### 2.4 启用 NTP 时间自动同步
|
||||
|
||||
如果 RT-Thread 已接入互联网,可启用 NTP 时间自动同步功能,定期同步本地时间。
|
||||
|
||||
在 menuconfig 中启用 `RTC_SYNC_USING_NTP` 配置。启用该功能后,会自动开启 [netutils package](https://github.com/RT-Thread-packages/netutils) 的 NTP 功能。同时务必确保 RT-Thread 网络访问正常。
|
||||
|
||||
启用该配置后,还有两个配置是用户可选配置:
|
||||
|
||||
- `RTC_NTP_FIRST_SYNC_DELAY`: 首次执行 NTP 时间同步的延时。延时的目的在于,给网络连接预留一定的时间,尽量提高第一次执行 NTP 时间同步时的成功率。默认时间为 30S;
|
||||
- `RTC_NTP_SYNC_PERIOD`: NTP 自动同步周期,单位为秒,默认一小时(即 3600S)同步一次。
|
||||
|
||||
> 注意:如果没有使用组件自动初始化功能,则需手动调用 `int rt_rtc_ntp_sync_init(void)` ,完成该功能初始化。
|
||||
|
||||
### 2.5 启用 Soft RTC (软件模拟 RTC)
|
||||
### 2.4 启用 Soft RTC (软件模拟 RTC)
|
||||
|
||||
这个模式非常适用于对时间精度要求不高,没有硬件 RTC 的产品。
|
||||
|
||||
#### 2.5.1 使用方法
|
||||
#### 2.4.1 使用方法
|
||||
|
||||
在 menuconfig 中启用 `RT_USING_SOFT_RTC` 配置。
|
||||
|
||||
> 注意:如果没有使用组件自动初始化功能,则需手动调用 `int rt_soft_rtc_init(void)` ,完成该功能初始化。
