使用ESP32可以成功获取到网络时间,怎么才能得到整形数据呢?我想显示到数码管上,谢谢大家!
#include <WiFi.h>

const char* ntpServer = "pool.ntp.org";
const long gmtOffset_sec = 28800;
const int daylightOffset_sec = 28800;
void smartConfig()
{
WiFi.mode(WIFI_STA);
Serial.println("\r\nWait for Smartconfig");
delay(2000);// 等待配网
WiFi.beginSmartConfig();
while (1)
{
Serial.print(".");
delay(500);
if (WiFi.smartConfigDone())
{
Serial.println("SmartConfig Success");
Serial.printf("SSID:%s\r\n", WiFi.SSID().c_str());
Serial.printf("PSW:%s\r\n", WiFi.psk().c_str());
WiFi.setAutoConnect(true); // 设置自动连接
break;

Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());

void printLocalTime()

if(!getLocalTime(&timeinfo))

已经顺利实现时间的显示
做的比较丑陋大家不要笑话
代码也分享出来
实现了自动配网
手机需要下载ESPTOUCH这个软件

可以到B站搜一下ESP32 有很多视频可以参考 我是自己搞着好玩的
