AiCube 编译错误请教，在 ercircle大侠指导下问题已经解决

一个已经在STC32G12K128成功驱动的LCD12864程序，


想移植到AICuber 的环境利用硬件SPI来串行硬件SPI驱动LCD12864

在中函数中声明了字库：


//<<AICUBE_USER_INCLUDE_BEGIN>>
// 在此添加用户头文件包含
#include "public.h"
#include "lcd12864.h"
#include "tupian.h"
//<<AICUBE_USER_INCLUDE_END>>



//<<AICUBE_USER_GLOBAL_DEFINE_BEGIN>>
// 在此添加用户全局变量定义、用户宏定义以及函数声明
extern u8 code ascii_table_8x16; //8*16字符
extern u8 code ascii_table_5x7;      //5*7字符
//<<AICUBE_USER_GLOBAL_DEFINE_END>>


编译的时候报错：

可以确定不是编译器所报的地方错（compiling lcdl2864.c...
App\ lcd12864\ tupian.h(7): error C142: illegal initialization App\ lcdl2864\ tupian.h(76) warning C34: 'u8: missing declaration specifiersl App\ lcd12864\ tupian.h(76): error C42: 'u8': not in formal parameter list）

这个字库文件所在的整个工程项目已经是成功点亮LCD，字库本身是没问题的，那么在AiCube下是怎样解决这个报错呢？

烦请哪位大神指点，谢谢谢谢谢谢！

错误信息“app\lcd12864\tupian.h(7): error c142: illegal initialization”，
推断出在文件app\lcd12864\tupian.h的第7行存在非法的初始化语句。这可能是由于数组初始化的方式不正确，或者是初始化的值超出了变量类型的范围，但是这个数组，乃至整个
tupian.h，已经在STC32G12K128 C251 Keil 环境下编译过正常运行了

我们之间打开tupian.h

谢谢指导！

另外我现在需要把下图中的SCLK和MOSI脚互换

就是我的LCD脚位是GND   VCC   SDA(MOSI）    SCLK            RS(DC)          RSTB(RES)    CSB(CS) 和试验箱的脚位，中间4位是反的：

         试验箱脚位是GND   VCC      SCLK       MOSI(SDA）   RES(RSTB)       DC(RS)       CS (CSB)


研究了很久，发现主要是 SCLK和   MOSI(SDA）这2位，硬件驱动SPI的话，一定要对应，其他2位，可以直接在程序中更改IO口

读试验箱图纸，有这样一句话：使用 SPI接口屏时设置为 P33-MOSI_4、P34-MISO_4
MOSI_4、MISO_4可以互换设置，请参考数据手册

再查例子程序77-DMA SPI刷新OLED12864显示屏程序，SSD1306驱动，0.96寸\test.uvproj-μVision

中有这样一段：


//******************************************
void Initialize_OLED(void)        //initialize OLED
{
        SPI_Config(3, 0);        //(SPI_io, SPI_speed), 参数:         SPI_io: 切换IO(SS MOSI MISO SCLK), 0: 切换到P1.4 P1.5 P1.6 P1.7,1: 切换到P2.4 P2.5 P2.6 P2.7, 2: 切换到P4.0 P4.1 P4.2 P4.3,3: 切换到P3.5 P3.4 P3.3 P3.2,
                                                //                                                                SPI_speed: SPI的速度, 0: fosc/4,1: fosc/8,2: fosc/16,3: fosc/2
        HSSPI_CFG2 = 0x40;        //交换MOSI MISO, P3.3是MOSI

        P1n_standard(Pin1);                        // SPI引脚设置为准双向口, SPI和控制信号
        PullUpEnable(P1PU, Pin1);        // 允许端口内部上拉电阻   PxPU, 要设置的端口对应位为1
        P3n_standard(0x2c);                        // SPI引脚设置为准双向口, SPI和控制信号
        PullUpEnable(P3PU, 0x2c);        // 允许端口内部上拉电阻   PxPU, 要设置的端口对应位为1
        P4n_standard(Pin7);                        // SPI引脚设置为准双向口, SPI和控制信号
        PullUpEnable(P4PU, Pin7);        // 允许端口内部上拉电阻   PxPU, 要设置的端口对应位为1


其中        HSSPI_CFG2 = 0x40;        //交换MOSI MISO, P3.3是MOSI
好像是交换交换MOSI MISO，但是查手册，HSSPI_CFG2 是
高速SPI配置寄存器2（HSSPI CFG2），其
SS_DACT：高速模式时SS控制信号的DEACTIVE 时间，详细见下图：好像也不对，没联系啊

辛苦版主帮忙看看，是否有办法设置交换MOSI和 MISO脚位？

你看的别的型号例程，32G12K128没这功能。而且8H只能交换MOSI和MISO,不能交换SCLK
