help, it's driving me nut, trying to solve this problem for a few days, but still no luck. tried to reinstall arduino IDE for few times already, deleted all arduino folders, libraries, and downloaded only those that are necessary im getting error for multiple libraries, but i KNOW that i have only 1 of it, cuz i deleted everything.

Arduino: 1.8.10 (Windows 10), Board: "Arduino Nano, ATmega328P"

and the funny part is, when i use some example from SPI.h it works flawlessly, but in this or any other code it doesn't. and this is code

#include <Adafruit_GFX.h>    // Core graphics library
#include <Adafruit_ST7735.h> // Hardware-specific library
#include <SPI.h>
 
#define TFT_CS     9         // TFT CS pin is connected to arduino pin 9
#define TFT_DC     10        // TFT DC pin is connected to arduino pin 10
 
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS,  TFT_DC);
 
float p = 3.1415926;
 
void setup(void) {
  tft.initR(INITR_BLACKTAB);   // initialize a ST7735S chip, black tab
 
  uint16_t time = millis();
  tft.fillScreen(ST7735_BLACK);
  time = millis() - time;
  
  delay(500);
 
  // large block of text
  tft.fillScreen(ST7735_BLACK);
  testdrawtext(" frewrherherher ", ST7735_WHITE);
  delay(1000);
 
  // tft print function!
  tftPrintTest();
  delay(4000);
 
  // a single pixel
  tft.drawPixel(tft.width()/2, tft.height()/2, ST7735_GREEN);
  delay(500);
 
  // line draw test
  testlines(ST7735_YELLOW);
  delay(500);
 
  // optimized lines
  testfastlines(ST7735_RED, ST7735_BLUE);
  delay(500);
 
  testdrawrects(ST7735_GREEN);
  delay(500);
 
  testfillrects(ST7735_YELLOW, ST7735_MAGENTA);
  delay(500);
 
  tft.fillScreen(ST7735_BLACK);
  testfillcircles(10, ST7735_BLUE);
  testdrawcircles(10, ST7735_WHITE);
  delay(500);
 
  testroundrects();
  delay(500);
 
  testtriangles();
  delay(500);
 
  mediabuttons();
  delay(500);
 
  delay(1000);
}

Ignore the "multiple libraries" remark. Your program has a bunch of errors.

First the object tft will work with the following changes:

#define TFT_RST    8         // TFT RST pin is connected to arduino pin 8

Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS,  TFT_DC, TFT_RST);

After that you will see a couple of undefined functions - that's yours.
