The STM32 Timer example program shows how to configure and use the timer TIM1 of STMicroelectronics STM32F103xx microcontroller. TIM1 is configured to generate an update interrupt every 250 ms. The lit LED moves on every timer tick. The configuration of
Timers can be used to trigger a variety of interrupts (see section 72.2.9 of theHAL/LL API reference documentfor a list of possible HAL-supported interrupt callbacks). We will use a very basic interrupt: when the timer reaches its maximum value, it will rollover back to ...

原文:To generate a multi-shot timer with a period of N processor clock cycles, use a RELOAD value of N-1. For example, if the SysTick interrupt is required every 100 clock pulses, set RELOAD to 99 要生成一个周期为N个处理器时钟周期的多触发定时器,请使用RELOADN-1的值。例如,如果每100个...
