[完结撒花]移植ST7789V代码从单片机到Cortex-M4 LCD出现雪花屏

五一调试了以前买的LCD屏淘宝链接
商家给的资料只有51的我用51测试可以正常显示于是乎我想移植到HC32F460(Cortex-M4)中不过调试了2天半只是得到了个雪花屏的结果。
由于手上没有合适的拍摄工具只能给张差不多的图片

而且这是在初始化阶段就会出现的而不是调用显示字符函数时出现的,我初始化的参数全是照着51代码写的不知道是不是对齐的问题
后天就要去学校了在此把代码发出，不要求各位大佬给出完整解决方案,给个思路就行用以帮助我在下周的调试。希望能得到大家的回复。
我把代码和商家给的资料放在百度网盘了就不站论坛的空间了

还有初始化单片机代码贴在下面

#include "lcd_init.h"

stcPortInit.enExInt = Enable;
stcPortInit.enPullUp = Enable;
// PORT_Init(LCD_PIN_PORT , LCD_BLK_PIN | LCD_RST_PIN | LCD_DC_PIN | LCD_SCLK_PIN | LCD_MOSI_PIN

PORT_Unlock();
M4_PORT->PSPCR = 0x0Bu;
PORT_Lock();
