ST7789 Temp Display

Hello,

Im trying to find a way to make a temperature gauge using a st7789 display with arduino and not have the temperature update without flickering. Is this possible?
Using Arduino MEGA 2560
2inch LCD Module ST7789
This is the code i have so far
#include <Adafruit_GFX.h> // Core graphics library
#include <Adafruit_ST7789.h> // Hardware-specific library for ST7789
#include <SPI.h>

#define TFT_CS 53
#define TFT_RST 9
#define TFT_DC 8

Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_RST);

#define TFT_MOSI 52 // Data out
#define TFT_SCLK 51 // Clock out
int ThermistorPin = 0;
int Vo;
float R1 = 10000;
float logR2, R2, T,T1;
float c1 = 1.009249522e-03, c2 = 2.378405444e-04, c3 = 2.019202697e-07;

void setup(void) {
Serial.begin(9600);
Serial.print(F("Hello! ST77xx TFT Test"));

tft.init(240, 320);           // Init ST7789 320x240  

tft.setTextWrap(false);
tft.setRotation(3);
tft.setTextSize(5);
tft.fillScreen(ST77XX_BLACK);
}

void loop() {

Vo = analogRead(ThermistorPin);
R2 = R1 * (1023.0 / (float)Vo - 1.0);
logR2 = log(R2);
T = (1.0 / (c1 + c2logR2 + c3logR2logR2logR2));
T = T - 273.15;
T1 = (T * 9.0)/ 5.0 + 32.0;
tft.setCursor(0, 30);
tft.setTextColor(ST77XX_RED);
tft.println(T1);
delay(10000);
tft.setCursor(0, 30);
tft.setTextColor(ST77XX_BLACK);
tft.println(T1);
}

Remember the previous value and only perform the display (print old value with background color then print new value in foreground color) if the value has changed.

Please use codetags. (please read How to get the best out of this forum and modify your post accordingly.)
