并且通过利用RT-ThreadStudio加快编译开发AB32的环境,使得整体开发效率较高。 rt-thread提供了丰富的软件包可以直接使用,其系统架构也是采用了系统与应用分层的设计思想,使得开发者不用关注底层架构的具体实现细节,包括也不需要特别对riscv架构有很深刻的理解也能够快速上手。这对于嵌入式应用开发者来说非常的友好,在现...
vtaskdelay() causes the GPIO# assigned in esp_sleep_enable_ext0_wakeup(GPIO#, high) to immediately go high. (Behavior is observed via o-scope.) When the device goes to deep sleep, the device is immediately awaken with the wakeup cause "ext0 wakeup". Removing the vtaskdelay() ...
In my ESP32-S3 code I noticed that in my main loop I have to add `vTaskDelay(1)` otherwise I get a wdt reset. I guess this is because if I don't suspend for a while my thread, the others cannot run. Since `CONFIG_FREERTOS_HZ` is defined as 100, a delay of just 1 tick ...

Calling vTaskDelay takes ~ 0.5 [ms]? Because when vTaskDelay exits, the time is on a tick boundary. Immediately after, important_function is called, which uses some time, which I'm rounding to half a tick. (The exact duration doesn't matter, simply that it is less than a whole ...
vTaskDelay(pdMS_TO_TICKS(2000)); }//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...
