MIOS_ENC_TABLE compile error

sparx · November 1, 2011

So I added some encoders to my setup, all was fine until I put the MIOS_ENC_TABLE in and now get this error:

"expected '=', ',', ';', 'asm' or '__attribute__' before '{' token"

I'm using the app_skeleton.

Can anyone can tell me whats wrong?

Thanks

I have no idea what exactly you have been doing, so it's a bit difficult to analyze what went wrong. Maybe you should post the relevant code snippet? Use the "Insert Code Snippet" button from the Post menu!

Thanks again.

You forgot to mention the important detail that you are trying to compile the code for MIOS32...

MIOS_ENC_TABLE isn't supported anymore, instead encoders have to be installed with the MIOS32_ENC_ConfigSet() function.

See also: http://svnmios.midibox.org/listing.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Ftutorials%2F014_enc_relative%2F

(especially README.txt and app.c)

In order to assign the encoders to SR6/SR7 (as in your table), write:



  // initialize rotary encoders of the same type (DETENTED2)

  int enc;

  for(enc=0; enc<NUM_ENCODERS; ++enc) {

    u8 pin_sr = enc >> 2; // each DIN SR has 4 encoders connected

    pin_sr += 6; // because Sparx connected the first encoders to SR6..SR7

    u8 pin_pos = (enc & 0x3) << 1; // Pin position of first ENC channel: either 0, 2, 4 or 6


    mios32_enc_config_t enc_config = MIOS32_ENC_ConfigGet(enc);

    enc_config.cfg.type = DETENTED2; // see mios32_enc.h for available types

    enc_config.cfg.sr = pin_sr;

    enc_config.cfg.pos = pin_pos;

    enc_config.cfg.speed = NORMAL;

    enc_config.cfg.speed_par = 0;

    MIOS32_ENC_ConfigSet(enc, enc_config);

  }

[/code]


More MIOS32 programming examples can be found under:

http://www.ucapps.de/mios32_c.html


Don't mix them with MIOS8 examples.


Best Regards, Thorsten.

Thank you, thank you.

Got that going.

No doubt I will be back with more questions...

Thanks again.

I get a similar error, but I'm using MIOS8. Here is the top of my main.c:

MIOS_ENC_ENTRY( 9, 4, MIOS_ENC_MODE_NON_DETENTED), // V-Pot 3

MIOS_ENC_ENTRY( 10, 4, MIOS_ENC_MODE_NON_DETENTED), // V-Pot 7

MIOS_ENC_ENTRY( 10, 6, MIOS_ENC_MODE_NON_DETENTED), // V-Pot 8

MIOS_ENC_ENTRY( 11, 0, MIOS_ENC_MODE_NON_DETENTED), // V-Pot 9

MIOS_ENC_EOT

};

I get a syntax error which just refers to the first '{' token when trying to build.

I have altered the Makefile to include -DDONT_INCLUDE_MIOS_ENC_TABLE as well.

Thanks

Has anyone experienced a similar error? I've followed the codeblocks setup to the tee and now its falling at the first hurdle, which is somewhat frustrating

TK. · January 6, 2013

It seems that this template is expired (it has been created many years ago)

Could you please try this skeleton application instead?

-> http://www.ucapps.de/mios/sdcc_skeleton_v1_1.zip

The sources have to be compiled with the "make" command, see also: http://www.midibox.org/dokuwiki/doku.php?id=windows_toolchain_quickstart

The usage of perl, "mkmk.pl" etc. is not required anymore.

It seems that nobody maintains the old wiki pages :-(

(I'm neither a Windows, nor a Codeblocks user)

Best Regards, Thorsten.

Triffki · January 7, 2013

Thanks, I'll give that a go later

Triffki · January 9, 2013

Finally managed to compile and upload my code. Buttons, encoders and LEDs seem ok, just some noisy pots letting it down by the looks of things. Have got some exams coming up so will leave it for a few weeks

TK. · January 9, 2013

Thanks for the confirmation that it helped! :)

Best Regards, Thorsten.
