##### COMP Peripheral features #####

==============================================================================
|
||||
[..]
|
||||
The device integrates 7 analog comparators COMP1, COMP2...COMP7:
|
||||
(#) The non inverting input and inverting input can be set to GPIO pins
|
||||
as shown in table1. COMP Inputs below.
|
||||
|
||||
(#) The COMP output is internally is available using COMP_GetOutputLevel()
|
||||
and can be set on GPIO pins. Refer to table 2. COMP Outputs below.
|
||||
|
||||
(#) The COMP output can be redirected to embedded timers (TIM1, TIM2, TIM3...)
|
||||
Refer to table 3. COMP Outputs redirection to embedded timers below.
|
||||
|
||||
(#) The comparators COMP1 and COMP2, COMP3 and COMP4, COMP5 and COMP6 can be combined in window
|
||||
mode and only COMP1, COMP3 and COMP5 non inverting input can be used as non-inverting input.
|
||||
|
||||
(#) The seven comparators have interrupt capability with wake-up
|
||||
from Sleep and Stop modes (through the EXTI controller):
|
||||
(++) COMP1 is internally connected to EXTI Line 21
|
||||
(++) COMP2 is internally connected to EXTI Line 22
|
||||
(++) COMP3 is internally connected to EXTI Line 29
|
||||
(++) COMP4 is internally connected to EXTI Line 30
|
||||
(++) COMP5 is internally connected to EXTI Line 31
|
||||
(++) COMP6 is internally connected to EXTI Line 32
|
||||
(++) COMP7 is internally connected to EXTI Line 33

##### How to use this driver #####
|
||||
==============================================================================
|
||||
[..]
|
||||
This driver provides functions to configure and program the Comparators
|
||||
of all STM32F30x devices.
|
||||
|
||||
To use the comparator, perform the following steps:
|
||||
|
||||
(#) Enable the SYSCFG APB clock to get write access to comparator
|
||||
register using RCC_APB2PeriphClockCmd(RCC_APB2Periph_SYSCFG, ENABLE);
|
||||
|
||||
(#) Configure the comparator input in analog mode using GPIO_Init()
|
||||
|
||||
(#) Configure the comparator output in alternate function mode
|
||||
using GPIO_Init() and use GPIO_PinAFConfig() function to map the
|
||||
comparator output to the GPIO pin
|
||||
|
||||
(#) Configure the comparator using COMP_Init() function:
|
||||
(++) Select the inverting input
|
||||
(++) Select the non-inverting input
|
||||
(++) Select the output polarity
|
||||
(++) Select the output redirection
|
||||
(++) Select the hysteresis level
|
||||
(++) Select the power mode
|
||||
|
||||
(#) Enable the comparator using COMP_Cmd() function
|
||||
|
||||
(#) If required enable the COMP interrupt by configuring and enabling
|
||||
EXTI line in Interrupt mode and selecting the desired sensitivity
|
||||
level using EXTI_Init() function. After that enable the comparator
|
||||
interrupt vector using NVIC_Init() function.
