Hi Midiboxers!
 
Thorsten's Midibox NG can be a little beast in terms of complexity for me ;)
It would be great if someone can help me.
 
I like to equip my Midibox NG with 16 8-segment led bars. 
Each bar should be controlled with a separate received CC event like this way:
CC value = 0 -> all bar segments off
CC value = 64 -> bar segment 1,2,3,4 on
CC value = 127 -> all bar segments on
 
Due to the conditions of my box, I decided to divide them into two 4x16 matrices (one column = 2x8-led bars)
Every matrix is driven by 3 DOUT-SRs.
Matrix 1
SR1 D7 - D0 are connected to the anodes of LED Bar 1, 3, 5, 7 (column 1-8)
SR2 D7 is connected to all cathodes of bar 1, 2 (row 1)
SR2 D6 is connected to all cathodes of bar 3, 4 (row 2)
SR2 D5 is connected to all cathodes of bar 5, 6 (row 3)
SR2 D4 is connected to all cathodes of bar 7, 8 (row 4)
SR3 D7 - D0 are connected to the anodes of LED Bar 2, 4, 6, 8 (column 9-16)
...
 
But now i am confused how to control the led bars independently via CCs because they are parts of led matrix columns. 
Led matrix patterns?
Each led separately with emu_led_offset?
Range mapping?
 
 
Thanks for any suggestions!
 
Best regards

There is nothing more to say!

I mistakenly missed out the LED Digit topic and thought to have no usecase for it.

Thank you Thorsten.

This was probably a little bit hasty...

The LED Digit example does not clarify the issue because

it is a pair of 8x8 matrices.

I have made a sketch to explain what my problem is.

How can i control led bar 1 with a CC and

led bar 2 with another one although they are in the same column?

I tried to assign two diffewrent patterns but as expected they interrupt each other.

 

DOUT_MATRIX n=1   rows=4   sr_dout_r1=3  sr_dout_sel1=4  sr_dout_r2=5  
DOUT_MATRIX n=2   rows=4   sr_dout_r1=6  sr_dout_sel1=7  sr_dout_r2=8  

EVENT_LED_MATRIX id=1  led_matrix_pattern=1  fwd_to_lcd=1  type=CC chn= 1 cc= 1  lcd_pos=1:1:2  label="1:%3d%B"
EVENT_LED_MATRIX id=2  led_matrix_pattern=2  fwd_to_lcd=1  type=CC chn= 1 cc= 2  lcd_pos=1:1:2  label="1:%3d%B"

LED_MATRIX_PATTERN n= 1   pos= 0  pattern=0000000000000000
LED_MATRIX_PATTERN n= 1   pos= 1  pattern=1000000000000000
LED_MATRIX_PATTERN n= 1   pos= 2  pattern=1000000000000000

Ah! Sorry, I picked up the wrong example.

 

This is a better one: http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fmidibox_ng_v1%2Fcfg%2Ftests%2Ftpd.ngc

(it tests the TPD, which consists of two 8x8 duo-LED matrices, driven by DOUT_MATRIX n=2 and n=3)

 

As you can see, each DOUT_MATRIX has 16 EVENT_LED_MATRIX entries, regardless of the number of rows.

In order to ensure individual access, I would propose to define 4 DOUT_MATRIX items:

/edit: corrected DOUT_MATRIX assignments.

DOUT_MATRIX n=1   rows=4   sr_dout_sel1=4  sr_dout_r1=3  
DOUT_MATRIX n=2   rows=4   sr_dout_sel1=4  sr_dout_r1=5
DOUT_MATRIX n=3   rows=4   sr_dout_sel1=7  sr_dout_r1=6  
DOUT_MATRIX n=4   rows=4   sr_dout_sel1=7  sr_dout_r1=8

you should be able to control the LED bars with:

EVENT_LED_MATRIX id= 1 type=CC  chn= 1 cc= 16  led_matrix_pattern=1
EVENT_LED_MATRIX id= 2 type=CC  chn= 1 cc= 17  led_matrix_pattern=1
EVENT_LED_MATRIX id= 3 type=CC  chn= 1 cc= 18  led_matrix_pattern=1
EVENT_LED_MATRIX id= 4 type=CC  chn= 1 cc= 19  led_matrix_pattern=1

EVENT_LED_MATRIX id=17 type=CC  chn= 1 cc= 20  led_matrix_pattern=1
EVENT_LED_MATRIX id=18 type=CC  chn= 1 cc= 21  led_matrix_pattern=1
EVENT_LED_MATRIX id=19 type=CC  chn= 1 cc= 22  led_matrix_pattern=1
EVENT_LED_MATRIX id=20 type=CC  chn= 1 cc= 23  led_matrix_pattern=1

EVENT_LED_MATRIX id=33 type=CC  chn= 1 cc= 24  led_matrix_pattern=1
EVENT_LED_MATRIX id=34 type=CC  chn= 1 cc= 25  led_matrix_pattern=1
EVENT_LED_MATRIX id=35 type=CC  chn= 1 cc= 26  led_matrix_pattern=1
EVENT_LED_MATRIX id=36 type=CC  chn= 1 cc= 27  led_matrix_pattern=1

EVENT_LED_MATRIX id=49 type=CC  chn= 1 cc= 28  led_matrix_pattern=1
EVENT_LED_MATRIX id=50 type=CC  chn= 1 cc= 29  led_matrix_pattern=1
EVENT_LED_MATRIX id=51 type=CC  chn= 1 cc= 30  led_matrix_pattern=1
EVENT_LED_MATRIX id=52 type=CC  chn= 1 cc= 31  led_matrix_pattern=1

 

Best Regards, Thorsten.

Hi Thorsten,

 

unfortunately your Code

DOUT_MATRIX n=1   rows=4   sr_dout_r1=3  sr_dout_r2=5  
DOUT_MATRIX n=2   rows=4   sr_dout_r1=4  sr_dout_r2=5
DOUT_MATRIX n=1   rows=4   sr_dout_r1=6  sr_dout_r2=8  
DOUT_MATRIX n=2   rows=4   sr_dout_r1=7  sr_dout_r2=8  

EVENT_LED_MATRIX id= 1 type=CC  chn= 1 cc= 16  led_matrix_pattern=1
EVENT_LED_MATRIX id= 2 type=CC  chn= 1 cc= 17  led_matrix_pattern=1
EVENT_LED_MATRIX id= 3 type=CC  chn= 1 cc= 18  led_matrix_pattern=1
EVENT_LED_MATRIX id= 4 type=CC  chn= 1 cc= 19  led_matrix_pattern=1

EVENT_LED_MATRIX id=17 type=CC  chn= 1 cc= 20  led_matrix_pattern=1
EVENT_LED_MATRIX id=18 type=CC  chn= 1 cc= 21  led_matrix_pattern=1
EVENT_LED_MATRIX id=19 type=CC  chn= 1 cc= 22  led_matrix_pattern=1
EVENT_LED_MATRIX id=20 type=CC  chn= 1 cc= 23  led_matrix_pattern=1

EVENT_LED_MATRIX id=33 type=CC  chn= 1 cc= 24  led_matrix_pattern=1
EVENT_LED_MATRIX id=34 type=CC  chn= 1 cc= 25  led_matrix_pattern=1
EVENT_LED_MATRIX id=35 type=CC  chn= 1 cc= 26  led_matrix_pattern=1
EVENT_LED_MATRIX id=36 type=CC  chn= 1 cc= 27  led_matrix_pattern=1

EVENT_LED_MATRIX id=49 type=CC  chn= 1 cc= 28  led_matrix_pattern=1
EVENT_LED_MATRIX id=50 type=CC  chn= 1 cc= 29  led_matrix_pattern=1
EVENT_LED_MATRIX id=51 type=CC  chn= 1 cc= 30  led_matrix_pattern=1
EVENT_LED_MATRIX id=52 type=CC  chn= 1 cc= 31  led_matrix_pattern=1

 

does not work.

Would you please explain it to me?

1) Why are the sr_dout_sel missing or are they just declared as sr_dout_r2?

 

As you can see, each DOUT_MATRIX has 16 EVENT_LED_MATRIX entries, regardless of the number of rows.

2) Do you mean EVENT_LED_MATRIX entry has a 16 step pattern?

 

3) Shouldn't be the code

DOUT_MATRIX n=1   rows=4   sr_dout_r1=3  sr_dout_r2=5  
DOUT_MATRIX n=2   rows=4   sr_dout_r1=4  sr_dout_r2=5  
DOUT_MATRIX n=1   rows=4   sr_dout_r1=6  sr_dout_r2=8  
DOUT_MATRIX n=2   rows=4   sr_dout_r1=7  sr_dout_r2=8

like this (different matrix numbering)

DOUT_MATRIX n=1   rows=4   sr_dout_r1=3  sr_dout_r2=5
DOUT_MATRIX n=2   rows=4   sr_dout_r1=4  sr_dout_r2=5  
DOUT_MATRIX n=3   rows=4   sr_dout_r1=6  sr_dout_r2=8  
DOUT_MATRIX n=4   rows=4   sr_dout_r1=7  sr_dout_r2=8

 

Best regards

Sorry, my fault.

 

It should be:

DOUT_MATRIX n=1   rows=4   sr_dout_sel1=4  sr_dout_r1=3  
DOUT_MATRIX n=2   rows=4   sr_dout_sel1=4  sr_dout_r1=5
DOUT_MATRIX n=3   rows=4   sr_dout_sel1=7  sr_dout_r1=6  
DOUT_MATRIX n=4   rows=4   sr_dout_sel1=7  sr_dout_r1=8

Does this make more sense? ;)

 

 

2) Do you mean EVENT_LED_MATRIX entry has a 16 step pattern?

 

no, I mean that

EVENT_LED_MATRIX id=1..16 are assigned to DOUT_MATRIX id=1

EVENT_LED_MATRIX id=17..32 are assigned to DOUT_MATRIX id=2

EVENT_LED_MATRIX id=33..48 are assigned to DOUT_MATRIX id=3

EVENT_LED_MATRIX id=49..64 are assigned to DOUT_MATRIX id=4

 
each id controls a column (LED bar)
You've only 4 LED bars per DOUT_MATRIX, accordingly only id=1..4, id=17..20, id=33=36, id=49..52 are relevant, the others can be ignored.
 

Best Regards, Thorsten.

Ah now i got it:

this why you count in your tpd.ngc example:

...
EVENT_LED_MATRIX id=22 type=CC  chn= 1 cc= 21  led_matrix_pattern=1  rgb=15:15:15
EVENT_LED_MATRIX id=23 type=CC  chn= 1 cc= 22  led_matrix_pattern=1  rgb=15:15:15
EVENT_LED_MATRIX id=24 type=CC  chn= 1 cc= 23  led_matrix_pattern=1  rgb=15:15:15

# CC 24..31
EVENT_LED_MATRIX id=33 type=CC  chn= 1 cc= 24  led_matrix_pattern=1  rgb=15:15:15
EVENT_LED_MATRIX id=34 type=CC  chn= 1 cc= 25  led_matrix_pattern=1  rgb=15:15:15
EVENT_LED_MATRIX id=35 type=CC  chn= 1 cc= 26  led_matrix_pattern=1  rgb=15:15:15
.....

 and not

...
EVENT_LED_MATRIX id=22 type=CC  chn= 1 cc= 21  led_matrix_pattern=1  rgb=15:15:15
EVENT_LED_MATRIX id=23 type=CC  chn= 1 cc= 22  led_matrix_pattern=1  rgb=15:15:15
EVENT_LED_MATRIX id=24 type=CC  chn= 1 cc= 23  led_matrix_pattern=1  rgb=15:15:15

# CC 24..31
EVENT_LED_MATRIX id=25 type=CC  chn= 1 cc= 24  led_matrix_pattern=1  rgb=15:15:15
EVENT_LED_MATRIX id=27 type=CC  chn= 1 cc= 25  led_matrix_pattern=1  rgb=15:15:15
EVENT_LED_MATRIX id=28 type=CC  chn= 1 cc= 26  led_matrix_pattern=1  rgb=15:15:15
.....

 

Thank you again!

Now it really works like wanted :)

 

 

Have a nice day!
