Midibox CV Syntax Error

MIOS programming (Assembler)
1

I am trying to compile the Midibox CV application using code offered for DOUT triggers in the Wiki here:

http://www.midibox.org/dokuwiki/doku.php?id=how_to_use_midibox_cv_with_a_dout

I am getting a “syntax error” on this line:

IFNEQ	MIOS_PARAMETER1, ACCESS, rgoto USER_MPROC_NRE_NoNoteChn1

The compiler doesn’t return any errors if I comment out this line (but I’m guessing then my triggers won’t work.  :-[)  Any clues?  My MIOS coding skills are nothing right now, so I’m not even sure what I’m looking at.

IFNEQ won’t work with gputils anymore

Replace the line by

   cpfseq MIOS_PARAMETER1, ACCESS
   rgoto USER_MPROC_NRE_NoNoteChn1
[/code]









Best Regards, Thorsten.

Worked!  Thank you so much.

I posted about asking how to change the Midi Channel from Ch. 1 to Ch. 16 in the “Design Concepts” forum, but I realize it may be better off moved here, in case you want to move it.

Should work if you replace 0x80 by 0x8f, and 0x90 by 0x9f

See this page for details about the MIDI protocol:

Don’t be afraid to update that wiki page too, to save others this trouble in future. If you don’t have time to fix the code, perhaps you can link this thread or something… Thanks!

Cool, I will do that as soon as I get this working!  I think I have burnt shift registers, because I’m getting nothing on my DOUT pins even with the DOUT test application – ordering more today.

It would be cool to add an extra menu page allowing you to route the DOUT triggers to whatever values you liked, maybe I’ll try to tackle that in the future.  It’d also be nice to be able to select whether or not a specific DOUT is a 1ms trigger or a regular gate.

Did you check the SRIO with the test app? all broken SRs would be very unlikely. Soldering errors on the SRIO lines are far more common.

Well my DIN board (which is just a single shift register exactly as detailed in the schematic) is working fine.  I have checked all the connections successfully from the pins on the shift register back to the PIC, and from the shift register to my DOUT pins… everything is fine.  I only have the one DOUT shift register at the moment, so if it’s bad, it’s just a single one bad and not a whole chain… only other thing I can think of is the PIC has a bad pin, but that doesn’t seem likely. 

I will check out that SRIO test app… the one I was using is the DOUT test app.

Sorry it took me a while to revisit this.

I got the code working and updated the wiki articles with the new information:

http://www.midibox.org/dokuwiki/doku.php?id=how_to_use_midibox_cv_with_a_dout

I also updated the code in the German version of the page, but did not add the information on changing the MIDI channel, mein Deutsch ist sehr schlecht. :stuck_out_tongue:
