2.2寸（14PIN）TFT液晶屏STM32 SPI 控制

屏幕如图所示，共14个IO口（也可能只有13个），控制屏幕的有9个IO口

详细版介绍见：http://www.ciast.net/post/20151112.html

反面IO口图：

连接通过SPI方式连接：

//默认程序接线说明：
#define LCD_CTRL             GPIOB                //定义TFT数据端口为PB组
#define LCD_LED            GPIO_Pin_9  //MCU_PB9           对应接液晶屏(或者模块)TFT --PIN_LED背光正极（背光可以由IO口提供电流，或者外接3.3V电压）
#define LCD_CS            GPIO_Pin_11 //MCU_PB11            对应接液晶屏(或者模块)TFT --CS
#define LCD_SCL            GPIO_Pin_13    //MCU_PB13            对应接液晶屏(或者模块)TFT --SCL
#define LCD_SDA            GPIO_Pin_15    //MCU_PB15 MOSI    对应接液晶屏(或者模块)TFT --SDA
#define LCD_SDO            GPIO_Pin_14    //MCU_PB14 MISO    对应接液晶屏(或者模块)TFT --SDO
#define LCD_RS             GPIO_Pin_10    //MCU_PB10            对应接液晶屏(或者模块)TFT --RS/DC
#define LCD_RST           GPIO_Pin_12    //MCU_PB12            对应接液晶屏(或者模块)TFT --RST
