mbed_official 237:f3da66175598 22 The STM32F3xx device family integrates up to 7 analog comparators COMP1, COMP2...COMP7:
mbed_official 237:f3da66175598 23 (#) The non inverting input and inverting input can be set to GPIO pins
mbed_official 237:f3da66175598 24 as shown in table1. COMP Inputs below for STM32F303xB/STM32F303xC as example.
mbed_official 237:f3da66175598 25 For other STM32F3xx devices please refer to the COMP peripheral section in corresponding
mbed_official 237:f3da66175598 26 Reference Manual.
mbed_official 237:f3da66175598 27
mbed_official 237:f3da66175598 28 (#) The COMP output is available using HAL_COMP_GetOutputLevel()
mbed_official 237:f3da66175598 29 and can be set on GPIO pins. Refer to table 2. COMP Outputs below for STM32F303xB/STM32F303xC as example.

mbed_official 237:f3da66175598 37
mbed_official 237:f3da66175598 38 (#) The comparators COMP1 and COMP2, COMP3 and COMP4, COMP5 and COMP6 can be combined in window
mbed_official 237:f3da66175598 39 mode and only COMP1, COMP3 and COMP5 non inverting input can be used as non-inverting input.
mbed_official 237:f3da66175598 40
mbed_official 237:f3da66175598 41 (#) The seven comparators have interrupt capability with wake-up

mbed_official 237:f3da66175598 129 ##### How to use this driver #####
mbed_official 237:f3da66175598 130 ================================================================================
mbed_official 237:f3da66175598 131 [..]
mbed_official 237:f3da66175598 132 This driver provides functions to configure and program the Comparators of all STM32F3xx devices.
mbed_official 237:f3da66175598 133
mbed_official 237:f3da66175598 134 To use the comparator, perform the following steps:
mbed_official 237:f3da66175598 135
mbed_official 237:f3da66175598 136 (#) Fill in the HAL_COMP_MspInit() to
mbed_official 237:f3da66175598 137 (++) Configure the comparator input in analog mode using HAL_GPIO_Init()
mbed_official 237:f3da66175598 138 (++) Configure the comparator output in alternate function mode using HAL_GPIO_Init() to map the comparator
mbed_official 237:f3da66175598 139 output to the GPIO pin
mbed_official 237:f3da66175598 140 (++) If required enable the COMP interrupt by configuring and enabling EXTI line in Interrupt mode and
mbed_official 237:f3da66175598 141 selecting the desired sensitivity level using HAL_GPIO_Init() function. After that enable the comparator
mbed_official 237:f3da66175598 142 interrupt vector using HAL_NVIC_EnableIRQ() function.
mbed_official 237:f3da66175598 143
mbed_official 237:f3da66175598 144 (#) Configure the comparator using HAL_COMP_Init() function:
mbed_official 237:f3da66175598 145 (++) Select the inverting input
mbed_official 237:f3da66175598 146 (++) Select the non-inverting input
mbed_official 237:f3da66175598 147 (++) Select the output polarity
mbed_official 237:f3da66175598 148 (++) Select the output redirection
mbed_official 237:f3da66175598 149 (++) Select the hysteresis level
mbed_official 237:f3da66175598 150 (++) Select the power mode
mbed_official 237:f3da66175598 151 (++) Select the event/interrupt mode
mbed_official 237:f3da66175598 152
mbed_official 237:f3da66175598 153 (#) Enable the comparator using HAL_COMP_Start() function or HAL_COMP_Start_IT() function for interrupt mode
mbed_official 237:f3da66175598 154
mbed_official 237:f3da66175598 155 (#) Read the comparator output level with HAL_COMP_GetOutputLevel()
