mbed_official | 205:c41fc65bcfb4 | 55 | ##### How to use this driver ##### |
mbed_official | 205:c41fc65bcfb4 | 56 | ============================================================================== |
mbed_official | 205:c41fc65bcfb4 | 57 | [..] |
mbed_official | 205:c41fc65bcfb4 | 58 | |
mbed_official | 205:c41fc65bcfb4 | 59 | (#) Enable the ADC interface |
mbed_official | 205:c41fc65bcfb4 | 60 | As prerequisite, into HAL_ADC_MspInit(), ADC clock must be configured |
mbed_official | 205:c41fc65bcfb4 | 61 | at RCC top level: clock source and clock prescaler. |
mbed_official | 205:c41fc65bcfb4 | 62 | Two possible clock sources: synchronous clock derived from APB clock |
mbed_official | 205:c41fc65bcfb4 | 63 | or asynchronous clock derived from ADC dedicated HSI RC oscillator |
mbed_official | 205:c41fc65bcfb4 | 64 | 14MHz. |
mbed_official | 205:c41fc65bcfb4 | 65 | Example: |
mbed_official | 205:c41fc65bcfb4 | 66 | __ADC1_CLK_ENABLE(); (mandatory) |
mbed_official | 205:c41fc65bcfb4 | 67 | |
mbed_official | 205:c41fc65bcfb4 | 68 | HI14 enable or let under control of ADC: (optional) |
mbed_official | 205:c41fc65bcfb4 | 69 | |
mbed_official | 205:c41fc65bcfb4 | 70 | RCC_OscInitTypeDef RCC_OscInitStructure; |
mbed_official | 205:c41fc65bcfb4 | 71 | RCC_OscInitStructure.OscillatorType = RCC_OSCILLATORTYPE_HSI14; |
mbed_official | 205:c41fc65bcfb4 | 72 | RCC_OscInitStructure.HSI14CalibrationValue = RCC_HSI14CALIBRATION_DEFAULT; |
mbed_official | 205:c41fc65bcfb4 | 73 | RCC_OscInitStructure.HSI14State = RCC_HSI14_ADC_CONTROL; |
mbed_official | 205:c41fc65bcfb4 | 74 | RCC_OscInitStructure.PLL... (optional if used for system clock) |
mbed_official | 205:c41fc65bcfb4 | 75 | HAL_RCC_OscConfig(&RCC_OscInitStructure); |
mbed_official | 205:c41fc65bcfb4 | 76 | |
mbed_official | 205:c41fc65bcfb4 | 77 | Parameter "HSI14State" must be set either: |
mbed_official | 205:c41fc65bcfb4 | 78 | - to "...HSI14State = RCC_HSI14_ADC_CONTROL" to let the ADC control |
mbed_official | 205:c41fc65bcfb4 | 79 | the HSI14 oscillator enable/disable (if not used to supply the main |
mbed_official | 205:c41fc65bcfb4 | 80 | system clock): feature used if ADC mode LowPowerAutoPowerOff is |
mbed_official | 205:c41fc65bcfb4 | 81 | enabled. |
mbed_official | 205:c41fc65bcfb4 | 82 | - to "...HSI14State = RCC_HSI14_ON" to maintain the HSI14 oscillator |
mbed_official | 205:c41fc65bcfb4 | 83 | always enabled: can be used to supply the main system clock. |
mbed_official | 205:c41fc65bcfb4 | 84 | |
mbed_official | 205:c41fc65bcfb4 | 85 | (#) ADC pins configuration |
mbed_official | 205:c41fc65bcfb4 | 86 | (++) Enable the clock for the ADC GPIOs using the following function: |
mbed_official | 205:c41fc65bcfb4 | 87 | __GPIOx_CLK_ENABLE(); |
mbed_official | 205:c41fc65bcfb4 | 88 | (++) Configure these ADC pins in analog mode using HAL_GPIO_Init(); |
mbed_official | 205:c41fc65bcfb4 | 89 | |
mbed_official | 205:c41fc65bcfb4 | 90 | (#) Configure the ADC parameters (conversion resolution, data alignment, |
mbed_official | 205:c41fc65bcfb4 | 91 | continuous mode, ...) using the HAL_ADC_Init() function. |
mbed_official | 205:c41fc65bcfb4 | 92 | |
mbed_official | 205:c41fc65bcfb4 | 93 | (#) Activate the ADC peripheral using one of the start functions: |
mbed_official | 205:c41fc65bcfb4 | 94 | HAL_ADC_Start(), HAL_ADC_Start_IT(), HAL_ADC_Start_DMA(). |
mbed_official | 205:c41fc65bcfb4 | 95 | |
mbed_official | 205:c41fc65bcfb4 | 96 | *** Channels to regular group configuration *** |
mbed_official | 205:c41fc65bcfb4 | 97 | ============================================ |
mbed_official | 205:c41fc65bcfb4 | 98 | [..] |
mbed_official | 205:c41fc65bcfb4 | 99 | (+) To configure the ADC regular group features, use |
mbed_official | 205:c41fc65bcfb4 | 100 | HAL_ADC_Init() and HAL_ADC_ConfigChannel() functions. |
mbed_official | 205:c41fc65bcfb4 | 101 | (+) To activate the continuous mode, use the HAL_ADC_Init() function. |
mbed_official | 205:c41fc65bcfb4 | 102 | (+) To read the ADC converted values, use the HAL_ADC_GetValue() function. |
mbed_official | 205:c41fc65bcfb4 | 103 | |
mbed_official | 205:c41fc65bcfb4 | 104 | *** DMA for regular configuration *** |
mbed_official | 205:c41fc65bcfb4 | 105 | ============================================================= |
mbed_official | 205:c41fc65bcfb4 | 106 | [..] |
mbed_official | 205:c41fc65bcfb4 | 107 | (+) To enable the DMA mode for regular group, use the |
mbed_official | 205:c41fc65bcfb4 | 108 | HAL_ADC_Start_DMA() function. |
mbed_official | 205:c41fc65bcfb4 | 109 | (+) To enable the generation of DMA requests continuously at the end of |
mbed_official | 205:c41fc65bcfb4 | 110 | the last DMA transfer, use the HAL_ADC_Init() function. |
