| mbed_official | 340:28d1f895c6fe | 19 | |
| mbed_official | 340:28d1f895c6fe | 20 | [..] |
| mbed_official | 340:28d1f895c6fe | 21 | The STM32F0xx device family integrates up to 2 analog comparators COMP1 and COMP2: |
| mbed_official | 630:825f75ca301e | 22 | (+) The non inverting input and inverting input can be set to GPIO pins |
| mbed_official | 340:28d1f895c6fe | 23 | as shown in table1. COMP Inputs below. |
| mbed_official | 340:28d1f895c6fe | 24 | |
| mbed_official | 630:825f75ca301e | 25 | (+) The COMP output is available using HAL_COMP_GetOutputLevel() |
| mbed_official | 340:28d1f895c6fe | 26 | and can be set on GPIO pins. Refer to table 2. COMP Outputs below. |
| mbed_official | 340:28d1f895c6fe | 27 | |
| mbed_official | 630:825f75ca301e | 28 | (+) The COMP output can be redirected to embedded timers (TIM1, TIM2 and TIM3) |
| mbed_official | 340:28d1f895c6fe | 29 | Refer to table 3. COMP Outputs redirection to embedded timers below. |
| mbed_official | 340:28d1f895c6fe | 30 | |
| mbed_official | 630:825f75ca301e | 31 | (+) The comparators COMP1 and COMP2 can be combined in window mode. |
| mbed_official | 340:28d1f895c6fe | 32 | |
| mbed_official | 630:825f75ca301e | 33 | (+) The comparators have interrupt capability with wake-up |
| mbed_official | 340:28d1f895c6fe | 34 | from Sleep and Stop modes (through the EXTI controller): |
| mbed_official | 340:28d1f895c6fe | 35 | (++) COMP1 is internally connected to EXTI Line 21 |
| mbed_official | 340:28d1f895c6fe | 36 | (++) COMP2 is internally connected to EXTI Line 22 |
| mbed_official | 630:825f75ca301e | 37 | |
| mbed_official | 630:825f75ca301e | 38 | (+) From the corresponding IRQ handler, the right interrupt source can be retrieved with the |
| mbed_official | 630:825f75ca301e | 39 | macros __HAL_COMP_COMP1_EXTI_GET_FLAG() and __HAL_COMP_COMP2_EXTI_GET_FLAG(). |

| mbed_official | 340:28d1f895c6fe | 86 | ##### How to use this driver ##### |
| mbed_official | 340:28d1f895c6fe | 87 | ================================================================================ |
| mbed_official | 340:28d1f895c6fe | 88 | [..] |
| mbed_official | 441:d2c15dda23c1 | 89 | This driver provides functions to configure and program the Comparators of STM32F05x, STM32F07x and STM32F09x devices. |
| mbed_official | 340:28d1f895c6fe | 90 | |
| mbed_official | 340:28d1f895c6fe | 91 | To use the comparator, perform the following steps: |
| mbed_official | 340:28d1f895c6fe | 92 | |
| mbed_official | 340:28d1f895c6fe | 93 | (#) Fill in the HAL_COMP_MspInit() to |
| mbed_official | 340:28d1f895c6fe | 94 | (++) Configure the comparator input in analog mode using HAL_GPIO_Init() |
| mbed_official | 340:28d1f895c6fe | 95 | (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator |
| mbed_official | 340:28d1f895c6fe | 96 | output to the GPIO pin |
| mbed_official | 340:28d1f895c6fe | 97 | (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and |
| mbed_official | 340:28d1f895c6fe | 98 | selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator |
| mbed_official | 340:28d1f895c6fe | 99 | interrupt vector using HAL_NVIC_EnableIRQ() function. |
| mbed_official | 340:28d1f895c6fe | 100 | |
| mbed_official | 340:28d1f895c6fe | 101 | (#) Configure the comparator using HAL_COMP_Init() function: |
| mbed_official | 630:825f75ca301e | 102 | (++) Select the inverting input (input minus) |
| mbed_official | 630:825f75ca301e | 103 | (++) Select the non inverting input (input plus) |
| mbed_official | 340:28d1f895c6fe | 104 | (++) Select the output polarity |
| mbed_official | 340:28d1f895c6fe | 105 | (++) Select the output redirection |
| mbed_official | 340:28d1f895c6fe | 106 | (++) Select the hysteresis level |
| mbed_official | 340:28d1f895c6fe | 107 | (++) Select the power mode |
| mbed_official | 340:28d1f895c6fe | 108 | (++) Select the event/interrupt mode |
| mbed_official | 630:825f75ca301e | 109 | (++) Select the window mode |
| mbed_official | 340:28d1f895c6fe | 110 | |
| mbed_official | 630:825f75ca301e | 111 | -@@- HAL_COMP_Init() calls internally __HAL_RCC_SYSCFG_CLK_ENABLE() in order |
| mbed_official | 630:825f75ca301e | 112 | to access the comparator(s) registers. |
| mbed_official | 630:825f75ca301e | 113 | |
| mbed_official | 630:825f75ca301e | 114 | (#) Enable the comparator using HAL_COMP_Start() function or HAL_COMP_Start_IT() function for interrupt mode. |
| mbed_official | 340:28d1f895c6fe | 115 | |
| mbed_official | 630:825f75ca301e | 116 | (#) Use HAL_COMP_TriggerCallback() and/or HAL_COMP_GetOutputLevel() functions |
| mbed_official | 630:825f75ca301e | 117 | to manage comparator outputs (event/interrupt triggered and output level). |
| mbed_official | 630:825f75ca301e | 118 | |
| mbed_official | 630:825f75ca301e | 119 | (#) Disable the comparator using HAL_COMP_Stop() or HAL_COMP_Stop_IT() |
| mbed_official | 630:825f75ca301e | 120 | function. |
| mbed_official | 630:825f75ca301e | 121 | |
| mbed_official | 630:825f75ca301e | 122 | (#) De-initialize the comparator using HAL_COMP_DeInit() function. |
| mbed_official | 630:825f75ca301e | 123 | |
| mbed_official | 630:825f75ca301e | 124 | (#) For safety purposes comparator(s) can be locked using HAL_COMP_Lock() function. |
| mbed_official | 630:825f75ca301e | 125 | Only a MCU reset can reset that protection. |
