Affichage reprapdiscount full et mks gen l 1.0

Bonjour,

avec marlin 1.1.9 et une ender 3 j'ai décidé de changer la carte par la mks gen l 1.0 que j'utilise quand j'ai besoin du bltouch et je voulais utiliser un écran reprapdiscount full graphic.

Après l'installation du firmware je rencontre un problème au niveau de l'affichage mais sinon le reste fonctionne parfaitement, même la carte sd.

voici la photo du lcd



après avoir fait quelques recherche j'ai trouvé une différence entre la mks gen l 1.0 et par exemple la ramps 1.4, toutes les pins sont les même sauf une, pour ramps c'est une ping gnd mais pour mks c'est la pin D17.

Qu'en pensez vous?


nouvelle donnée :21.12 hier soir j'ai installé un :



et avec lui affichage sans problème.

ma nouvelle idée est que le problème vient probablement de la librairie U8glib qui est utilisé par le full mais pas le smart

merci d'avance

Same as [github.com]


add this to Configuration.h
#define ST7920_DELAY_1 DELAY_NS(200)
#define ST7920_DELAY_2 DELAY_NS(200)
#define ST7920_DELAY_3 DELAY_NS(200)

Hello Dust.

A huge wow and thank you for your help, I'm very happy to see that there are some new great 3d printers out there.

Hello everybody
This is my first message on this forum.
Not exactly the same problem as @maximeh but maybe something similar and @dust will have an idea
I am changing my board from Arduino/Ramps to MKS SGEN_L V1.0 on a FreeSculpt printer
The display is REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
Marlin Bugfix compiled OK on Platformio
Everything is OK but...
When I want to access the SD Card for printing, the system displays the content of the internal micro SD instead of the one inserted into the screen
This not handy, the MKS is underneath....
Thanx for looking

@Flying_Hammer

With a lot of 32bit controllers there are onboard and lcd based SD cards

/**
     * Set this option to one of the following (or the board's defaults apply):
     *
     *           LCD - Use the SD drive in the external LCD controller.
     *       ONBOARD - Use the SD drive on the control board. (No SD_DETECT_PIN. M21 to init.)
     *  CUSTOM_CABLE - Use a custom cable to access the SD (as defined in a pins file).
     *
     * :[ 'LCD', 'ONBOARD', 'CUSTOM_CABLE' ]
     */
    //#define SDCARD_CONNECTION LCD

You need to enable #define SDCARD_CONNECTION LCD In Configuration_adv.h

Gimme five, @Dust !

It works like a charm.
It was a good opportunity to discover this forum I have immediately bookmarked
Now, I have reading at least until Christmas

Next project : 4 axis laser engraver

N-1 project : 3 axis CNC, done

GOTO presentation topic ! *
