DA14531定时器1捕获

你好！

我试图与SmartSnippets开发环境，熟悉自己的新用户。我正在使用：

DEV-套件：DA14531-00FXDEVKT-P
SDK：6.0.12.1020

现在我需要测量脉冲的数量在一定时间内，约1200个脉冲10ms.According官方网站上的例子“da14531_timer1_software_example”，我一直在使用定时器1的捕捉功能成功地测量正确的脉冲数。

"user_timer1.c"相关代码片段如下所示:

#include " user_timestamp .h" #include " user_timestamp .h" #include " user_timestamp .h" #include " user_timestamp .h" #include " user_timestamp .h" #include " user_timestamp .h" #include " user_timestamp .h" #include " user_timestamp .h"bool c_flag = 0;//Timer1 capture / period count配置结构static timer1_event_options_t timer1_event_1 ={/*每个事件存储的时间戳类型*/ .stamp_type = TIM1_EVENT_STAMP_CNT， /*统计的周期数*/ .period_count = 100， /*Timer1事件IRQ掩码*/ .irq_mask = TIM1_EVENT_IRQ_MASK_OFF，/*Timer1 event type*/ .event_type = TIM1_EVENT_TYPE_CAP， /*Timer1 edge type*/ .edge_type = TIM1_EVENT_EDGE_RISING， /*GPIO pin to be monitoring */ .gpio_pin = TIM1_EVENT_GPIO_PIN_3，};Static void timer1_event1_user_callback_function(void) {c_flag=1;数+ +;SetBits32 (TIMER1_CLR_EVENT_REG TIMER1_CLR_IN1_EVENT 1);} /** **************************************************************************************** * @ 短暂Timer1设置捕获finction * @param[在]void * @return空白  **************************************************************************************** */ 空白timer1_capturing_setup(){/ /开始Timer1 timer1_start ();//启用SWTIM_IRQn irq timer1_enable_irq();//为SWTIM_IRQn配置和注册Timer1回调函数irq timer1_event1_config(&timer1_event_1,timer1_event1_user_callback_function); }

传感器脉冲在GPIO_PIN_3引脚上捕获，每到达一个上升边计数增加1。每个周期测量的脉冲数约为1126。

不过，我需要通过蓝牙技术“灯塔”广播脉冲数，所以我试图代码合并到“da14531-da14585-586_Simple灯塔示例”的网站。但是，当我完成了移植和运行程序，我发现认为“定时器1”无法捕捉的pulses.The捕获脉冲数几十间跳跃正确的号码和两个程序之间的两百hundred.The“user_timer1.c”是identical.I把脉冲数据处理代码在主function.The特定的一段时间（1）循环的开始相关的代码如下：

对于“da14531-da14585-586_simple_beacon_example”，我没有更改代码的其余部分。我刚刚注释掉了“da1458x_config_basic.h”文件中的“#define CFG_WDOG”。然后删除arch_main.c文件，并添加一个新的main.c文件，内容相同。

我感到困惑的是，相同的代码片段在“da14531_timer1_software_example”中可以正常工作，而在“da14531-da14585-586_simple_beacon_example”中则不行。而当我先烧掉“da14531_timer1_software_example”，再烧掉“da14531_timer1_software_example”时，脉冲的数量也会不正确，只有30多个。程序“da14531_timer1_software_example”中捕获的脉冲数恢复正常，充电后达到1000多个。

我附上了这两个项目的结果。

非常感谢帮助。
