Change od Text Clour for just text plugin #43

Closed franki29 closed 3 years ago

franki29 commented 3 years ago

Hi, first of all a great software. Maybe I too stupid to find, but is there any way to change the color of the text when I am using the just text plugin?

Thanks for helping

Hi Frank, you can change the text color by using the text prefix \#RRGGBBYourText The single backslash forces the software to try to interpret the following characters. Note, for changing the color via sourcecode you must have two backslashes in the string. One additional for escaping. The '#' is the begin of a color, RR = Red value in hex GG = Green value in hex BB = Blue value in hex

Example: \#ff0000Hi!" image

The description is currently only in the sourcecode: https://github.com/BlueAndi/esp-rgb-led-matrix/blob/4b2b2ac22e40b4ee8b41ee60c1725e4f5634e41a/lib/Gfx/TextWidget.h#L60-L73

Hi, thanks for your information, but it does not work at my side. I am using node red to send text to the display. As soon I add \#ff0000 to the message, it will display nothing.

Same for: curl -X POST http://192.168.2.95/rest/api/v1/display/uid/19652/text?show=\\#FF0000Testgadsghdasghdsaghdsaghadsghdsaghsadgh Return is: { "data": {}, "status": 0 Sure I am doing something wrong, but what?

Please be aware that you have to replace unsafe ASCCII characters by the respective percent encoding within your url Try to use %5C instead of \ and %23 instead of #.

Hallo Frank,

Kannst Du Deine Node Red Nodes teilen - ich bin auch gerade dabei und hab viele Fragezeichen

Hallo Christian, bin leider kein Experte daher sieht mein Node ziemlich wild aus, da ich von meinem Internetradio die Infos abhole und dann an das Display schicke. Einige Sonderzeichen wie & oder ' sowie () habe ich bisher nicht hinbekommen. Das eigentliche senden der Infos geht aber.

Ich nutze den http request note zum senden:

[{"id":"a3afeaa6.25db9","type":"http request","z":"d31b6ff4.b783c","name":"","method":"POST","ret":"txt","paytoqs":"ignore","url":"http://192.168.2.95/rest/api/v1/display/uid/19652/text?show={{payload}}","tls":"","persist":false,"proxy":"","authType":"basic","x":1450,"y":1340,"wires":[[]]}]

Dazu sende ich den Payload als String.

Was ist denn die Quelle der Daten?

Anbei ein node zum senden von Daten eines MQTT Servers an das Display:

Danke - hilft mir bestimmt Ich bin noch am Konfigurieren Teste Übertragen etc und versuche den aktuellen Slot auszulesen . Ist bei dir im Web Interface etwas einstellbar ? bei mir geht nur bei installiertem Plugin das ändern der Texte oder Symbole.

franki29 commented 3 years ago

So weit ich das mitbekommen habe, muss man den Slot erst im Web konfigurieren und dann sieht man auch die UID. Aber laut der Dokumentation https://github.com/BlueAndi/esp-rgb-led-matrix/blob/master/doc/WEBSOCKET.md kann man die Slots auslesen. Habe ich aber nie benutzt.
