很奇怪的一件事

我用官方文档搬了这串代码，刚开始有一个指针设置错误了，屏幕是可以显示的，但是会每隔1秒左右重启一次。修好这个Bug之后屏幕就不亮了。我再次用官方的example烧录进去，是可以正常显示的。于是我尝试把example里的代码搬过来改动，发现也是不能显示的，查看monitor并没有任何异常。这是怎么回事呢？

刚开始有一个指针设置错误了，屏幕是可以显示的，但是会每隔1秒左右重启一次。修好这个Bug之后屏幕就不亮了。
修改的是哪里？
屏幕就只是亮还会正常显示？

我再次用官方的example烧录进去，是可以正常显示的。于是我尝试把example里的代码搬过来改动，发现也是不能显示的，查看monitor并没有任何异常。这是怎么回事呢？
example 和 自己工程的区别是设么， 是否方便提供完整工程？
