[SOLVED] ILI9341 STM32 Blue pill

I apologise for this but i am new to stm32 and I’ve been trying to get the display working for 3 days now with no joy. I am obviously missing something simple. I understand there is plenty of previous posts out there on here but after reading all them through im still no further forward.

I am using the graphics test code and i’m recieving the data back through the serial port correctly so the board has programmed correctly.

My code is;

#include "SPI.h"
#include "Adafruit_GFX_AS.h"
#include "Adafruit_ILI9341_STM.h"

// For the Adafruit shield, these are the default.
#define TFT_DC PA15
#define TFT_CS PB4

// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
Adafruit_ILI9341_STM tft = Adafruit_ILI9341_STM(TFT_CS, TFT_DC);
// If using the breakout, change pins as desired
//Adafruit_ILI9341_STM tft = Adafruit_ILI9341_STM(TFT_CS, TFT_DC, TFT_MOSI, TFT_CLK, TFT_RST, TFT_MISO);

void setup() {
Serial.begin(9600);
Serial.println("ILI9341 Test!");

tft.begin();

// read diagnostics (optional but can help debug problems)
uint8_t x = tft.readcommand8(ILI9341_RDMODE);
Serial.print("Display Power Mode: 0x"); Serial.println(x, HEX);
x = tft.readcommand8(ILI9341_RDMADCTL);
Serial.print("MADCTL Mode: 0x"); Serial.println(x, HEX);
x = tft.readcommand8(ILI9341_RDPIXFMT);
Serial.print("Pixel Format: 0x"); Serial.println(x, HEX);
x = tft.readcommand8(ILI9341_RDIMGFMT);
Serial.print("Image Format: 0x"); Serial.println(x, HEX);
x = tft.readcommand8(ILI9341_RDSELFDIAG);
Serial.print("Self Diagnostic: 0x"); Serial.println(x, HEX);

Serial.println(F("Benchmark Time (microseconds)"));

Serial.print(F("Screen fill "));
Serial.println(testFillScreen());
delay(500);
