如题所示。屏幕现在只能竖着看，我想横着显示内容 TFT为德飞来开发板给的。

所有的点阵字库都是以列为单元，也就是说，字库数据中的每一个字节就是一列的点阵。 转置 90 度有两种方法： 1 事先转换字库数据，行列互换，生成一个新的横向字库。 2 在显示的时候实现转换，要改写底层显示函数，增加转置处理。

“或者，从生成字模数据下手。。。”+1 字模图片旋转90度后再取模， 反正屛有认识字，最终在屛上显示的都图片。

[学习笔记] TFT_LCD彩屏 ST7735S驱动 画面水平翻转
最近在调试中景园的一款ST7735S驱动方式的LCD彩屏时，由于设计需求，需要把画面水平翻转显示。 通过中景园提供的代码，不难发现控制屏幕方向、旋转寄存器的地址为：36H 初始化程序中：头文件中： 通过USE_HORIZONTAL宏定义来控制屏幕的显示方向，但是中景园提供的代码里面没有关于水平翻转的设置，于是从中景园的资料中找到ST7735S的datasheet，其中36H对应寄存器的详解如下： 不难发现这三位bit决定了LCD屏的读写方向 通过不断的尝试配置这三位bit，最终发现要实现水平.
