Hello guys, after having worked fine, Awtrix suddenly only shows the top part of the screen.
is the matrix broken or is this a controller firmware problem ? I checked all solder joints and the seemedfine!
Ok now very strange behaviour. Sonetimes full screen starts working then suddenly lower part seems to be hanging and maintains prior content
anyone with ideas ?
This looks like a broken matrix. One LED seems to be dissolder, therefore this one led doesnt forward the signals to the nex ones
But it is really divided in half so upper 4 collums work while lower ones dont
this behavior starts like 30s-1m after awtrix is plugged in
yeah. the leds are arragend in columns. So if the right LED of the 4th columnis broken or the first in the 5t,h the signal cant reach the next ones. The controller isnt able to only display a half of the screen, full or nothing, even with a software fault. If you say the lower 4 column freeze then there is no further signal and the LEDs do nothing but shows the last data information.
Your Matrix should be arranged like this:
