自定义 esp_event_handler_register 例子,记得以前,刚开始入门学习Java的时候,看的是一个XX机构的教学视频。里面讲javase异常部分的老师说:“你们现在觉得异常捕获、抛出、打印,好像很简单,没有什么意义。但实际上,对异常的处理,很能体现一个程序员的水平。”当时懵
ESP_ERROR_CHECK(esp_event_handler_instance_register_with(event_loop, "custom_event_base", ESP_EVENT_ANY_ID, custom_event_handler, NULL, &instance)); ``` ### 步骤3:使用esp_event_handler_instance_register注册事件处理函数 现在,我们可以使用esp_event_handler_instance_register函数来注册事件处理函数...
esp_event_handler_instance_t位于esp_event_base.h中,是8个月前加入的,有没有可能你copy的example是从最新的idf上拿的,而编译用的IDF版本比较老? Post Reply 2 posts • Page1of1 Return to “ESP-IDF 中文讨论版” Jump to Who is online
bool EventloopHandler::postEventWithSize(esp_event_base_t eventBase, int32_t eventId, void* event_data, size_t event_data_size) { char buffer[event_data_size + sizeof(size_t) + sizeof(EVENTLOOP_MAGIC_NUMBER)]; *(size_t*)buffer = EVENTLOOP_MAGIC_NUMBER; *(size_t*)(buffer + si...
I call theesp_event_handler_instance_registeronly for the Wi-Fi start function: /** * \brief Connect to the Wi-Fi access point. * \note The SSID and pasword are in the 'station.h' file. */ static void start_station(void) { s_wifi_event_group = xEventGroupCreate(); //ESP_ERRO...
- When the GATT event handler on Core 1 sends the data to the queue, will uart_tx_task on Core 0 immediately be unblocked and start running, or will it only start running at the next tick interrupt? I know in a normal single core system, you would use the pxHigherPriorityTaskWoken ...

在Kubernetes(简称K8S)中,esp_event_handler_register是一个用于注册事件处理程序的函数。这个函数主要用于注册一个事件处理程序,当特定类型的事件发生时,这个事件处理程序将被调用。在本篇文章中,我将向你介绍如何使用esp_event_handler_register函数来实现事件处理,以及每一步需要做什么。

Might be a stupid question, but i'm new i all this esp32 sdk programming. What exactly is the event_handler in this function: Code: Select all esp_err_t event_handler(void *ctx, system_event_t *event) { return ESP_OK; } Why should i implement this function in the beginning of ...
