<p>rtc.h:</p>

<p>3、在主程序中添加日历显示代码：</p>
<pre>
<code> while (1)
{
if(rtc_status == 1)
{
rtc_status = 0;
RTC_TimeShow();
RTC_GetTime(RTC_FORMAT_BIN, &RTC_TimeStructure);

<p>定时60秒钟更新一次显示。</p>

<p>感谢大佬关注。国民技术这块蓝牙芯片，目前感觉是非常好的一款。</p>
<p>墨水屏看着就是舒服，点赞收藏 </p>
<p>没有体验体验蓝牙吗？ </p>

没有体验体验蓝牙吗？
<p>正在学习之中呀，蓝牙的例程看了好久，还没有整明白呀。</p>
秦天qintian0303 发表于 2023-5-8 17:05
没有体验体验蓝牙吗？
<p>我是在想是不是整个蓝牙在线设置时间的。现在还有低功耗唤醒没有解决好。</p>
