青年是整个社会力量中的一部分最积极最有生气的力量。他们最肯学习，最少保守思想，在社会主义时代尤其是这样。——毛泽东
被朋友委托研究了新大陆的lora-nb通用库文件，在这里给大家分享一下，研究后的代码，考虑到朋友的学生，对软件和代码理解不深。先交大家两个在Keil uVision5中非常好用的方法。
方法一：跳转到对应的库文件，只需要双击全选函数或者头文件，然后点击键盘上的F12键或者右键选择"Open ....."或“Go To.....”(开头的选项就行)就能跳转到对应的库文件中，新大陆的库中都有注释。都要靠知己去找。去理解而不是一味的抄。
方法二：代码提示选项，其他的工具都有代码提示，比如java，python,php......等等。新大陆默认把代码提示给关闭掉了，一个字，恶心。现在教大家怎么操作。
上面看不懂的朋友，这个网址非常详细https://blog.csdn.net/sinat_26528193/article/details/113769716
接下来都是代码了

将代码复制下来粘贴进main文件里面就行然后烧写就行，代码主要还是要靠知己理解，库多翻翻就会简单，现在是显示图片。显示图片也是非常的简单。

OK今天就分享到这了。下一期是折线图。折线图也非常简单，他库中本来有函数可以调用的，结果代码好像被删掉了，或者被注释掉了，自己写一个也不难30行搞定。
