Espeasy: Max7219 led matrix

[Rixtyan]

Hi. I'm just try to make clock with max dot matrix display. But occasionally espeasy doesn't support it, however 7dot display module try to show something.

Besides i can't build any firmware, every time i dont have a lot of plugins, so i even cant try to do it.

So i ask: if somebody got this plugin - pls share it, maybe we could finally move it to production.

Max7219 is supported by the Display - 7-segment display plugin, that's included in the normal and test builds (for at least 2 years), and supports to display as a clock in either 12h or 24h format, so I'm not sure what your request actually is...
Have you tried a recent build of ESPEasy (download from here)?

So the request is to add support for the dot matrix display. Valid request.

Aha, 'great' to have 2 different hardware items use the same type# 😠

Or expand the plugin.

I've ordered such Max7219 matrix display, so I'll have a look at it once it arrives (ordered from Aliexpress so may take a few weeks).

I've tried to code some plugin, as source i used p073 plugin. It works with max7219 and even dot displays, but only as test. Actually problem is using more than 1 display (vertical/horisontal).

I'm trying to code something, but its a little bit complicated, code, i've been copied from GyverString for example, needs to be updated for espeasy. And my c++ skill (one week after work) needs time for this)

I am running into an config problem.
I have a wemos D1 mini with a MAX7219 connected. 1st GPIO D7, 2nd GPIO D5, 3rd GPIO D4.
Used various builds (normal, test, display) from 20201227 but no luck in displaying anything readable. All 4 digits show the same strange code.
What am I doing wrong?
Let me know.

EDIT: I see that it needs a 8 digit MAX7218, not 4.

We don't have support for the dot matrix yet. So your max7219 is turning on what it believe is a 7-segment LED.

You need to wait for it to be released.

That makes sense. I see now they are not the same.
Thanks.
