(#) 16-bit programmable prescaler allowing dividing (also on the fly) the counter clock frequency either by any factor between 1 and 65536. (#) Up to 4 independent channels for: (++) Input Capture (++) Output Compare (++) PWM generation (Edge and Center-aligned Mode) (++) One-pulse mode output ##### How to use this driver ##### ============================================================================== [..] (#) Initialize the TIM low level resources by implementing the following functions depending on the selected feature: (++) Time Base : HAL_TIM_Base_MspInit() (++) Input Capture : HAL_TIM_IC_MspInit() (++) Output Compare : HAL_TIM_OC_MspInit() (++) PWM generation : HAL_TIM_PWM_MspInit() (++) One-pulse mode output : HAL_TIM_OnePulse_MspInit() (++) Encoder mode output : HAL_TIM_Encoder_MspInit() (#) Initialize the TIM low level resources : (##) Enable the TIM interface clock using __HAL_RCC_TIMx_CLK_ENABLE(); (##) TIM pins configuration (+++) Enable the clock for the TIM GPIOs using the following function: __HAL_RCC_GPIOx_CLK_ENABLE(); (+++) Configure these TIM pins in Alternate function mode using HAL_GPIO_Init(); (#) The external Clock can be configured, if needed (the default clock is the internal clock from the APBx), using the following function: HAL_TIM_ConfigClockSource, the clock configuration should be done before any start function. (#) Configure the TIM in the desired functioning mode using one of the Initialization function of this driver: (++) HAL_TIM_Base_Init: to use the Timer to generate a simple time base (++) HAL_TIM_OC_Init and HAL_TIM_OC_ConfigChannel: to use the Timer to generate an Output Compare signal. (++) HAL_TIM_PWM_Init and HAL_TIM_PWM_ConfigChannel: to use the Timer to generate a PWM signal. (++) HAL_TIM_IC_Init and HAL_TIM_IC_ConfigChannel: to use the Timer to measure an external signal. (++) HAL_TIM_OnePulse_Init and HAL_TIM_OnePulse_ConfigChannel: to use the Timer in One Pulse Mode. (++) HAL_TIM_Encoder_Init: to use the Timer Encoder Interface. (#) Activate the TIM peripheral using one of the start functions depending from the feature used: (++) Time Base : HAL_TIM_Base_Start(), HAL_TIM_Base_Start_DMA(), HAL_TIM_Base_Start_IT() (++) Input Capture : HAL_TIM_IC_Start(), HAL_TIM_IC_Start_DMA(), HAL_TIM_IC_Start_IT() (++) Output Compare : HAL_TIM_OC_Start(), HAL_TIM_OC_Start_DMA(), HAL_TIM_OC_Start_IT() (++) PWM generation : HAL_TIM_PWM_Start(), HAL_TIM_PWM_Start_DMA(), HAL_TIM_PWM_Start_IT() (++) One-pulse mode output : HAL_TIM_OnePulse_Start(), HAL_TIM_OnePulse_Start_IT() (++) Encoder mode output : HAL_TIM_Encoder_Start(), HAL_TIM_Encoder_Start_DMA(), HAL_TIM_Encoder_Start_IT(). (#) The DMA Burst is managed with the two following functions: HAL_TIM_DMABurst_WriteStart() HAL_TIM_DMABurst_ReadStart() @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2016 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
