  1. lcd ssd 1306 1.3" _ wants 1 pixel offset

    in MIDIbox NG

    Posted

    hello ,

    after a few problems my LPC_ NG is running again.

    im wondering if there is a way to offset the display ( shift to the right ) by 1 or 2 pixels .

    since my  1.3" SSD1306 are shifted 1 (or 2?)  pixels to the left .

    if im doing the offset via ngc ( which would be a workaround ) im losing a couple more pixels . ( since shifting the letters one position to the right , id loose a letter )

    in  mios32_lcd.h  the offset is "forbidden"   ( it says   :   // fixed format, dont change! )

    is there a way to do this , other than via ngc ?

     

    ps : im happy to be back working on this after many years  :)

    Thank you ,

    im measuring something similar .

    so this seems normal .

     

    i can replicate the behaviour now and i hope this will help to track down my problem .

     

    when i connect my core with NG 1.036 to a external psu ( no usb data connection ) the app / core  is always starting properly .

    when i connect the core to usb ( as long as there is no data handshake with mios , ableton or any software ) it will boot fine .

    when the core is connected to usb (power) and i start mios or any other app on the mac (e.g. ableton , logic etc ) the core is crashing.

    the hard fault adress is always 0x000189ce .

    i can workaround this crash if i boot with "Bootloader HOLD Mode jumper" and remove the jumper afterwards.

    how can i find out about the hard fault adress ?

     

    ps . you are right about "disable UART.." from config file .

    this is preventing the hard fault (as well) .

    but then i loose the midi in / out ( 5 pole DIN )    :(

     

    actually after reactivating UART and reducing encoders ( from 125 to 33 ) as well as reducing aout channels (from 32 to 8) , the hard fault seems to have vanished.

    i still would like to know how to find and identify the hard fault adress

    hello again .

    i also have hard faults with 1.036 now .

    but only every 2nd or third time i reconnect the usb cabel .

    im wondering if maybe something got seriously damaged .

    how warm will the lpc get usually ?

    the mcu is getting warm . i can still touch it but im wondering why it is warm at all with such small duties .

    this is the normal official release from the download page .

    is there a way to identify the hard fault adress ?

    Thank you for all your effort .

    I was really getting frustrated .

    _

    this is really sad news , since i was actually working with this release . now i cant compile any more.

     

    UART here , has either something to do with Ethernet / RS-232 Interface or a Serial Connection ?

    i will check if i can use the release properly without UART .

    ok, cant say what the display says (since it there is no) but the board led is blinking rapid. and mios studio does not recognize the board.

     

    i tested it on the LPC-Core, plugged into my laptop

    when i plug the usb-cable to a wall-5V adapter, its not  blinking.

     

    so yes - this is a software thing, not a hardware.

     

    about mios-config... there is a lot activated.... do you use all the things in there? (#define MIOS32_SRIO_NUM_SR 32    and so on...)

    so this means , its better to edit the mios-config , before i compile ,right ?

    I suddenly have a Hard Fault 0x00018fc2 when powercycling and booting NG via USB Power / USB Data Connection.

    If the bootloader jumper is connected i can use the USB Connection to upload the bootloader . but after uploading NG  again and rebooting , it wont boot back up after power cycling the USB Connection.

    The App will boot properly with external power and detached USB cabel.

     

    this suddenly occured

    i use a self powered usb hub .

    i tried disconnecting all attachments ( sdcard , scs ,etc .. ) but that does not change the behaviour.

    I also recompiled the hex and tried again , but no luck.

    does someone have a guess ?

  18. adding new fonts is not working anymore ?

    :happy:

    ich hätte da noch eine andere Frage .

    Bisher habe ich mit einem LPC Core gearbeitet.

    Es soll aber demnächst auch ein STM32F4 Core her .

    Muss ich die Toolchain um die apps zu compilen dann jedesmal umstellen .

    e.g

    export MIOS32_FAMILY=LPC17xx
    export MIOS32_PROCESSOR=LPC1769
    export MIOS32_BOARD=MBHP_CORE_LPC17

    ..

    export MIOS32_FAMILY=STM32F4xx
    export MIOS32_PROCESSOR=STM32F407VG
    export MIOS32_BOARD=MBHP_CORE_STM32F4

    oder kann ich 2 Toolchain profile haben (mit verschiedenen Pfaden )  ?

    lg ,

    jascha

    im checking your folder and file structure and reading the .c , .h and make files. ..and comparing things with how i did.

    im beginning to see the light . i was not aware of the folder structure  . in fact i have very little knowledge of programming .

    i just downloaded the complete trunk from github and went to :

    mios32/modules/glcd_font        ( to add my xpm and .c files and change the files : glcd_font.mk & glcd_font.h accordingly )

    and

    mios32/apps/controllers/midibox_ng_v1/src    ( to change mbng_lcd.c )

    then i cd into  /midibox_ng_v1  and "make"

    then i got the error from mbng_lcd.c  ( which is referring to <glcd_font> )

     

    - as i see you have everything in one folder

    but you dont use glcd_font.mk (because you adressed the fonts directly in your folder / from your "makefile" ?)

     

    ----!!!!

    i think i understand now what the problem is .

    my building environment is always referring to my old /svn directory . ( since i just started again after many years to work with all that things )

    i will move the new github trunk to the /svn folder and get rid of the old trunk.

    lets see , i think this should fix it .

    ( you are helping me a lot to understand the whole "c compiling / folder structure)

    thank you very much for your reply .

    the high and low letters didnt change the problem.

    i named everything exactly like in the originals.

     

    i now tried to just exchange one of the originals with my font files und renaming them .

    the strange thing is , it compiled properly but the font did not change after the upload .

    seems im stuck .

     

    THIS NOTE makes me wonder . does it mean they are precompiled ?

    Some prepared Fonts/Icons are located under $MIOS32_PATH/modules/glcd_font
    They are already compiled into the project if a GLCD driver has been
    selected (no need to extend the Makefile)
     
    o GLCD_FONT_NORMAL (6x8 character set)
    o GLCD_FONT_SMALL (4x8 character set)
    o GLCD_FONT_BIG (16x24 character set)
    o GLCD_FONT_KNOB_ICONS (28x24 round knobs, 12 different icons)
    o GLCD_FONT_METER_ICONS_H (8x28 horizontal meter bars, 28 icons, 14 with/14 without overload marker)

    o GLCD_FONT_METER_ICONS_V (32x8 vertical meter bars, 28 icons, 14 with/14 without overload marker)

     

    i took a fresh trunk , put my own lcd files , renamed everything according to the present .c and .h files and compiled .

    still the big font ( the one i exchanged ) is the same as in the original .

    how is this possible ?

    are the font files cashed somewhere ?

    i also went to the bootloader and initialized the glcd .

    i dont understand where its getting the font from if the glcd_font files have been changed ( they have the same names to be able to compile ) .

    hey ,

    while i was following this tutorial .

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

    it seems its not allowing me to add a new font .

    is this because the trunk is precompiled ?

        return -1; // unsupported font
      }

    ----> the other files have been changed and added as well

    Could someone please point me in the right direction .

    What am i missing ? do i have to precompile everything to make this work ?

    thanks a lot for time and effort in advance.

    Hi Marcel, welcome abroad!

    I just want to say high to you!!!, unfortunately I can't help you with this problem, as I'm working on MBCV2 with a LPC board, see pic.

    It's been some time since I last played with it. I started to addapt the Lemur template for my Samsung Galaxy S5 and came quite far. I have to dive in it again.

    I heard good stuff about your DIY CNC machine, I'm really curious!

     

    Sorry for interupting your question/problem, good luck with your LCD!

    Cheers,

    Roel

    what is the psu on this photo ? specs ? where to get it ? it has +12 -12 gnd and 5v ?

  25. SCS display and ssd1306

    in MIDIbox NG

    Posted

    hey . 

    i am slightly confused about the lcd options on ng. its stated in ng options that its not possible to mix up clcd with oleds or other displays . 

    i want to build a controller with 16, 24 or even 32 encoders with a dedicated ssd1306 each .

    i´d like to have the standard control surface on this controller as well . but as the 1306 are way to tiny to work as a display for SCS how can i achieve this ?

    i thought about using other oleds like 1325 for scs (as they come as big as 3.1 inch) but still the controller will be different to the 1306. 

    is there a way of having the scs with a big display and the 1306 for the encoders ?

    thanks for any help in advance
