Send sysex to LCD

[FantomXR]

Hi,

I want to print a text message on the first display which is connected to the core via a sysex file.

I'm wondering if there is a tutorial or example for that.

I want to know how to set up the ngc and the sysex file.

I really appreciate your help.

Thanks,

Chris

hi i tried a couple tests to see how this SYSEX works on MB_NG

 

you can do this on a couple on differnt ways...

you can allready find some parameters on Ucapps.

 

but to give you a example i did this...

 

On the .NGC i used this line..for testing

 

EVENT_Receiver  ID =3  type=SysEx  stream="0xf0 0x00 0x30 0x00 ^txt"  LCD_POS=2:1:2
EVENT_Receiver  ID =4  type=SysEx  stream="0xf0 0x00 0x31 0x00 ^txt"  LCD_POS=2:10:2
EVENT_Receiver  ID =5  type=SysEx  stream="0xf0 0x00 0x32 0x00 ^txt"  LCD_POS=2:20:2
EVENT_Receiver  ID =6  type=SysEx  stream="0xf0 0x00 0x33 0x00 ^txt"  LCD_POS=2:30:2

 

0xf0 = Begin of massage

0x00 = Null (No clue just looks nice)

0x30 = 1 (i  use this like a ID) you can also just create something you like to have..

0x00 = Null (realy imported to put this on the end otherwise you'll get strange results)

^txt = for the MB_NG so it knows that is is a Tekst..

 

 

now i use Bome's midi translator to send the SySex string..for testing.

 

F0 00 30 00 54 45 53 54 30 F7 (this will print "TEST0" on the lcd)

F0 00 31 00 54 45 53 54 31 F7 (this will print "TEST1" on the lcd)

F0 00 32 00 54 45 53 54 32 F7 (this will print "TEST2" on the lcd)

F0 00 33 00 54 45 53 54 33 F7 (this will print "TEST3" on the lcd)

 

but as you see i put the LCD:Y:Z on the .NGC but you can also add this to the Sysex string..

 

 

i hope this clears it up for you..

Hey people,

I have another question on this... I don't have any displays here to test... so I thought asking may be faster ;-)
Is it possible to send pure text to the displays without converting them into hex first? If yes, how would this be done?

Thanks!

I guess that you want to send text from one MIDIbox to the display of another MIDIIbox w/o the need to specify the text as hex numbers?

No, this isn't supported (yet)

No, not really. I want to send a text message from my DAW to the MIDIbox. ;)

Then your DAW has to translate the ASCII characters to values which are put into the SysEx stream

Or you could generate the values at this website: https://www.branah.com/ascii-converter

Hey people,

one more question on this:
I'd like to clear a specific OLED before displaying the received text. How to achieve that? My problem is: If the newly received text message has less characters than the old, the non-overwritten characters will stay there. I tried a few different things like label=%C, etc. but this is not working at my side. 

Also it would be enough, if NG just adds some spaces after a received message. So I tried stream="0xf0 0x11 0x22 0x33 0x00 0x00 ^txt 0x20 0x20 0x20 0x20 0xf7" which should output 4 spaces after the text-message... but that's not working.

Any suggestions?

Thanks!
