How to display image on TTGO-T-Display ESP32

Using Arduino Displays

I used the sample code of Jpegcoder and An error keep occur:
Arduino: 1.8.19 (Windows 10), Board: "LilyGo T-Display, Disabled, Core 1, Core 1, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 921600, None, Disabled"

Sketch uses 353105 bytes (26%) of program storage space. Maximum is 1310720 bytes.

Global variables use 24488 bytes (7%) of dynamic memory, leaving 303192 bytes for local variables. Maximum is 327680 bytes.

usage: esptool [-h]

I had the same error. There were two lines missing in .arduino15/packages/esp32/hardware/esp32/2.0.14/boards.txt:

lilygo_t_display.upload.flags=
lilygo_t_display.upload.extra_flags=

Lines added, IDE restarted, uploading worked...

Is it a TTGO T-Display S3?

when yes, go to their GITHUB:
GitHub - Xinyuan-LilyGO/T-Display-S3

download and install the

TFT_eSPI

start with the Sketch

T-Display-S3/example/tft at main · Xinyuan-LilyGO/T-Display-S3 · GitHub

should work right of the box. Includes an example to display an image.

I cant upload an image, when I check the serial terminal, it appear this error:
E (599) esp_littlefs: ./components/esp_littlefs/src/littlefs/lfs.c:1347:error: Corrupted dir pair at {0x0, 0x1}

E (599) esp_littlefs: mount failed, (-84)
E (600) esp_littlefs: Failed to initialize LittleFS
SPIFFS initialisation failed!

This resolved uploads for me using the T-Display template. Previously I was just using ESP32 Dev Board without issue, but had to manually set everything.

You just made my day, thanks!

you're a lifesaver! this worked
