/** ****************************************************************************** * @file stm32f4xx_tim.c * @author MCD Application Team * @version V1.0.2 * @date 05-March-2012 * @brief This file provides firmware functions to manage the following * functionalities of the TIM peripheral: * - TimeBase management * - Output Compare management * - Input Capture management * - Advanced-control timers (TIM1 and TIM8) specific features * - Interrupts, DMA and flags management * - Clocks management * - Synchronization management * - Specific interface management * - Specific remapping management * * @verbatim * * =================================================================== * How to use this driver * =================================================================== * This driver provides functions to configure and program the TIM * of all STM32F4xx devices. * These functions are split in 9 groups: * * 1. TIM TimeBase management: this group includes all needed functions * to configure the TM Timebase unit: * - Set/Get Prescaler * - Set/Get Autoreload * - Counter modes configuration * - Set Clock division * - Select the One Pulse mode * - Update Request Configuration * - Update Disable Configuration * - Auto-Preload Configuration * - Enable/Disable the counter * * 2. TIM Output Compare management: this group includes all needed * functions to configure the Capture/Compare unit used in Output * compare mode: * - Configure each channel, independently, in Output Compare mode * - Select the output compare modes * - Select the Polarities of each channel * - Set/Get the Capture/Compare register values * - Select the Output Compare Fast mode * - Select the Output Compare Forced mode * - Output Compare-Preload Configuration * - Clear Output Compare Reference * - Select the OCREF Clear signal * - Enable/Disable the Capture/Compare Channels * * 3. TIM Input Capture management: this group includes all needed * functions to configure the Capture/Compare unit used in * Input Capture mode: * - Configure each channel in input capture mode * - Configure Channel1/2 in PWM Input mode * - Set the Input Capture Prescaler * - Get the Capture/Compare values * * 4. Advanced-control timers (TIM1 and TIM8) specific features * - Configures the Break input, dead time, Lock level, the OSSI, * the OSSR State and the AOE(automatic output enable) * - Enable/Disable the TIM peripheral Main Outputs * - Select the Commutation event * - Set/Reset the Capture Compare Preload Control bit * * 5. TIM interrupts, DMA and flags management * - Enable/Disable interrupt sources * - Get flags status * - Clear flags/ Pending bits * - Enable/Disable DMA requests * - Configure DMA burst mode * - Select CaptureCompare DMA request * * 6. TIM clocks management: this group includes all needed functions * to configure the clock controller unit: * - Select internal/External clock * - Select the external clock mode: ETR(Mode1/Mode2), TIx or ITRx * * 7. TIM synchronization management: this group includes all needed * functions to configure the Synchronization unit: * - Select Input Trigger * - Select Output Trigger * - Select Master Slave Mode * - ETR Configuration when used as external trigger * * 8. TIM specific interface management, this group includes all * needed functions to use the specific TIM interface: * - Encoder Interface Configuration * - Select Hall Sensor * * 9. TIM specific remapping management includes the Remapping * configuration of specific timers * * @endverbatim * ****************************************************************************** * @attention * * <h2><center>&copy; COPYRIGHT 2012 STMicroelectronics</center></h2> * * Licensed under MCD-ST Liberty SW License Agreement V2, (the "License"); * You may not use this file except in compliance with the License. * You may obtain a copy of the License at: * * http://www.st.com/software_license_agreement_liberty_v2 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. * ****************************************************************************** */ /* Includes ------------------------------------------------------------------*/ #include "stm32f4xx_tim.h" #include "stm32f4xx_rcc.h" /** @addtogroup STM32F4xx_StdPeriph_Driver * @{ */ /** @defgroup TIM * @brief TIM driver modules * @{ */ /* Private typedef -----------------------------------------------------------*/ /* Private define ------------------------------------------------------------*/ /* ---------------------- TIM registers bit mask ------------------------ */ #define SMCR_ETR_MASK ((uint16_t)0x00FF) #define CCMR_OFFSET ((uint16_t)0x0018) #define CCER_CCE_SET ((uint16_t)0x0001) #define CCER_CCNE_SET ((uint16_t)0x0004) #define CCMR_OC13M_MASK ((uint16_t)0xFF8F) #define CCMR_OC24M_MASK ((uint16_t)0x8FFF) /* Private macro -------------------------------------------------------------*/ /* Private variables ---------------------------------------------------------*/ /* Private function prototypes -----------------------------------------------*/ static void TI1_Config(TIM_TypeDef* TIMx, uint16_t TIM_ICPolarity, uint16_t TIM_ICSelection, uint16_t TIM_ICFilter); static void TI2_Config(TIM_TypeDef* TIMx, uint16_t TIM_ICPolarity, uint16_t TIM_ICSelection, uint16_t TIM_ICFilter); static void TI3_Config(TIM_TypeDef* TIMx, uint16_t TIM_ICPolarity, uint16_t TIM_ICSelection, uint16_t TIM_ICFilter); static void TI4_Config(TIM_TypeDef* TIMx, uint16_t TIM_ICPolarity, uint16_t TIM_ICSelection, uint16_t TIM_ICFilter); /* Private functions ---------------------------------------------------------*/ /** @defgroup TIM_Private_Functions * @{ */ /** @defgroup TIM_Group1 TimeBase management functions * @brief TimeBase management functions * @verbatim ===============================================================================
