程序中已经定义了复位，片选，时钟，即Sdata等信号的接口，应该使用了spi方式控制，
define CS_1 GpioDataRegs.GPADAT.bit.GPIO5=1 //GPIO5作为CS
#define CS_0 GpioDataRegs.GPADAT.bit.GPIO5=0 //GPIO5作为CS
#define SCLK_1 GpioDataRegs.GPADAT.bit.GPIO4=1 //GPIO4作为SCLK
#define SCLK_0 GpioDataRegs.GPADAT.bit.GPIO4=0 //GPIO4作为SCLK
#define SDATA_OUT GpioCtrlRegs.GPADIR.bit.GPIO2=1 //GPIO2作为SDATA
#define SDATA_IN GpioCtrlRegs.GPADIR.bit.GPIO2=0 //GPIO2作为SDATA
#define SDATA GpioDataRegs.GPADAT.bit.GPIO2
#define RST_1 GpioDataRegs.GPADAT.bit.GPIO3=1 //GPIO3做RST
#define RST_0 GpioDataRegs.GPADAT.bit.GPIO3=0 //GPIO3做RST
你这应该是合肥零零电子的例程，看谁有板子，原理图要过来直接连接就行了，反正你也懒得想
