Cant get my graphic display to work

Dear people,

I'm a completely noob in the repetier and arduino world. But in the mean time I have read tons of sites/video's/forum etc but I cant solve the problem....

I have a new Megatronic v3 board with the 128x64 full graphical LCD (SPI) screen.
The screen and encoder work good with Marlin. But because of its limitations I want to try repetier (because the milling possibilities).

So I downloaded the repetier firmware today with the web-configuration tool.
I had a working Arduino IDE (1.8) installed, but for repetier I tried version 1.6.5 too (the config file has comments that it is optimised for v0.92).

I also read about the "FEATURE_CONTROLLER 11" had to be defined in the configuration.h file, but that is already the case.
During compiling do not appear any errors.

But whatever I try, the graphics screen stays blank, no tekst or sign of life. Except for its LED :)

What do I have to do next?
I hope you can help me, cause I'm totally out of options by now.....

Thnks! Frank

  • Not all boards have pin definitions for all boards. So I guess that combination is not available by default. If you are using dev version check DisplayList.h for that display and see the pin definitions for the controller for the boards. Add your board as extra case and set pin numbers as connected and it should work.
  • thanks for your answer!
    I studied for hours today, but have no clue.

    I did found out that the graphics screen is recognised as FEATURE_CONTROLLER == CONTROLLER_REPRAPDISCOUNT_GLCD

    That seems oke, since it is a graphic display from reprapworld.
    The megatronics V3 board is from reprapworld too.

    In the repetier firmware I downloaded is no "displayList.h" available, so I have no clue what you told me to do?.

    So now I'm really getting confused: with the repetier firmware are not all pin numbers mentioned (anyway, I cant find them, partially commented but uncommenting has no effect).
    Within the Marlin firmware I cant find the complete IO's too, but there the screen works fine  :)

    So I can only ask: how to deal with it now?
    I collected the settings for the screen and board, with the following pin numbers:

    Keypad header:
    1. 5V
    2. GND
    3. Encoder A (D45)
    4. Encoder Switch (D33)
    5. Encoder B (D44)
    6. Tactile button (D34)
    7. N/C (D43)
    8. SD Detect (D35)
    9. N/C (D42)
    10. N/C (D36)

    SPI header (at the display = SDOUT header at Megatronics board)
    1. 5V
    2. N/C
    3. MISO (MISO pin, D50)
    4. MOSI (MOSI pin, D51)
    5. SCK (SCK pin, D52)
    6. CS SD (SS pin, D53)
    7. GND
    8. SD Detect (N/C)

  • First thing I said is using latest dev version. You are apperently using 0.92.x as there is no DisplayList.h and the contents is in ui.h for that version.

    Looking into dev version I even saw a entry for megatronics3 for the GLCD Display:

    #elif MOTHERBOARD == 703 // Megatronics v3.0

    #define UI_DISPLAY_RS_PIN 32
    #define UI_DISPLAY_RW_PIN -1
    #define UI_DISPLAY_ENABLE_PIN 31
    #define UI_DISPLAY_D0_PIN -1
    #define UI_DISPLAY_D1_PIN -1
    #define UI_DISPLAY_D2_PIN -1
    #define UI_DISPLAY_D3_PIN -1
    #define UI_DISPLAY_D4_PIN 14
    #define UI_DISPLAY_D5_PIN 30
    #define UI_DISPLAY_D6_PIN 39
    #define UI_DISPLAY_D7_PIN 15
    #define UI_ENCODER_A 45
    #define UI_ENCODER_B 44
    #define UI_ENCODER_CLICK 33
    #define UI_INVERT_MENU_DIRECTION 1
    #define UI_RESET_PIN -1

    so maybe it even works out of the box also some pins seem different.
  • Thanks for your reply again :)

    I really didnt understand the dev part, but I understand now I think :)
    So I downloaded this version, but nothing on the screen.

    I see what is going wrong I think:.

    I wrote that I have the Megatronics V3 board and GLCD screen.

    In the dev version is only mentioned pins belonging to the V3.0 board, but I have V3.1 board :)
    As I understand, SPI is a serial comm bus, instead of the straight pins in the V3.0 board.

    What profile is going to used I dont understand, while in more then one places in DisplayList.h are more places the same motherboard (703) is mentioned (all after "#elif"), but some are taken over, others are not ??

    So I tried to copy a LCD setup from another board and I got some tekst on the screen :)
    It is still not correct, since I dont understand well what parameters to use.

    E.g. the SD card on the screen is not correct: it detects a SD card (message in the display), but then the system "freezes".

    In the listing (from the manual in my previous post) I gave the settings in the manual, but what parameters do I have to use with what name?
    Specialli the SPI settings of course, like MISO (50), MOSI (51), SCK (52), CS SD (SS pin, 53),
    but also the Tactile button (34)?

    Underneath the settings I used (but not correct, but as a start):

  • Ok, first trick to see your addition is used is adding

    #error My changes

    so if compilation shows that as error you know that your changes get used.

    Are you sure Megatrocincs 3.1 has changed pins and not just fixed/modified some hardwrae parts?

    The display does use software spi meaning you do not use it with hardware SPI pin. That often makes problems when switching between sd card (using hardware spi).
  • I already used that trick :)
    It does indeed stop there with an error, so "my code" is included.

    I'm sure it is SPI now with the v3.1 board. It is written in the manual too:
    https://reprapworld.nl/documentation/graphicallcd_10.pdf
    https://reprapworld.com/documentation/datasheet megatronicsv3.pdf
    (these are the manuals I got the portsettings wrong - but they are not correct in that manual I think)

    I have a LCD-test programm too, that describes the SPI ("test software") at https://reprapworld.nl/products/printers_printing/autonoom_printen/graphical_lcd_screen_v1_0/ :

    I can "translate" te encoder part to Repetier parameters, but the others are a complete riddle to me:

    From SPI.h:
    #ifdef MEGATRONICS
      /* megatronics */
      #define SDSC 53
      #define SW_BACK 34
      #define SW_ENC 33
      #define ENCA 44
      #define ENCB 45
      #define LCDSC 56

    From SD.h (I suppose for the SD card):
    #ifdef MEGATRONICS
      /* megatronics */
      #define SDSC 53
      #define SW_BACK 34
      #define SW_ENC 33
      #define ENCA 44
      #define ENCB 45
      #define LCDSC 56

      U8GLIB_ST7920_128X64_4X u8g(LCDSC);
      #define SERIALTYPE Serial
    #endif




  • problem smart adapter . I removed the plastic housing from the smart adapter and changed the orientation.
    uniconfig.h //#define U8GLIB_ST7565_NHD_C2832_HW_SPI  // unmarked

    there is an image on my screen but no menu.

  • What are you trying to say?

    Are you now using hardware SPI? That can easily cause interference with sd card. Maybe that causes the hang.In next firmeare version we therefore want to switch completely to arduino SPI library instead of having a mix.
