on the emails, yea i still get them. perhaps you have a junk filter that blocks it?
as for the images, as it looks now, it seems that everything on the rainbowduino as fas as custom bits, has to be progammed into an image map of r g b values. in the rainbowduino code, the data,c file, there is the variable named ‘Prefabnicatel’ which has the image maps in them.
you then call on the seeeduino
ShowImage(address, image, shift);where image is the place in the Prefabnicatel array on the rainbowduino.
im not sure if the rainbowduino is currently able to accept custom coordinates to turn on or off via the seeeduino over i2c. i dont see it in the code, the only commands are ShowImage, ShowColor, and ShowChar so you would have to implement that portion yourself.
that could be something fun to work on though.
