configure these ADC pins in analog mode using HAL_GPIO_Init()
mbed_official 87:085cde657901 22 (##) In case of using interrupts (e.g. HAL_ADC_Start_IT())
mbed_official 87:085cde657901 23 (+++) Configure the ADC interrupt priority using HAL_NVIC_SetPriority()
mbed_official 87:085cde657901 24 (+++) Enable the ADC IRQ handler using HAL_NVIC_EnableIRQ()
mbed_official 87:085cde657901 25 (+++) In ADC IRQ handler, call HAL_ADC_IRQHandler()
mbed_official 87:085cde657901 26 (##) In case of using DMA to control data transfer (e.g. HAL_ADC_Start_DMA())
mbed_official 226:b062af740e40 27 (+++) Enable the DMAx interface clock using __DMAx_CLK_ENABLE()
mbed_official 226:b062af740e40 28 (+++) Configure and enable two DMA streams stream for managing data
mbed_official 87:085cde657901 29 transfer from peripheral to memory (output stream)
mbed_official 226:b062af740e40 30 (+++) Associate the initilalized DMA handle to the ADC DMA handle
mbed_official 87:085cde657901 31 using __HAL_LINKDMA()
mbed_official 226:b062af740e40 32 (+++) Configure the priority and enable the NVIC for the transfer complete
mbed_official 87:085cde657901 33 interrupt on the two DMA Streams. The output stream should have higher
mbed_official 226:b062af740e40 34 priority than the input stream.
mbed_official 87:085cde657901 35 (#) Configure the ADC Prescaler, conversion resolution and data alignment
