- * @file at32f4xx_comp.c
- * @author Artery
- * @version V1.0.1
- * @date 20-April-2012
- * @brief This file provides firmware functions to manage the following
- * functionalities of the comparators (COMP1 and COMP2) peripheral:
- * + Comparators configuration
- * + Window mode control
- *
- * @verbatim
- *
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
-
- The device integrates two analog comparators COMP1 and COMP2:
- (+) The non inverting input is set to PA1 for COMP1 and to PA3
- for COMP2.
-
- (+) The inverting input can be selected among: DAC_OUT1,
- 1/4 VREFINT, 1/2 VERFINT, 3/4 VREFINT, VREFINT,
- I/O (PA0 for COMP1 and PA2 for COMP2)
-
- (+) The COMP output is internally is available using COMP_GetOutputState()
- and can be set on GPIO pins: PA0, PA6, PA11 for COMP1
- and PA2, PA7, PA12 for COMP2
-
- (+) The COMP output can be redirected to embedded timers (TIM1, TIM2
- and TIM3)
-
- (+) The two comparators COMP1 and COMP2 can be combined in window
- mode and only COMP1 non inverting (PA1) can be used as non-
- inverting input.
-
- (+) The two comparators COMP1 and COMP2 have interrupt capability
- with wake-up from Sleep and Stop modes (through the EXTI controller).
- COMP1 and COMP2 outputs are internally connected to EXTI Line 21
- and EXTI Line 22 respectively.
-
-
- ##### How to configure the comparator #####
- ===============================================================================
- [..]
- This driver provides functions to configure and program the Comparators
- of all AT32F4xx 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 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.
