Hello Bodmer!

Thank you SO MUCH for all your work on this stuff. My project is going to ROCK because of you.

Can you or anyone tell me why I'm getting these artifacts when I try to display JPG images with your libraries?

Here's my code (based on your NodeMCU_Jpeg example sketch):

#define FS_NO_GLOBALS
#define TFT_BLACK 0
#include <FS.h>
#include <JPEGDecoder.h>
#include <SPI.h>
#include <Adafruit_GFX.h>
#include <TFT_eSPI.h>
TFT_eSPI tft = TFT_eSPI();

void setup()
{
  Serial.begin(9600); // Used for messages and the C array generator
  delay(10);
  Serial.println("NodeMCU decoder test!");
  tft.begin();
  tft.setRotation(0);  // 0 & 2 Portrait. 1 & 3 landscape
  tft.fillScreen(TFT_BLACK);
  if (!SPIFFS.begin()) {
    Serial.println("SPIFFS initialisation failed!");
    while (1) yield(); // Stay here twiddling thumbs waiting
  }
  Serial.println("\r\nInitialization done.");
  listFiles(); // Lists the files so you can see what is in the SPIFFS
}

void loop()
{
  tft.setRotation(0);  // portrait
  
  // Display Gear Image
  tft.fillScreen(TFT_BLACK);
  drawJpeg("/t5_gear.jpg", 0, 0);
  delay(2000);

  //Display Water Day image
  tft.fillScreen(TFT_BLACK);
  drawJpeg("/waterday.jpg", 0, 0);
  delay(2000);
}

I have attached both of the original 240x320 JPG image files to this message...maybe there's something wrong with how they are encoded? I cannot figure this out.

Thank you so much for your help!
