RTTV4.04.使用stduio+cube配置。 配置TIM3正常使用,使用TIM1卡死在rt_thread_mdelay延时处。 rt_thread_mdelay延时的时钟使用SYS或者TIM6都卡在这。 怀疑是优先级的问题,更改TIM1定时器优先级最低也没有用。 board。h中定义
#define BSP_USING_TIM #ifdef BSP_USING_TIM #define BSP_USING_TIM1 #ifdef BSP_USING_TIM1 #ifndef TIM1_CONFIG #define TIM1_CONFIG { .tim_handle.Instance = TIM1, .tim_irqn = TIM1_UP_TIM10_IRQn, .name = "timer1", } #endif /* TIM1_CONFIG/ #endif /TIM1_CONFIG/ #define BSP_USING_TIM3 #ifdef BSP_USING_TIM3 #ifndef TIM3_CONFIG #define TIM3_CONFIG { .tim_handle.Instance = TIM3, .tim_irqn = TIM3_IRQn, .name = "timer3", } #endif /TIM3_CONFIG/ #endif /BSP_USING_TIM3 */ 官方例程只改了设备名

- 程序清单:这是一个 hwtimer 设备使用例程
- 例程导出了 hwtimer_sample 命令到控制终端
- 命令调用格式:hwtimer_sample
- 程序功能:硬件定时器超时回调函数周期性的打印当前tick值,2次tick值之差换算为时间等同于定时时间值。
