Set of controler names + BankStick

[goule]

Hi all, back in the midibox universe  ;) just have to finish my OS ...

I have several MIDI sensors and until now every name was saved like this :

const char CTL_NAME[17][16] = 
{
 "Joystick 1 X    ",
 "Joystick 1 Y    ",
 "Joystick 2 X    ",
 "Joystick 2 Y    ",
 "Joystick 3 X    ",
 "Joystick 3 Y    ",
 "Joystick 4 X    ",
 "Joystick 4 Y    ",
 "Pitch Bend Wheel",
 "Modulation Wheel",
 "DBeam Left      ",
 "DBeam Right     ",
 "Basic Knob 1    ",
 "Basic Knob 2    ",
 "Ribbon Ctrl V   ",
 "Ribbon Ctrl H   ",
 "Expression Pedal"
};

Now I want to be able to edit/store/read those names in the BankStick. The problem is when I want to create the structure that will be receiving the data from the bankstick : if I create that kind of things ...

unsigned char CTL_NAME2[17][17];

... I get the error message "no target memory available", even with this simple command.

I can easily manipulate BankStick but do I have to read it every time I want to display the name of the controller that has been touched ??  :-\ :-X

Thanks for helping !

Ok, what I'm gonna do is split each controller name into 2 parts, something like this :

unsigned char NAME_PART1[17][8];

unsigned char NAME_PART2[17][8];

Much more simplier than to split into 2 groups of controllers, as the process is mostly the same for each controller.

BTW, if anyone gotta better idea ...  :P ;D

Peace,

Hi Goule,

welcome back! Just added you to the programmers group ;)

If you reduce the strings to 15 characters + terminator (CTL_NAME[16][8]), it will fit into 256 bytes, and it will also be easier to integrate this into a BankStick structure (2^n bytes should always be prefered)

Best Regards, Thorsten.

Unfortunately, 17 is my number of controllers ... gotta keep this one  :-\

But I could choose to go with CTL_NAME[17][15] as 17*15=255 ...

This would let me 14 characters (+1 term.) for the name.

But I already coded the read/write stuff for the splited name structure :

Reading :

for (ctl=0; ctl<17; ctl++)
{
    for (cpt=0; cpt<16; cpt++)
    {
        octet = MIOS_BANKSTICK_Read((ctl << 4)+cpt);
        if (cpt<8)
            CTL_NAME_PART1[ctl][cpt] = octet;
        else
            CTL_NAME_PART2[ctl][cpt-8] = octet;
    }
    CTL_NAME_PART1[ctl][8] = '\0'; // On insère les bons terminateurs
    CTL_NAME_PART2[ctl][8] = '\0'; // de string sur les fins des 2 tableaux
}

// 3) CTL_CC[] :
for (ctl=0; ctl<17; ctl++)
{
    CTL_CC[ctl] = MIOS_BANKSTICK_Read(272+ctl);
}

and writing :

for (ctl=0; ctl<17; ctl++)
{
    for (cpt=0; cpt<16; cpt++)
    {
        if (cpt<8)
            error |= MIOS_BANKSTICK_Write((ctl << 4)+cpt,CTL_NAME_PART1[ctl][cpt]); // << 4 = *16
        else
            error |= MIOS_BANKSTICK_Write((ctl << 4)+cpt,CTL_NAME_PART2[ctl][cpt-8]); // << 4 = *16
    }
}

// Ecriture des n° de CC
for (ctl=0; ctl<17; ctl++)
{
    error |= MIOS_BANKSTICK_Write(272+ctl,CTL_CC[ctl]);
}

MIOS_LCD_Clear();
if (error) 
{
    MIOS_LCD_PrintCString("Erreur BankStick");
    MIOS_LCD_PrintBCD3(error);
}
else
    MIOS_LCD_PrintCString("BankStick OK    ");

Any comments appreciated to get things even better  ::) ;D

Btw I hope it is not too  :-X for you ...  ;D
