No good Buisness Idea. I think a normal Person, maybe one in a Chin Restaurand? A Person living in your City.
The count of Chips ist the same as the older one ? Or half? Bad English. How many Chip are on the Displays?
The Video is different i hoped.
The low red seems a not/bad filled memory?

The same number of LEDs. 20x40 Total 800 LEDs
30 SM16227 chips
10 MT4953A1 chips
1 74HC138B chip
2 74HC245 chips
Yes, the red lines (and the red-orange ones) are most likely not the correct memory filling.

So they had to drive more then 16 LED ( switched by oe ?)?

SAMEGO · 21. Februar 2021, 09:38

May be. But how do I make it work?

SAMEGO · 21. Februar 2021, 11:26

A few years ago, we made code for the P10 matrix.
I was redrawing the matrix diagram. Perhaps this scheme is the same in this matrix. The only difference is in the driver chip and their number

Pluto25 · 21. Februar 2021, 13:56

These Chip must drive 32 Leds too? You've the Code? Maybe it works even. I 've the Problem: no Chip here .
I can't test anything. You've the Datasheed the other Chips? (In language with ascii Symbols

SAMEGO · 21. Februar 2021, 14:49

SM16227 for 32 leds? But why? When there are only 800 LEDs on the matrix.
There is no datasheet for the old chip.

Sure

Why easy

800/30Chip = 27/chip - Wrong calkulation a_71_f9c57bbe

800*3Color /5Pages/30Chip = 16/chip :whistling:

Now i understand how it could work correct some times.
You've the Code from P10 ?

SAMEGO · 21. Februar 2021, 15:27

Possible.... chips 32 pieces. The Chinese sometimes hide them under the thick edge of the case. I'll take the case off today to make sure.

SAMEGO · 21. Februar 2021, 15:53

32 chips!
But the chips are different-FM6126B

The A2560_SSD1963.bas works with 750xP10? (Graphic 800x480)
The SSD1963_xxx.inc are missing.

SAMEGO · 21. Februar 2021, 17:24

I don't know. I don't have A2560

SAMEGO · 23. Februar 2021, 05:51

Really, do not run the matrix?

Pluto25 · 23. Februar 2021, 07:10

Let's have a look in the SSD1963_xxx.inc.
The P10 works with , maybe the 16227 "speaks" the same.

SAMEGO · 23. Februar 2021, 08:31

And how to test it?

Pluto25 · 23. Februar 2021, 15:46

In the SSD1963_xxx.inc are the Routines the P10 works with. I don't have them so i couldn't say some needfull.

SAMEGO · 23. Februar 2021, 16:10

I don't have any such matrices either. There are P4 P5 P6 P8 All RGB

The Code is lost?

SAMEGO · 23. Februar 2021, 16:27

The code in the post is 29. But it's very old

Pluto25 · 23. Februar 2021, 16:50

This Code needed the SSD1963_xxx.inc. Without it does nothing. But You do not sended its.
