Mipi接口实际要是比我们的RGB接口复杂多了，关键目前我们MIPI接口就2lane导致很多的屏幕是选择不了的，所以官方这种用MIPI已经是为我们测试过了。接下来就跟着我们踩坑吧。
我们先看下框图，实际就是在GLCDC的基础上拓展了一个MIPI芯片，所以开始初始化就得初始化我们的GLCDC的管脚，所以这些管脚外接功能就不能使用了，实际就是内部连接了。
实际我们初始化的，我还是只初始化了我们引出的管脚，其他的管脚我未使用，我们其实无所谓这些，到mipi这边简化了。我理解565,666,888这些都能驱动屏幕。
之后还是要注意初始化SDRAM不然例程还是会有问题的。
踩坑第一就是这个电源电压，我理解的一般MIPI屏幕都是1.8V通信，所以我先接的1.8V的电阻，然后不亮，才发现是要接3.3V。
厂家原理图里面给的接口是3.3V。
接下来还是要修改里面的内容。首先还是得要厂家的驱屏参数。
输入用的RGB888模式。
输出参数需要对应屏幕参数。
输出这边我们就不用管大小端了，模式注意下我们最高666输出，目前根据屏幕配置的RGB565。
Mipi的配置简单点，基本都是默认，然后注意自己生成了一个回调函数，我们需要进行编写。
原本官方例程给了一个低功耗的操作，我这里直接删除，所以魔改了很多。
然后就是配置这里，我们需要问屏厂要这个资料，所以说配置麻烦的很，尤其是这个你要对比多次在你驱动不起来的情况下。
那个回调函数就是用来确定配置表是否发送到屏了。
成功驱动后的样子给看下：
后面还有摄像头接口，屏幕也是加了触摸，我们还可以做很多东西。
