NEED HELP

So I ma doing a project where I need to interface an TFT LCD 240*240 ISP ST7789 with C8051f120 microcontroller using SPI interface I have written the program but I am not getting Output on LCD would appreciate if anybody will help :) here's my code do let me know if there's any problem with code. P.S I have initialized the port and mcu parameters in c8051f120.h

#include <c8051f120.h>
#include <tft.h>
#include <stdio.h>
#include <stdlib.h>
#include <intrins.h>
sbit SPI_SCLK=P2^1;     
sbit SPI_MISO=P2^3;     
sbit SPI_MOSI=P2^2;     

void main()
{
	
	SFRPAGE = SPI0_PAGE;
	
	delayms(100);
	ST7789V_Initial();
	delayms(100);
	SPI0CN = 0xF8;
	Draw_Circle();
	
  
	BACK_COLOR=WHITE;
	POINT_COLOR=RED;
	
	delayms(140);
	
	
	
}
void Draw_Circle(unsigned int x0,unsigned int y0,unsigned char r,unsigned int color)
{
	int a,b;
	a=0;b=r;	  
	while(a<=b)
	{
		LCD_DrawPoint(x0-b,y0-a,color);             //3           
		LCD_DrawPoint(x0+b,y0-a,color);             //0           
		LCD_DrawPoint(x0-a,y0+b,color);             //1                
		LCD_DrawPoint(x0-a,y0-b,color);             //2             
		LCD_DrawPoint(x0+b,y0+a,color);             //4               
		LCD_DrawPoint(x0+a,y0-b,color);             //5
		LCD_DrawPoint(x0+a,y0+b,color);             //6 
		LCD_DrawPoint(x0-b,y0+a,color);             //7
		a++;
		if((a*a+b*b)>(r*r))
		{
			b--;
		}
	}
}
