I am writing a program that gets an image encoded in base64 through the Serial port. I want to then load that image in my Processing program to analyze it. It seems that loadImage() should work with base64 encoded data, provided you use the right header ( reference ), but even the gist used in the pu…

Hello @papertree , If this sends the terminating character it needs to be trimmed on receiving end: https://docs.arduino.cc/language-reference/en/functions/communication/serial/println/ Reference: trim() / Reference / Processing.org Example: [image] Try while (myPort.available() > 0) in your …

Hello @papertree , Welcome to the forum. Assuming the system silenced you automatically for enthusiasm and you will be back soon! I simplified your code without the serial and this works on my end: import java.awt.Image; import java.awt.Toolkit; import java.util.Base64; import java.io.*; import j…

I since discovered that, since I changed the code that took and encoded the images, the base64 strings I was receiving through the Seria…

@sableraph Thanks! Really appreciate it.

Hi @glv , I had no idea the Arduino serial.println() method printed a \r at the end of the data. Thanks for your trim() suggestion inside or Processing, everything works as expected now! I haven’t encountered the Illegal base64 character d again, either, so that was the issue there also. Thanks a …
