bogdanm 0:9b334a45a8ff 22 The STM32F3xx device family integrates up to 7 analog comparators COMP1, COMP2...COMP7:
bogdanm 0:9b334a45a8ff 23 (#) The non inverting input and inverting input can be set to GPIO pins
bogdanm 0:9b334a45a8ff 24 as shown in table1. COMP Inputs below for STM32F303xB/STM32F303xC as example.
bogdanm 0:9b334a45a8ff 25 For other STM32F3xx devices please refer to the COMP peripheral section in corresponding
bogdanm 0:9b334a45a8ff 26 Reference Manual.
bogdanm 0:9b334a45a8ff 27
bogdanm 0:9b334a45a8ff 28 (#) The COMP output is available using HAL_COMP_GetOutputLevel()
bogdanm 0:9b334a45a8ff 29 and can be set on GPIO pins. Refer to table 2. COMP Outputs below for STM32F303xB/STM32F303xC as example.
bogdanm 0:9b334a45a8ff 30 For other STM32F3xx devices please refer to the COMP peripheral section in corresponding
bogdanm 0:9b334a45a8ff 31 Reference Manual.
bogdanm 0:9b334a45a8ff 32
bogdanm 0:9b334a45a8ff 33 (#) The COMP output can be redirected to embedded timers (TIM1, TIM2, TIM3...)
bogdanm 0:9b334a45a8ff 34 Refer to table 3. COMP Outputs redirection to embedded timers below for STM32F303xB/STM32F303xC as example.
bogdanm 0:9b334a45a8ff 35 For other STM32F3xx devices please refer to the COMP peripheral section in corresponding

bogdanm 0:9b334a45a8ff 37
bogdanm 0:9b334a45a8ff 38 (#) The comparators COMP1 and COMP2, COMP3 and COMP4, COMP5 and COMP6 can be combined in window
bogdanm 0:9b334a45a8ff 39 mode and only COMP1, COMP3 and COMP5 non inverting input can be used as non-inverting input.
bogdanm 0:9b334a45a8ff 40
bogdanm 0:9b334a45a8ff 41 (#) The seven comparators have interrupt capability with wake-up
bogdanm 0:9b334a45a8ff 42 from Sleep and Stop modes (through the EXTI controller):
bogdanm 0:9b334a45a8ff 43 (++) COMP1 is internally connected to EXTI Line 21
bogdanm 0:9b334a45a8ff 44 (++) COMP2 is internally connected to EXTI Line 22

bogdanm 0:9b334a45a8ff 49 (++) COMP7 is internally connected to EXTI Line 33
bogdanm 0:9b334a45a8ff 50 From the corresponding IRQ handler, the right interrupt source can be retrieved with the
bogdanm 0:9b334a45a8ff 51 macro __HAL_COMP_EXTI_GET_FLAG(). Possible values are:

bogdanm 0:9b334a45a8ff 174 [..]
bogdanm 0:9b334a45a8ff 175 This driver provides functions to configure and program the Comparators of all STM32F3xx devices.
bogdanm 0:9b334a45a8ff 176
bogdanm 0:9b334a45a8ff 177 To use the comparator, perform the following steps:
bogdanm 0:9b334a45a8ff 178
bogdanm 0:9b334a45a8ff 179 (#) Fill in the HAL_COMP_MspInit() to
bogdanm 0:9b334a45a8ff 180 (++) Configure the comparator input in analog mode using HAL_GPIO_Init()
bogdanm 0:9b334a45a8ff 181 (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator
bogdanm 0:9b334a45a8ff 182 output to the GPIO pin
bogdanm 0:9b334a45a8ff 183 (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and
bogdanm 0:9b334a45a8ff 184 selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator
bogdanm 0:9b334a45a8ff 185 interrupt vector using HAL_NVIC_EnableIRQ() function.
bogdanm 0:9b334a45a8ff 186
bogdanm 0:9b334a45a8ff 187 (#) Configure the comparator using HAL_COMP_Init() function:
bogdanm 0:9b334a45a8ff 188 (++) Select the inverting input
bogdanm 0:9b334a45a8ff 189 (++) Select the non-inverting input
bogdanm 0:9b334a45a8ff 190 (++) Select the output polarity
bogdanm 0:9b334a45a8ff 191 (++) Select the output redirection
bogdanm 0:9b334a45a8ff 192 (++) Select the hysteresis level
bogdanm 0:9b334a45a8ff 193 (++) Select the power mode
bogdanm 0:9b334a45a8ff 194 (++) Select the event/interrupt mode
bogdanm 0:9b334a45a8ff 195
bogdanm 0:9b334a45a8ff 196 (#) Enable the comparator using HAL_COMP_Start() function or HAL_COMP_Start_IT() function for interrupt mode
