Raspberry Pi 2 B 型 v1.1 是否有内部 RTC? [英] Does the Raspberry Pi 2 model B v1.1 have an internal RTC?

问题描述

我使用 Raspberry Pi 2 B 型 v1.1，我搜索了一个 RTC，即使在停电或互联网连接中断的情况下也能保持时间.我发现必须买一块带电池的RTC芯片.但是最近我听说我的 Raspberry Pi 已经包含一个 RTC.但这是对的吗?如果有，它的位置在哪里?我的芯片上没有看到任何称为 RTC 的东西.

I work with Raspberry Pi 2 model B v1.1 and I searched about a RTC to keep time even in the case of a power outage or a loss of internet connection. I found that I must buy a RTC chip with a battery. But recently I heard that my Raspberry Pi already contains a RTC. But is it right? If so, where is its location? I don't see anything called RTC on my chip.

推荐答案

我相当肯定没有内置 RTC 芯片:Pi 用户的抱怨之一是没有内置硬件时钟皮."(来源:https://www.element14.com/community/community/raspberry-pi/raspberry-pi-accessories/blog/2015/04/22/raspberry-pi-2-piface-rtc-shim-testing).

I am fairly certain there is not an RTC chip built-in: "One of the complaints Pi users have is that there's no built-in hardware clock on the Pi." (Source: https://www.element14.com/community/community/raspberry-pi/raspberry-pi-accessories/blog/2015/04/22/raspberry-pi-2-piface-rtc-shim-testing).

但是，我找到了一个不错的 教程关于如何安装自己的.

However, I was able to find a nice tutorial on how to install your own.
