Hi,
beutiful project, i'm using it at home.
I tried to "upgrade" by adding another 2 max7219, so to have 4 max7219 but only and set:
#define MAX_DEVICES 16

but only first 8 display works.
do u have an idea?
thank you

I also tried to power the 4 4max7219 with an external powersupply, is not a current problem.. seems it could not drive more than n8 fc16 (2x max7219)

In the meantime I will try do change the sketch to drive with other different output of the wemos another 2x max7219, and different topic

Hi,
Did you change zones config to use all your 16 segments? https://github.com/widapro/pixel_led_mqtt_panel#optional

I guess you should have something like that:

  P.begin(2);
  P.setZone(0, 0, 14);
  P.setZone(1, 15, 15);

Thank you! Was that! I have to use an external power supply anyway cause the wemos can’t drive the chain
