前言

本文实现了使用GD32FF427V-START板子的SPI1驱动TFTLCD，LCD是2.2寸的ILI9341屏，不带触摸功能，这块屏幕是我从n年前参加兆易创新比赛获得的奖品GD32E230C-EVAL开发板上薅下来的，这块板子已经吃灰多年，没有派上什么用处，这次想起来还有这么一块板子，遂将LCD屏幕取下来，使用GD32F427V驱动试一下。
遗憾的是这块屏幕一直有一条蓝色的竖线，可能是放的时间太久了，电路有了断点。
本文实现功能如下：

基于RT-Thread Studio开发，基于RT-Thread OS；
使用SPI1驱动；
完成英文字符显示。

LCD屏资料

我手头并没有这块LCD屏幕的资料，遂到GD官网找了一番，还是没有，然后在万能的淘宝上才找到了资料。
资料网址：2.2inch SPI Module ILI9341 SKU: MSP2202

这个网址介绍的很详细，本文不做赘述。
下图是产品参数：

下图是引脚连接,引脚布局很重要，后面都需要连接到单片机上使用：

线路连接

知道了LCD的引脚布局，接下来就是与单片机连接了，这块LCD是SPI驱动的，所以我们需要选择一路SPI作为我们的驱动总线，本文选择了SPI1。
SPI硬件连接如下图，复用关系为AF5。

线路连接如下：

GD32F427V-START	TFTLCD Pin
3.3V	VCC
GND	GND
PB0	CS
PB1	RESET
PB12	DC/RS
PB15	SDI/MOSI
PB13	SCK
3.3V	LED
PB14	SDO/MISO

软件实现

软件也是在GD32E230C-EVAL板子提供的源码基础上修改而来的，适配了我定义的这几个引脚，，该驱动程序不止适用于该LCD，也适用于其他的ILI9341驱动芯片的屏幕。

驱动代码由三个文件组成：
app_tftlcd_drv.c；
app_tftlcd_drv.h；
app_tftlcd_font.h。

app_tftlcd_drv.c

该文件主要实现了spi1以及使用到的其他IO口的初始化以及LCD屏幕的驱动代码。
