I have created a photo album using an ESP32 and a red 2.4" TFT 240x320 display. The images are crisp and look really good. The 2 libraries used are: #include <TFT_eSPI.h> // JPEG decoder library #include <JPEGDecoder.h> Now, I thought I’d try the same sketch on the CYD (Cheap Yellow Display (ESP32…

Hi @lexter333 , Before I reply to this thread, I'd like to see if the next thread you asked about has been resolved. [image] Displaying PNGs on ILI9341 WITHOUT LVGL Programming I’m trying to display images on an ILI9341 WITHOUT using LVGL. I am at a point whe…

Yes that has been resolved (ish). I changed the file types to .jpg and used the JPEGDecoder.h instead and the result as above works fine. No matter what I tried with the png files it kept failing. I seen a post on another site and it worked great.

Okay, that's find. I'd appreciate it if you could post the solution you found so that others can benefit. Regarding the color issue, there are two types of 2.8-inch CYDs, depending on the number of USB ports. [image] GitHub - witnessmenow/ESP32-Cheap-Yellow-Display: Building a commun…

Here is sample code using LovyanGFX for the 2.8-inch CYD. /*================================================================================ * Loading PNG / JPEG files from SD card to LCD with LovyanGFX *================================================================================*/ #include <S…

Just tried this using about 40 .jpg files on the SD card /*================================================================================ * Loading PNG / JPEG files from SD card to LCD with LovyanGFX *================================================================================*/ #include <S…

After trying all the above the images are still poor quality.

[image] lexter333: all I get is a black screen. The program I posted requires that all photos be saved in the root folder of the SD card. If you want to display photos in a subfolder, modify the program by referring to listDir() in SD_Test.ino . [image] lexter333: still poor quality. "…

I'm very sorry, but the code I posted was confirmed to work with the ILI9341, but when I checked it again with the ST7789 type, it seems that there are some models for which automatic detection does not work :sweat_smile: This time I will share code that works on an ST7789 type board: /*==========…

You are an absolute star!!! That worked perfectly. I wouldn’t have been able to work that out myself. The JPG files are crisp, just like the red ILI9341. The images in the uploads a bit look poor but that is due to my phone. They are perfect. I cannot thank you enough. I’m actually making a deskto…
