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

I am using some P16 Drive Board Version 4.0 RGB LED MATRIX PANNEL Module for custom Display of Text... I donot know how to display custom text ,, i watch tutorial on youtube they have P10 led module and there is Library name RGB matrix pannel but this library and the pins in the library is not matching with mine one ,, i dont know which library i will use for it... ANY one Wantns to Help


there are several wires connected to input. where are those connected to other side?

Ignore the connection of Pins at Input which i done....Just check the Pins they have 16 pins 5 pins are GND , R1 ,R2 , G1 , B1 , R3 , R4 , G2 , B2 , SCK , STB , OE i have no idea how to connect them with Arduino and display custom Text...Which library i will use in Arduino Ide earlier i try RGB Matrix Pannel Library but it was for the P10 Led moudle ... not for this one as well as Pins were also change from each other....Simple i want to display text how can I

I google search every where but did not find something related to this... If some one find something really helpful share it here

i have found a user manual for it. And it says you need a receiver card (page-2 of pdf)
Specification of the control system (fccid.io)

can you share what is written on those ICs?

Do you use Whatsaap ? I will share a Voice message

I have attached the Picture above

74Hc2450

the picture above isnt clear enough. i cant see the part no. on IC

sorry, but we don't share personal contacts here.

there are two types of ICs. Post a clear picture so the part number is clearly visible

or more

Most RGB panels has a three type of IC - led driver, line driver and a buffer.
The specified 74HC245 chip is a buffer, the least important of all :slight_smile:

Perhaps the pins R3 and R4 corresponds to A & B on P10 RGB panels.
With this assumption, all pins fully comply with the HUB75 standard of modern RGB matrices, so you could try to run the panel with RGBMatrixPanel library.

But P10 have C D pins along with A B so the RGB matrix pannel library have code for the A b c d pins so what can i do next , should i remove the C d from code or from the matrix library ?

Here in pic i write the pins then as you mention Hub75 pins configuration then let me know about this pins what it called as you mention Hub75 then it will be Hub76? Or some.other name ? And also let me know the libray arduino library for.this config as in pic arduino have RGB matrix pannel library for Hub75 config P10 !! but i donot know they have library for the Pic o have attached p16 ? Let me know.or give me clue how can i connect this with arduino for text display

P10 and P16 (and also P3, P6 and so on) - not more than a pitch between pixels in mm. "P10" say nothing about the matrix type and its protocol.

I have been working with LED matrices for 7 years and have seen a lot of different matrices.
Your panel looks quite old and non-standard. Most likely you will not find a library designed specifically for such a panel. If you want to run it, then you have no choice but to experiment with different libraries and pin connections. I offered you a connection option, but I do not guarantee that it will work. This can only be established by experience.

If you don’t want to experiment, and just want to display text on the screen, I think it’s easier for you to buy a modern panel.

Addition
I found the pinout of your panel in the internet. Such type is called as "HUB40" .

If you have some experience how to run then please do share your experience as i try different methods for two days...donot know how to do it...thats why i post on forum...

just two days... you are at the very beginning of your journey.

You didn't answer my question - do you want to solve a problem with this panel as a practice in programming and electronics or do you just need a matrix for text?

I asking because reverse engineering the protocol of this panel is not such an easy task and requires knowledge of electronics and programming. What is your experience with this?

I have some experience, but not with your panel. So this will be a something like a challenge.

Also - how do you going to use it in case of success?
Do you realised that matrices with DIP LEDs with such big pitch - 16mm - designed for using in huge screens viewing from a distance of 10-15m.
What is the matrix dimensions in pixels? How many panels do you have?
