arduino - ESP32-WROOM - 使用多核的问题

Question

我的 ESP32 Wroom 代码有问题。我正在尝试使用 esp 上的两个内核来加速并为设备创建一个高效的进程；一个核心检查来自网站页面的更改/响应。另一个根据收到的响应更改 LED 模式。

Core 0（得到响应）应该不断更新一个名为“payload”的字符串，其中包含来自网站的最新接收信息。这发生在另一个核心显示模式直到它接收到“有效负载”的变化时；并相应改变。

我遇到的问题是 esp 在上传和第一次启动后每 1-2 秒打印一次以下消息：

rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:1
load:0x3fff0018,len:4 
load:0x3fff001c,len:1044 
load:0x40078000,len:8896
load:0x40080400,len:5816
entry 0x400806ac

这也打印在一些消息中：

大师冥想错误：核心 0 恐慌（双重例外）

我是 ESP32 的新手，对 Arduino 没有太多经验，有人知道我做错了什么或避免当前问题实现相同目标的方法吗？提前致谢。

这是我的项目的代码。
