LED Matrix MQTT Sign

I would say that you don’t have the correct libraries installed, the latest Max72xx and MD_Parola should be installed.I have 3.0.2 for Max72xx and the same for MD_Parola.

Hi @vbh

How is the matrix sign working for you? I have just ordered the parts and will be using your latest code that you shared the link of to build mine.

Anything I need to do before uploading it to my esp8266?

Thanks.

Hi @keithh666

Is it possible to have another effect instead of scrolling text? I have checked the parola library and they have many effects which we could use.

Trouble is I do not know how to code and integrate it the way you have done.

Can you advice or guide me please?

Thanks.

122

Still running strong! Make sure to use correct lib versions, the code is solid but in my experience it will always need some tinkering to get it running (but without this it would be less fun and rewarding) :wink:

123

Other effects are possible, i removed them but they can be added back without too much hassle. You can make them controllable by mqtt which would be cool. The reason i removed the effects is because after testing them i found them all to be less effective in actual use compared to just scrolling.

124

Oh can you share the code that you used with the effects please?

125

Did you post the code which contained different effects? I haven’t seen it

hello - i have problem : can you help… the serial monitor sayd:

wdt reset
load 0x4010f000, len 1384, room 16
tail 8
chksum 0x2d
csum 0x2d
v8b899c12
~ld

127

That’s a WatchDog Timer reset so something is taking over 8 seceonds to complete without letting the wdt update. You will have to say which version of the code you are using (however removing the ota code may stop the problem if you are using it).

Would you mind explaining how you have your google calendar garbage pickup functions set up? Do you have specific wording/times set up for each calendar?

I just created 2 new calendars: garbageblue (recycling) and garbageblack (trash), with all day events set up for alternating thursdays (blue is every second thurs, and black is every other second thurs). But I do not have a strong grasp of understanding function nodes to get this to work properly.

Also, would you mind providing an example of code to throw in there if you wanted to attach a lux sensor right to the device (using a pin the D1 mini) so that it can control the brightness based off of its own sensor? This feature does not seem to work when I use one of my bruh multisensor lux sensors as the entity.

Thanks for posting all of your setup so far, it is working well for me.

thanks i think it was the libraries version …

Hi friends can someone post a complete zip with libraries and sketch that works i have tried all and cant get it to work. I have a lolin node mcu V3. And a FC16 module and it wont bust in serial monitor i get a sam wdt restart error like someone before me. This is a project i have left to long on wait. If anyone is kind enough to push the code somewhere with some helpfull insctructions many thanks.

131

Here is the latest code tho’ I couldn’t include the PubSubClient so you will have to do that via manage libs- you will need version 2.7.

Also the code won’t work with the latest Arduino IDE (ver 1.8.10) due to a libraries conflict, it does work with 1.8.9 :).

Hi Mate… Would you mind sharing the config agiain. I am lost in this Threat here :stuck_out_tongue: how would I send sich a mqtt message?

Something like the following…

Thanks… but didn’t get the stuff runing yet… it compiles … connects … but sending a message via mqtt in hass wont show any message on the sign itself. Did u change the wiring?
I think i will have to double check the wiring given in the code.

135

Mines always used D5,6 and 7 on a D1 Mini

#define CLK_PIN D7
#define DATA_PIN D6
#define CS_PIN D5

136

I just checked the code and indeed i had another wiring… Let me setup hassio and all the stuff (simply from backup) and revert to you. But seems good so far… serial monoitor shows connecting to wifi . My hassio crashed yesterday after having upgraded something … but as I made it in a bunch of actions … I dunno what causes this issue… my homeassistant runs… but webinterface and most of autmations don’t … don’t ask! :slight_smile: But I will tell you for the Matrix sign.

anyway … did u follow the esphome issue to support this LED matrix? did they plan to add it to esphome?

@keithh666 Just a stupid question: #define MAX_DEVICES 12 means the amount of LED panels. Means in this cae 3 banks 4 panels each?

137

yep #define MAX_DEVICES 12 - means 3x4 panels

I have no idea about ESPHome as I’ve not used it so far.

138

got it running! mega!! could you just post all configs with input_numbers for speed etc? Then i will make a new writeup wit all informations inside :slight_smile:
