In this ESP-IDF series of tutorials, we will introduce you to ESP timer API by going through an example (system/esp_timer) provided by ESP-IDF. This high resolution timer APIs feature the creation of multiple timers though a a single hardware timer. Several timers can easily be managed thr...
esp32的组件(components)里面的esp_timer提供了软件定时器相关api,支持周期回调、单词回调等操作。其中软件定时器的初始化在void start_cpu0_default(void)函数中调用esp_timer_init()。 2、API 2.1、定时器配置结构体 代码语言:javascript 复制 typedef struct{esp_timer_cb_t callback;//回调函数void*arg;//参...

这是esp_timer创建时所需参数的结构体,结构体成员有5个成员 第一个是当定时器到达设定值时回调函数的地址。 第二个是回调函数的传递参数 第三个是调用回调函数的方式,是从task中回调还是从ISR中回调,esp32目前只支持task中回调。所以不用设置 第四个是定时器的名字 ...
