LED Display

[koolguy]

Hello,
How to use P10 led display for custom application for custom purposes in projects.
ay idea??

On Ebay... Mad electronics sell a controller card that will support 40k pixels..

Hi.
I dont have data sheet here is info of it:
1. 16x64 Red color midule work with cards like BX5m1 / bx5ul/bx5ut
here is in post #2 similarhttp://forum.arduino.cc/index.php?topic=260320.0

The last link includes an arduino library!!

Can't get any easier than that..

 

[koolguy]

No i was showing p10 pin connection!

There is LED SHOW software for using it..
What does Scanning mode mean 1/16 1/8?

 

[Ian Rogers]

Duty cycle.... Percent off / percent on... It comes from the scan lines.. Lets say you have an 8x8 matrix..
Only one row will be active in any one time frame, so there will be 8 time frames. Therefore the LED's will be on a 1/8 duty cycle... 1/16 will have 16 scan rows.... The higher the duty cycle the dimmer the LED's...

Hello,
Can we go with PIC with this module?
and What does this mean https://i351.photobucket.com/albums/q452/plclark3/MatrixCable.jpg

 

[Ian Rogers]

Mean?? Its a connector with SPI functionality... Its so you can link in the modules...

 

[koolguy]

Hello,
Yes the Module are link series with other and there is limit depends on cards

 

[koolguy]

So, You want to say is it SPI?

 

[Ian Rogers]

Looks like SPI..... To far really for I2C... It looks like there is two types... SCLK and CLK may be for two protocols

You have a DATA line and oodles of what seem to be Chip Selects...


I have run through the code.. It is SPI and works exactly the same as my examples I did for you previously!!

 

[koolguy]

So, We can use it with PIC Microcontroller ?

 

[Ian Rogers]

You can! The matrix in the link you posted has 512 pixels That is 16 x 32... The one I did for you was also 16 x 32

 

[koolguy]

Duty cycle.... Percent off / percent on... It comes from the scan lines.. Lets say you have an 8x8 matrix..
Only one row will be active in any one time frame, so there will be 8 time frames. Therefore the LED's will be on a 1/8 duty cycle... 1/16 will have 16 scan rows.... The higher the duty cycle the dimmer the LED's...

But I can't understand what is the reason that in display we test that was 1/8 scan,right?
was giving less bright than other and this p10 use 1/4 scan there is no flicker and seems bright does it depends on Processor Too?

 

[Ian Rogers]

1/4 scan is far better than 1/8... Its 25% vs 12.5% on time...

 

[koolguy]

There is no fluctuation in 1/4 scan gow these display are working inside?in that we made was fluctuating in column scan, why?
here is p10 display pins:
0 a
n b
n c
n s
n l
n r1
n g1
n d

Hello,
Here i found the panel of P10 looks similar to shift register .

Hello,
How draw Pattern on led's?
Is there any software or something to show effects...?
