| mbed_official | 218:44081b78fdc2 | 22 | The STM32F0xx device family integrates up to 2 analog comparators COMP1 and COMP2: |
| mbed_official | 205:c41fc65bcfb4 | 23 | (#) The non inverting input and inverting input can be set to GPIO pins |
| mbed_official | 205:c41fc65bcfb4 | 24 | as shown in table1. COMP Inputs below. |
| mbed_official | 205:c41fc65bcfb4 | 25 | |
| mbed_official | 205:c41fc65bcfb4 | 26 | (#) The COMP output is available using HAL_COMP_GetOutputLevel() |
| mbed_official | 205:c41fc65bcfb4 | 27 | and can be set on GPIO pins. Refer to table 2. COMP Outputs below. |
| mbed_official | 205:c41fc65bcfb4 | 28 | |
| mbed_official | 205:c41fc65bcfb4 | 29 | (#) The COMP output can be redirected to embedded timers (TIM1, TIM2 and TIM3) |
| mbed_official | 205:c41fc65bcfb4 | 30 | Refer to table 3. COMP Outputs redirection to embedded timers below. |
| mbed_official | 205:c41fc65bcfb4 | 31 | |
| mbed_official | 205:c41fc65bcfb4 | 32 | (#) The comparators COMP1 and COMP2 can be combined in window mode. |
| mbed_official | 205:c41fc65bcfb4 | 33 | |
| mbed_official | 205:c41fc65bcfb4 | 34 | (#) The comparators have interrupt capability with wake-up |
| mbed_official | 205:c41fc65bcfb4 | 35 | from Sleep and Stop modes (through the EXTI controller): |
| mbed_official | 205:c41fc65bcfb4 | 36 | (++) COMP1 is internally connected to EXTI Line 21 |
| mbed_official | 205:c41fc65bcfb4 | 37 | (++) COMP2 is internally connected to EXTI Line 22 |
| mbed_official | 205:c41fc65bcfb4 | 38 | From the corresponding IRQ handler, the right interrupt source can be retrieved with the |
| mbed_official | 205:c41fc65bcfb4 | 39 | macro __HAL_COMP_EXTI_GET_FLAG(). Possible values are: |
| mbed_official | 205:c41fc65bcfb4 | 40 | (++) COMP_EXTI_LINE_COMP1_EVENT |

| mbed_official | 205:c41fc65bcfb4 | 89 | ================================================================================ |
| mbed_official | 205:c41fc65bcfb4 | 90 | [..] |
| mbed_official | 205:c41fc65bcfb4 | 91 | This driver provides functions to configure and program the Comparators of STM32F05x and STM32F07x devices. |
| mbed_official | 205:c41fc65bcfb4 | 92 | |
| mbed_official | 205:c41fc65bcfb4 | 93 | To use the comparator, perform the following steps: |
| mbed_official | 205:c41fc65bcfb4 | 94 | |
| mbed_official | 205:c41fc65bcfb4 | 95 | (#) Fill in the HAL_COMP_MspInit() to |
| mbed_official | 205:c41fc65bcfb4 | 96 | (++) Configure the comparator input in analog mode using HAL_GPIO_Init() |
| mbed_official | 205:c41fc65bcfb4 | 97 | (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator |
| mbed_official | 205:c41fc65bcfb4 | 98 | output to the GPIO pin |
| mbed_official | 205:c41fc65bcfb4 | 99 | (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and |
| mbed_official | 205:c41fc65bcfb4 | 100 | selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator |
| mbed_official | 205:c41fc65bcfb4 | 101 | interrupt vector using HAL_NVIC_EnableIRQ() function. |
| mbed_official | 205:c41fc65bcfb4 | 102 | |
| mbed_official | 205:c41fc65bcfb4 | 103 | (#) Configure the comparator using HAL_COMP_Init() function: |
| mbed_official | 205:c41fc65bcfb4 | 104 | (++) Select the inverting input |
| mbed_official | 205:c41fc65bcfb4 | 105 | (++) Select the output polarity |
| mbed_official | 205:c41fc65bcfb4 | 106 | (++) Select the output redirection |
| mbed_official | 205:c41fc65bcfb4 | 107 | (++) Select the hysteresis level |
| mbed_official | 205:c41fc65bcfb4 | 108 | (++) Select the power mode |
| mbed_official | 218:44081b78fdc2 | 109 | (++) Select the event/interrupt mode |
| mbed_official | 205:c41fc65bcfb4 | 110 | |
| mbed_official | 218:44081b78fdc2 | 111 | (#) Enable the comparator using HAL_COMP_Start() function or HAL_COMP_Start_IT() function for interrupt mode |
| mbed_official | 218:44081b78fdc2 | 112 | |
| mbed_official | 218:44081b78fdc2 | 113 | (#) Read the comparator output level with HAL_COMP_GetOutputLevel() |
