Sorry this time i tried to sort the 30 Codes.
The images 46-47 are made by code from #197 ?

Yes!
Already best of all!!
Some pixels flicker

I hope it was my last Copy and Paste error

SUPER!!!

I just corrected the blue color
Shift6out Memory_red(index_1) , Memory_green(index_1) , Memory_blue(index_1) , Memory_red(index_2) , Memory_green(index_2) , Memory_blue(index_1)

I will try to make other fonts and scrolling now

Copy & Paste a_67_e210de67

Whitch Sofware you use to create Images like image 46_2_true (#193)
Please show some scrolling and other fonts
What happend you overload? (to much letters or to big font)

Video Test
Works very well!
Sometimes at maximum brightness, there are flashes of LEDs. But it is rare.

SAMEGO · Feb 18th 2020, 10:04pm

Guys, many thanks! You are super!

Thanks, nice too be helpfull. a_58_b54cfdb4

Schön das wir helfen konnten.

And again hi!
Let 's connect 3 matrices vertically.
The code does not want to output to 3 matrices.

Old matrices with the correct picture
3-GKGD_001.jpg

New matrices and new code.
3-GKGD_002.jpg 3-GKGD_003.jpg
There are some thoughts?

Pluto25 · Feb 19th 2020, 5:20pm

Hi
There must be a Pin what selects the Panel ? (Enable or ChipSelect) The OE is only to shut off?
Please show shematic / Circuit

You work with differend ' Set_text_6_8 ' . Isn't it bedder to give it differend names?
Maybe Set_text_6_8v /Set_text_6_8h

SAMEGO · Feb 19th 2020, 7:32pm

The font is fine. This is a special font that outputs text vertically on the matrix.
Connection of matrixes consecutive

Lets have a look to this resulds

Source Code

' For R_0 = 1 To Dy_num_vertik
Index_1 = Page_counter * 5
Atemp = 0
For D_1 = 1 To 30
Index_2 = Index_1 + 50
If D_1.0 = 1 Then
Shift6out Memory_red(index_1) , Memory_green(index_1) , Memory_blue(index_1) , Memory_red(index_2) , Memory_green(index_2) , Memory_blue(index_2)
Else
Shift6lout Memory_red(index_1) , Memory_green(index_1) , Memory_blue(index_1) , Memory_red(index_2) , Memory_green(index_2) , Memory_blue(index_2)
End If
If Atemp = 0 Then
Index_1 = Index_1 + 25
Incr Atemp
Else
Index_1 = Index_1 - 24
Atemp = 0
End If
Next D_1
' Next R_0

Are they always standig in row or could it be that they are lying in row (other code neede)

Realy? Is G1 on Panel top the same as G1 bottom? Elektrical same ( R=0 Ohm) no shift registers?
So there must be an CS Pin. What exactly does Lat and OE?

I drew the Qjang Li matrix diagram

GKGD matrices have a slightly different scheme, but the principle is the same

It could work :

Source Code

Display_refresh:
Load Timer2 , Timer2reload
If Page_counter < 4 Then
Incr Page_counter
Else
Page_counter = 0
End If
For R_0 = 1 To Dy_num_vertik
Atemp = R_0 - 1
Atemp = Atemp * 100
Index_1 = Page_counter * 5
Index_1 = Index_1 + Atemp
Atemp = 0
For D_1 = 1 To Num_matr '10
Index_2 = Index_1 + 50
If D_1.0 = 1 Then
Shift6out Memory_red(index_1) , Memory_green(index_1) , Memory_blue(index_1) , Memory_red(index_2) , Memory_green(index_2) , Memory_blue(index_2)
Else
Shift6lout Memory_red(index_1) , Memory_green(index_1) , Memory_blue(index_1) , Memory_red(index_2) , Memory_green(index_2) , Memory_blue(index_2)
End If
If Atemp = 0 Then
Index_1 = Index_1 + 25
Incr Atemp
Else
Index_1 = Index_1 - 24
Atemp = 0
End If
Next D_1
Next R_0
Trigger = 0
Pwm1b = 0
Waitus 100
P_lat = 1 : P_lat = 0
P_a = Page_counter.0
P_b = Page_counter.1
P_c = Page_counter.2
Pwm1b = Brightness
Trigger = 1
Return

Really works! And everything is just in code.

What if you connect multiple horizontal matrices?
For D_1 = 1 To Num_matr - does not work

Pluto25 · Feb 19th 2020, 9:25pm

Num_matr should does the job.. You'll make a test?

SAMEGO · Feb 19th 2020, 9:27pm

Yes made the test. On 2 and 3 matrix the same image as on 1 matrix

Pluto25 · Feb 19th 2020, 9:38pm

Same? not one column different? Please Show Code

SAMEGO · Feb 19th 2020, 9:50pm

Const Dy_num_vertik = 1
Const Dy_num_horiz = 3

Const Dy_num_vertik = 3
Const Dy_num_horiz = 1
