关于ESP32定时器运行报错的问题

[zhaidayu]

void my_timer_init(void)
{
timer_config_t timer_config_str;
timer_config_str.divider = timer_divider; //分频值，默认时钟是80mhz,80mhz/80=1mhz=1us
timer_config_str.counter_dir = TIMER_COUNT_UP;//向上计数模式
timer_config_str.counter_en = TIMER_PAUSE;//定时器计数失能
timer_config_str.alarm_en = TIMER_ALARM_EN;//使能定时器报警
timer_config_str.intr_type = TIMER_INTR_LEVEL;//定时器中断模式为电平模式
timer_config_str.auto_reload = 1; //使能自动装载
/*!<Hw timer group 0*/
/*!<Select timer0 of GROUPx*/
timer_init(TIMER_GROUP_0,TIMER_0,&timer_config_str);//esp32定时器共有两组，每组两个

timer_set_counter_value(TIMER_GROUP_0, TIMER_0, 0);//设置定时器的计数值
timer_set_alarm_value(TIMER_GROUP_0, TIMER_0, timer_go_handler);//设置定时器的报警值(进入中断的值)
timer_enable_intr(TIMER_GROUP_0, TIMER_0);//使能定时器中断
timer_isr_callback_add(TIMER_GROUP_0, TIMER_0, my_isr_handler, NULL,0);//添加定时器中断回调
timer_start(TIMER_GROUP_0, TIMER_0);//打开定时器
}

void IRAM_ATTR my_isr_handler(void)
{
timer_count++;
timer_count_value = timer_group_get_counter_value_in_isr(TIMER_GROUP_0,TIMER_0);
}

这个使用的时候编译没有错误，下载进板子之后就会一直报错，一直重启，报错内容如下
Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0).

callback 应该是要求返回的bool类型的，不知道为什么你的代码居然能够编译通过。另外建议你参考master上的example,代码有清理过，比以前清晰简单：https://github.com/espressif/esp-idf/tr ... acy_driver
