* PNG Image Viewer
|
|
* This is a simple PNG image viewer example
|
|
* Image Source: https://github.com/logos
|
|
*
|
|
* Dependent libraries:
|
|
* PNGdec: https://github.com/bitbank2/PNGdec.git
|
|
*
|
|
* Setup steps:
|
|
* 1. Change your LCD parameters in Arduino_GFX setting
|
|
* 2. Upload PNG file
|
|
* FFat (ESP32):
|
|
* upload FFat (FatFS) data with ESP32 Sketch Data Upload:
|
|
* ESP32: https://github.com/lorol/arduino-esp32fs-plugin
|
|
* LittleFS (ESP32 / ESP8266 / Pico):
|
|
* upload LittleFS data with ESP8266 LittleFS Data Upload:
|
|
* ESP32: https://github.com/lorol/arduino-esp32fs-plugin
|
|
* ESP8266: https://github.com/earlephilhower/arduino-esp8266littlefs-plugin
