MIOS Matrix

novski · July 26, 2014

Hi

Im Trying to get my Matrix working but have some problems with the commands.

Getting back to this in my Vacation im now testing the self-made board of this Schematic:

Im trying to program it in MIOS but i can't find out why the second and third button row doesn't react. And instead the First row shows all three Values by pressing the corresponding button of the first row.

The LEDs don't light up at all...

Based on the Testfiles i added some helpful code to display the pressed Value but in main its from repository:

Can somebody help me with that?

I had a quick look into the schematic.

It looks like you are using 3 rows for the LEDs, and 3 for the buttons, right?

In this case I would use row=4 for both matrices (DIN_MATRIX and DOUT_MATRIX), so that the row selection signals will be duplicated (visible at D0..D3 and D4..D7)

This doesn't explain why the buttons trigger the events of 3 rows at once, but it might be a good starting point for debugging.

Best Regards, Thorsten.

Hi TK.

Yes thats correct i use 3 Rows for LEDs and 3 Rows for Buttons from the same Shift Register.

I just tryed to change the rows=8 to rows=4 but that didn't change any of the behaviors. I also noticed that the DIN_Matrix line was inverting=1 what i now changed to inverting=0.

Is the schematic done right?

Thank you

best regards, novski

TK. · July 27, 2014

The schematic looks correct.

Maybe an electrical problem?

Are you able to remove the button matrix from the remaining circuit?

Then just connect the row selection signals (IC1 Pin 7, 6, 5) with the column inputs at IC2 with a cable, one after another.

Each connection should trigger an individual MIDI event.

If this doesn't work, connect an alternative DIN and DOUT module (or a MBHP_DIO_MATRIX if available) and check the same.

This ensures that the matrix configuration is correct, and that you know where to continue debugging...

Best Regards, Thorsten.

Hi TK.

Thanks for your reply

I can't swap anything because of the rubber buttons i made all in surface mount on the Bottomside of the PCB...

To me it looks like the column are short but if i measure B1 to B9 its a open line in both sides. also if i push the button B1 while i measure, B1 and B9 are not short connected...

I changed both SR 1&2 but it stays the same. If i press B1 the Value of B1,9,17 goes to Value 127 and all three LEDs lit up. as they should but if they get V127 but i don't know from where they get the V127 because im pressing just B1.

no clue.

i need a beer. :mad:

Try another hardware module (e.g. MBHP_DIN and DOUT module) after the beer ;)

At the bottom of my .NGC it sets every Value in the Collum to 127.

Now it works. :rofl:

Wow. im so glad i found that...

It took me an entire day!

So what was the problem?

novski · July 27, 2014

The tiny line on the end of my script was evil to me today...

EVENT_LED     hw_id=1

Made that when pressing a single button in the first row then all LEDs in that column went on.

You might think its not possible, but it took me a day to realize that... :sad:

Well the wether was not good at all, so didn't miss anything.

Hi

Today i tried a new part of my Fadercore, its a Matrix of 8 rows and 16 LEDs. Purposed to be a LED Level-Meter.

To test, i connected just one Row and 16LEDs and hocked a Encoder to a DIN board. So by turning the Encoder i get a Value from 0 to 127.

Then i wanted to make a simple Test like it wold be LEDs around the Encoder. But somehow again, i don't understand why my code doesn't work.

This is my .NGC file:

LED_MATRIX_PATTERN n= 1  pos=15  pattern=1111111111111111

I see the Value rising but the LEDs are always ON. Also if i turn "inverted_sel=1"

What am i doing wrong?

best regards

Btw.: the EVENT_LED "trick" isn't understood at my side, it should work properly without.

And if now even such a simple DOUT matrix configuration doesn't work at your side (it looks correct), something seems to be totally wrong.

Could it be, that you are using an (old) .NGR script which may overwrite certain configurations?

You've edited the right file, and always checked that MBNG didn't report any error or warning during the upload & execution?

Or you are using a modified firmware build which causes such problems?

Which core module are you using btw.?

im using a LPC1769 since my STM32F4Disco turned out to be the smal brother... :pinch: (its on the way to you now...)

I havent changed or Deleted the Files since a long time so the .NGR was never touched and is empty.

-> i just had to notice that there is a warning and it reports that there is no LED.NGR file.

WARNING: unsupported parameter in DOUT_MATRIX n=1 ... sr_dout_row=1

means: the sr_dout_row parameter doesn't exist.

means: there is no shift register assigned to drive the rows.

means: it makes sense to read in the documentation which parameter allows you to assign the shift register -> http://www.ucapps.de/midibox_ng_manual_ngc.html

means: thereafter there is a higher chance that the LED matrix will work.
