TIM4->SR!=0
时间: 2024-05-24 10:13:34 浏览: 18
This code checks if the status register (SR) of the TIM4 timer is not equal to zero. The TIM4 timer is a hardware timer in microcontrollers that can be used for various timing and counting operations. The SR register contains various status flags that indicate the current status of the timer. By checking if the SR register is not equal to zero, the code can determine if any of these status flags are set, indicating that a particular event has occurred or a certain condition has been met.

TIM10->SR = 0x03
TIM10->SR = 0x03是STM32中定时器TIM10的状态寄存器(SR)的赋值操作。这个操作的含义是将TIM10的状态寄存器中的中断标志位清零,其中0x03表示清除TIM10的更新中断标志和触发中断标志。定时器中断是在定时器计数满或者比较事件发生时被触发的,通过清除中断标志位可以避免重复触发中断。
TIM4->SR什么意思
引用\[1\]中的代码片段是一个中断处理函数,其中涉及到了TIM3的相关操作。TIM4->SR是指TIM4的状态寄存器,SR是Status Register的缩写。在这个上下文中,TIM4->SR表示对TIM4的状态进行读取或写入操作。具体来说,SR的每一位都代表了不同的状态标志位,用于表示不同的事件或中断。通过读取或写入SR寄存器,可以对这些状态标志位进行操作,例如清除中断标志位或检查某个事件是否发生。
