下图表示SPI RAM初始化成功。 下图信息说明,外部RAM可用的内存为4049k bytes,当freertos开始运行,进入main函数后,esp_get_free_heap_size()获取到的可用内存为4253k bytes,这是由内部RAM和外部RAM的所有可用的内存的总和,大概可知道可用的内部RAM只有约200k bytes。可见外部RAM极大的扩展了可用内存。 五,小结 由于...

使用xPortGetFreeHeapSize()、heap_caps_get_free_size()或相关函数来跟踪应用程序生命周期内的内存使用情况。尝试将泄漏缩小到单个函数或函数序列,在这些函数中,可用内存总是减少并且永远不会恢复。 一旦确定了正在泄漏的代码: ·在项目配置菜单中,导航到Component settings -> Heap Memory Debugging -> Heap tracing...
}//清理free(buffer); } HTTP 是协议层的,初始化时不用加载硬件驱动,所以它的仪式感就没那么强了。esp_http_client_config_t 结构体用于配置 HTTP 请求相关的信息。url 成员指定你要请求的URL,buffer_size 是esp处理传输数据的缓冲大小,不是你写代码时用的字节数组的大小。method 成员指定请求方式,如 GET、PO...

On the device below, I have disabled bluetooth coex, but bluetooth is enabled in the SDK configuration. The device is set up to use a 32k crystal, however the device in question does not have one, and falls back to the internal 150kHz oscillator on boot. ...
