获取毫秒级时间 和普通系统函数相同
int get_sys_time_ms(void) { struct timeval tv_now; gettimeofday(tv_now, NULL); int64_t time_us (int64_t)tv_now.tv_sec * 1000000L (int64_t)tv_now.tv_usec; return (int)(time_us/1000); } 2、延时毫秒级时间
void my_delay_ms(u32 time_ms) { vTaskDelay(time_ms / portTICK_RATE_MS); } SNTP校时 SNTP 指 简单网络时间协议Simple Network Time Protocol一个合格的物联网设备少不了一个准确的钟。通过SNTP可以使ESP32设备通过网络校准本地时间。 最简单基础的方式
sntp_setoperatingmode(SNTP_OPMODE_POLL); sntp_setservername(0, ntp.aliyun.com); sntp_init(); 但此时你的ESP32要联网否则肯定是获取不了
接下来你可以通过sntp_get_sync_status()轮询检测同步是否完毕官方示例提供了这样的代码。除此之外。我们也可以通过回调来完成。更新成功之后就随时可以获取系统时间了
首先设置时区方法这只影响下文时间转换不影响时间同步。如果你有自己的方法则可以通过自己的方式设置
设置时区---时区缩写 当sntp成功同步时间后会有一个异步的回调通知应用做出相应更改
sntp_set_time_sync_notification_cb(/* 需要的函数指针 /);
初始化实例
static void esp_initialize_sntp(void)
{ESP_LOGI(esp32idf_title, Initializing SNTP);sntp_setoperatingmode(SNTP_OPMODE_POLL);sntp_setservername(0, ntp1.aliyun.com);sntp_setservername(1, cn.ntp.org.cn); // 设置访问服务器sntp_setservername(2, pool.ntp.org);sntp_setservername(3, 210.72.145.44); // 国家授时中心服务器 IP 地址sntp_init();
}
