It follows their earlier STR9 family based on the ARM9E core, and STR7 family based on the ARM7TDMI core. ![]() TimerInitStructure.The STM32 is the third ARM family by STMicroelectronics. TimerInitStructure.TIM_ClockDivision = TIM_CKD_DIV1 TimerInitStructure.TIM_CounterMode = TIM_CounterMode_Up TimerInitStructure.TIM_Prescaler = 40000 TIM_TimeBaseInitTypeDef timerInitStructure RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE) GPIO_WriteBit(GPIOD, GPIO_Pin_12 | GPIO_Pin_13, Bit_RESET) GpioStructure.GPIO_Speed = GPIO_Speed_50MHz GpioStructure.GPIO_Pin = GPIO_Pin_12 | GPIO_Pin_13 RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOD, ENABLE) Note that before we can do anything with the timer we need to enable it by calling RCC_APB1PeriphClockCmd(): We will initialize the timer to run with a prescaler of 40000, and a period of 500.The timer will automatically reset itself to zero once it reaches a value of 500: Let’s start with a simple program that will configure the timer to run in the background with a period of 500, turn the LED on once the value reaches 400 and back off once it gets to 500.It runs in the background independently from your C/C++ program and its value typically follows the sequence depicted below: A hardware timer is essentially an independent counter that counts from zero to its maximum value at a given speed and generates various events.by following this tutorial for STM32F1 series devices or this tutorial for the STM32F4-Discovery board). To learn about controlling the timers using the new HAL interface, follow this tutorial instead.īefore you begin with this tutorial please create a basic project for your STM32 device (e.g. Warning: this tutorial describes the legacy StdPeriph interface. We will show it based on the STM32F4-Discovery board, however controlling the timers of other STM32 devices is very similar. This tutorial shows how control the hardware timers of an STM32 microcontroller. ![]()
