P16 RGB Led Matrix connecting with Arduino Uno for custom Text display

Other Hardware LEDs and Multiplexing
21

I just want to display text , I am beginner

22

I think it would be better for you to buy another panel.

23

Why not this one ?

24

I have this pannel then what shoukd i do with this one !

25

Ok, could you answer my two last questions at the end of post #20?

26

Ok , i cannot do this stuff as i am not familiar with this...Thanks for your help i qppreciate...i need to buy new one

27

I asked you about panel dimensions in pixels. Is it so difficult to answer?

28

16*32

29

Try to connect panel to arduino, using library RGBMatrixPanel .
Pins R1 G1 B1 R2 G2 B2 to R0-B1 in the library, R3 and R4 to A & B.
SCK - to CLK
STB to LAT
OE to OE

Use settings to 32x16 matrix

Most likely, the panel will not show text or pictures - but at the first stage I wonder if there will be anything on it.

30

I tried this one...

31

And what was the result?

32

Nothing at output

33

There can be two options here - either you connected something wrong, or the matrix is ​​incompatible with this library

I have no other ideas how to help

34

I think this library is uncomfortable bcz whe i checked the Cpp file it have built in function for the P10 module...I try to remove and then check what if work but nothing at output

what is written on these ICs?

if it is similar to ICs used in hub12 interface you could use it with slight changes in codes

36

Big one are 74HC245 and the small one writting is too small not clear to see

37
  • i think the smaller one is 16bit shift registers like- STP16C596. but it would be better if you could confirm the exact part no.
  • Are the smaller one 32 in total?
  • Is there any other IC than those two?
  • Can you post pic of whole board?

:slight_smile: quote="ah_1233, post:34, topic:1280140"]
it have built in function for the P10 module
[/quote]

What does it mean?:slight_smile:
p10 is a format for arranging LEDs on a panel, the function in the library cannot be "built for p10", it is non-sense

39

The shift register needs a three address lines, while in the panel we can see a two only.
Also, in case of SR we would see something on panel...

pin 5 to 20 is connected to Leds and pin 23 has ext-resistor which makes me think of sr STP16C596
