<![CDATA[drawing a base64 encoded image on M5Stack Core]]>Greetings,
Do you have a minimal example in Arduino/C showing how to draw a base64 encoded image? Imagine I have an image that is saved as a base64 string (either in a string variable or in a text file, doesn't matter). The question why I have the image as base64 encoded string is out of scope :). How do I draw this image on the screen of an M5Stack Core? Thanks in advance!

Note that I am not talking about encoding an image to base64, nor about serving (webpages containing) base64 images. I have a base64 encoded image saved on the M5Stack Core and I want to display it on the screen.

The tutorial is about strings, but works in exactly the same way for base64-encoded jpg images. All you have to do after decoding the string (containing the base64-encoded jpg image) is to write it to SPIFFS and then call M5.Lcd.drawJpgFile(SPIFFS, jpgFileName, 0, 0);
