128*64 outdoor panel #1500

Help connect the panel, does not respond to the connection. I've already tried all the options. Direct connection and through bonnet HAT do not give a result. photo_5325557669932680530_y photo_5325557669932680529_y

What are the part numbers for the row driver chip and column driver chip?

davemaster commented 1 year ago

Greetings,

You have the HUB75 connections in the picture here.... check the connections again, THEN, check the power supply, this panel has a lot of RGB LEDS, try with a 20A or greater power supply, and only ONE PANEL... then try ALL THE options --led-multiplexing: --led-multiplexing=<0..17> : Mux type: 0=direct; 1=Stripe; 2=Checkered...

best regards

The DI marked pin on HUB75 is very suspicious. I doubt this panel will work without feeding some data into it. Try reading part numbers on chips. And take look at https://github.com/hzeller/rpi-rgb-led-matrix/blob/dfc27c15c224a92496034a39512a274744879e86/lib/framebuffer.cc#L121, this one at least mentions DIN pin.

IMO, at minimum, you need to connect DI pin to E signal (jumper on adapter)

photo_5330512305550639807_y I tried various options, and could not achieve the glow of the LEDs.

wata-net commented 1 year ago

The reason the LED panel does not light up may be due to the use of column driver ICs containing SRAM such as ICND2153 and MBI5153 which require a special initialization sequence. This library doesn't seem to support such driver ICs. Unfortunately, it may not solve the problem, but if you tell me the marks on the surface of the column driver IC and row driver IC, I think I can find the cause. As an aside, I feel that there is a high possibility that a slightly expensive LED panel with a pixel pitch of 3mm or less and a pixel count of 64x64 or more uses a special column driver IC equipped with SRAM. Especially when the pixel pitch is 2mm or less, the possibility is quite high. ICND2153_1

--led-panel-type= : Needed to initialize special panels. Supported: 'FM6126A', 'FM6127'

--led-panel-type Chipset of the panel. In particular if it doesn't light up at all, you might need to play with this option because it indicates that the panel requires a particular initialization sequence.

@OkSingra did you solve the problem with this panel?

OkSingra commented 1 year ago

photo_5384525951704090102_y photo_5384525951704090101_y So far I have only been able to achieve this. sudo ./text-scroller -f ../fonts/9x18.bdf --led-gpio-mapping=adafruit-hat --led-rows=64 --led-cols=128 --led-slowdown-gpio=5 "Hello World ♥"

Tadont commented 1 year ago

@OkSingra I have a similar panel and a similar hat. I can't display anything
