* 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
|
||||
* Pico: https://github.com/earlephilhower/arduino-pico-littlefs-plugin.git
|
||||
* SPIFFS (ESP32):
|
||||
* upload SPIFFS data with ESP32 Sketch Data Upload:
|
||||
* ESP32: https://github.com/lorol/arduino-esp32fs-plugin
|
||||
* SD:
|
||||
* Most Arduino system built-in support SD file system.
|
||||
* Wio Terminal require extra dependant Libraries:
|
||||
* - Seeed_Arduino_FS: https://github.com/Seeed-Studio/Seeed_Arduino_FS.git
