It would be useful if you could include a function for Display Test and Shutdown operations for the MAX7219 as described in the datasheet. It is similar to the brightness function but with an other address part. Please have a look at it!! ![Smile :)](./images/smilies/icon_e_smile.gif)

Re: Character Display MAX7219 features
I don't see the added value of this. If you want to test it then you can write to the display whatever you want.
Re: Character Display MAX7219 features
If you write 88888888 to test a display, then you should find the previous values to write them back, when the test is over. And writing on 3 daisy chained MAX7219 simoultaneously (6 displays) doesn't always work properly on AM.
Re: Character Display MAX7219 features
That's because we're working on an update for these displays (and more). It's not really a vital piece of hardware, so I rather invest valuable development time into something more useful.

Re: Character Display MAX7219 features
I understand, but it's not like they're build in to a real aircraft or such. There's a lot of stuff that's nice to have, but we have to choose what we put time into, then I rather put into something like navigational features.
