programming in C

[cimo]

so i am all set up to build a little application, i am working on OSX and everything seems to be ok, SDCC, Gputils, X-Code.I modified main.c and even got a successful build but there is no syx or hex output.Active target set to "MyProject".

what am i missing?

Hi Simone,

first question:

have you set up the targets like described here:

http://www.midibox.org/dokuwiki/how_to_use_xcode2_as_ide_on_a_mac#about_targets_and_makefiles

1. Target "Makefile"

2. Target "MyProject"

second question:

do the perl scripts in the "/skeleton/tools" directory have the right permissions? Means, they have to be allowed "executable". You can either do this by calling [tt]chmod[/tt] in the terminal or (easier) with the FTP-client of your choice (every FTP client has some infopanel where file-rights can be set easily)

Best,

Michael

hi

yes it was all ok  but i ve found the problem there was a missing line in the makefile script for the project, due to a copy n paste at 5am in the morning! now i get errors but just because i modified the code and something is wrong.

thanks!!

now i ll try to create this little app. (it was in the assembler forum before)

4 buttons with leds

1 pot (pedal

i want the 4 buttons to switch among 4 different parameters (or midi channels) of the pot and having the leds for visual feedback

yeppaaa

so far the buttons are working and the pot as well, very easy

but when i add this code

/////////////////////////////////////////////////////////////////////////////

//  This function is called by MIOS when a complete MIDI event has been received

/////////////////////////////////////////////////////////////////////////////

void MPROC_NotifyReceivedEvnt(
  unsigned char evnt0, unsigned char evnt1, unsigned char evnt2) __wparam
{
  // a note event provides 128 different note values (0..127)
  // in this simple example, each note sets an individual pin
  // for DOUT pin numbers, see also this documentation:
  // http://www.ucapps.de/mios/mios_pin_list.txt

  if( evnt0 == 0x80 || evnt0 == 0x90 ) {

    // 90 xx 00 is the same like a note off event!
    // (-> http://www.borg.com/~jglatt/tech/midispec.htm)
    if( evnt0 == 0x80 || evnt2 == 0x00 ) {

      // Note Off
      MIOS_DOUT_PinSet(pin, 0);

    } else {

      // Note On
      MIOS_DOUT_PinSet(pin, 1);

    }
  }
}

i get these errors

i get these errors

i don't know the mac setup, but it looks like you have a java compiler selected.

build the project without modifying it first...

[bugfight]

also you haven't declared the variable "pin"

[audiocommander]

you can ignore the Xcode internal [tt]sentenv[/tt] stuff, but bugfight is of course right about the "pin" variable.

hi

AC i ve spent the last 2 hours with Jimp in the.. i ve spent the last 2 hours with BugFight in the chat, he was so kind to guide me on a step to step techno-progressive learning curve that led me to have:

-in the first phase all 4 buttons to send MIDI notes and leds to listen to the feedback

-then we moved to assign a variable to the pot CC and change the variable with the buttons, light was added in the 7th    day

now the TODO is

using a single button to change among, let s say 4 or 6 different CC for the pot, with 4 or 6 leds to visualize the status,

keeping the other 3 buttons as normal NOTE ON/OFF

i also need to scale and offset the pot, i am trying to figure out an hardware solution, hardware as modify the pot itself not as a circuitry, but if i fail i ll have to do it in the software.

thanks for your help guys

Hi Cimo

Have you checked out TK's C examples: http://www.ucapps.de/mios_c.html

There's some code snippets here you might find useful. Such a scaling pot values.

Cheers!

[cimo]

hi

yes i ve checked the examples but i can t find the offset code, i think i will have a look at the ACsensorizer
