一，TFT屏硬件接口
16位，80并口。
二，FMC介绍。
FSMC（Flexible Static Memory Controller），译为灵活的静态存储控制器。STM32F1 系列芯片使用 FSMC 外设来管理扩展的存储器，它可以用于驱动包括 SRAM、NOR FLASH 以及 NAND FLSAH 类型的存储器，不能驱动如 SDRAM 这种动态的存储器而在 STM32F429 系列的控制器中，它具有 FMC 外设，支持控制 SDRAM 存储器。
由于 FSMC 外设可以用于控制扩展的外部存储器，而 MCU 对液晶屏的操作实际上就是把显示数据写入到显存中，与控制存储器非常类似，且 8080 接口的通讯时序完全可以使用 FSMC 外设产生，因而非常适合使用 FSMC 控制液晶屏。

三，STM32CubeIDE设置
设置FMC之前，先配置GPIO引脚，不然可能不能配置FMC，可能吧。
