我上周开始使用ESP32，目前我正试图将BLE iBeacon和1秒警报计时器的示例代码放在一起。当运行程序时，我收到错误abort() was called at PC 0x403774b7 on core 0 0x403774b7: lock_acquire_generic at /home/boko/esp/esp-idf/components/newlib/locks.c:130。我在计时器回调timer_alarm_cb中有一个ESP_LOGI()语句，这似乎导致了这个问题，但我不知道为什么和如何(如果我删除语句，程序工作正常)。我想用代码实现的是每1秒获得一次调试打印作为视觉反馈，以便知道在1秒间隔内检测到多少和哪些iBeacons。
我的两个问题是:
- 为什么定时器回调中的ESP_LOGI()语句会导致程序中止?
- 在ESP32中使用计时器每1秒获得调试打印的正确方法是什么?
我的代码是

您正在尝试从通用定时器中断中进行日志记录。引用日志库文档:
这个函数或这些宏不应该在中断中使用。
还有一个更长的评论，来自一个espresso的开发人员解释了为什么。似乎有另一个宏ESP_DRAM_LOGE用于从中断中打印(这通常不是一个好主意)。
无论如何，除了最严格的实时标准，我建议使用高分辨率计时器。它仍然在硬件计时器外设上运行，但是回调的处理被延迟到专用计时器任务(是的，您必须等待很短的时间，直到调度器开始执行该任务)。这意味着您的回调在常规任务中运行，并且可以调用日志函数。不要太过——你仍然希望延迟的计时器回调是相当快的，以避免时间抖动。
