mbed_official | 181:a4cbdfbbd2f4 | 21 | [..] |
mbed_official | 181:a4cbdfbbd2f4 | 22 | The STM32L0xx device family integrates 2 analog comparators COMP1 and COMP2: |
mbed_official | 181:a4cbdfbbd2f4 | 23 | (#) The non inverting input and inverting input can be set to GPIO pins |
mbed_official | 181:a4cbdfbbd2f4 | 24 | as shown in table1. COMP Inputs below. |
mbed_official | 181:a4cbdfbbd2f4 | 25 | |
mbed_official | 181:a4cbdfbbd2f4 | 26 | (#) The COMP output is available using HAL_COMP_GetOutputLevel() |
mbed_official | 181:a4cbdfbbd2f4 | 27 | and can be set on GPIO pins. Refer to table 2. COMP Outputs below. |
mbed_official | 181:a4cbdfbbd2f4 | 28 | |
mbed_official | 181:a4cbdfbbd2f4 | 29 | (#) The COMP output can be redirected to embedded timers (TIM2, TIM21, TIM22...) and LPTIM |
mbed_official | 181:a4cbdfbbd2f4 | 30 | Refer to TIM and LPTIM drivers. |
mbed_official | 181:a4cbdfbbd2f4 | 31 | |
mbed_official | 181:a4cbdfbbd2f4 | 32 | (#) The comparators COMP1 and COMP2 can be combined in window mode and only COMP2 non inverting input can be used as non-inverting input. |
mbed_official | 181:a4cbdfbbd2f4 | 33 | |
mbed_official | 181:a4cbdfbbd2f4 | 34 | (#) The 2 comparators have interrupt capability with wake-up |
mbed_official | 181:a4cbdfbbd2f4 | 35 | from Sleep and Stop modes (through the EXTI controller): |
mbed_official | 181:a4cbdfbbd2f4 | 36 | (++) COMP1 is internally connected to EXTI Line 21 |
mbed_official | 181:a4cbdfbbd2f4 | 37 | (++) COMP2 is internally connected to EXTI Line 22 |
mbed_official | 181:a4cbdfbbd2f4 | 38 | |
mbed_official | 181:a4cbdfbbd2f4 | 39 | From the corresponding IRQ handler, the right interrupt source can be retrieved with the |
mbed_official | 181:a4cbdfbbd2f4 | 40 | macro __HAL_COMP_EXTI_GET_FLAG(). Possible values are: |
mbed_official | 181:a4cbdfbbd2f4 | 41 | (++) COMP_EXTI_LINE_COMP1_EVENT |
mbed_official | 181:a4cbdfbbd2f4 | 42 | (++) COMP_EXTI_LINE_COMP2_EVENT |

mbed_official | 181:a4cbdfbbd2f4 | 75 | ##### How to use this driver ##### |
mbed_official | 181:a4cbdfbbd2f4 | 76 | ================================================================================ |
mbed_official | 181:a4cbdfbbd2f4 | 77 | [..] |
mbed_official | 181:a4cbdfbbd2f4 | 78 | This driver provides functions to configure and program the Comparators of all STM32L0xx devices. |
mbed_official | 181:a4cbdfbbd2f4 | 79 | |
mbed_official | 181:a4cbdfbbd2f4 | 80 | To use the comparator, perform the following steps: |
mbed_official | 181:a4cbdfbbd2f4 | 81 | |
mbed_official | 181:a4cbdfbbd2f4 | 82 | (#) Initialize the COMP low level resources by implementing the HAL_COMP_MspInit(). |
mbed_official | 181:a4cbdfbbd2f4 | 83 | (++) Enable the SYSCFG APB clock to get write access to comparator register using __SYSCFG_CLK_ENABLE(). |
mbed_official | 181:a4cbdfbbd2f4 | 84 | (++) Configure the comparator input in analog mode using HAL_GPIO_Init(). |
mbed_official | 181:a4cbdfbbd2f4 | 85 | (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator |
mbed_official | 181:a4cbdfbbd2f4 | 86 | output to the GPIO pin. |
mbed_official | 181:a4cbdfbbd2f4 | 87 | (++) If required enable the VREFINT reference using HAL_VREFINT_Cmd() and HAL_COMP_EnableBuffer_Cmd(). |
mbed_official | 181:a4cbdfbbd2f4 | 88 | (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and |
mbed_official | 181:a4cbdfbbd2f4 | 89 | selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator |
mbed_official | 181:a4cbdfbbd2f4 | 90 | interrupt vector using HAL_NVIC_EnableIRQ() function. |
mbed_official | 181:a4cbdfbbd2f4 | 91 | |
mbed_official | 181:a4cbdfbbd2f4 | 92 | (#) Configure the comparator using HAL_COMP_Init() function: |
mbed_official | 181:a4cbdfbbd2f4 | 93 | (++) Select the inverting input |
mbed_official | 181:a4cbdfbbd2f4 | 94 | (++) Select the non-inverting input |
mbed_official | 181:a4cbdfbbd2f4 | 95 | (++) Select the output polarity |
mbed_official | 181:a4cbdfbbd2f4 | 96 | (++) Select the power mode |
mbed_official | 181:a4cbdfbbd2f4 | 97 | (++) Select the window mode |
mbed_official | 181:a4cbdfbbd2f4 | 98 | |
mbed_official | 181:a4cbdfbbd2f4 | 99 | (#) Enable the comparator using HAL_COMP_Start() function |
