[Display 12864 on SKR E3 Mini] How to adapt the BTT 12864 v1 at SKR E3 Mini V3? #650
Comments
Hi @radek8, thank you for the answer. I tryed your pinout, but it doesn't work. 😢 The led turn on, but nothing is showed in the screen. I tested it using "CR10_STOCK_DISPLAY" on Marlin, and after that also i tryed "MKS_12864" |
What model of display do you have exactly? |

I got this error on VS Code: In file included from Marlin\src\lcd\dogm\marlinui_DOGM.cpp:42: |
You have a different version of Marin than I do. I wrote that you have to comment on line 261. |
line 261 leave uncommented You have to comment on the line I took // #error "CAUTION! FYSETC_MINI_12864_2_1 and clones require wiring modifications. See 'pins_BTT_SKR_MINI_E3_V3_0.h' for details. Define NO_CONTROLLER_CUSTOM_WIRING_WARNING to suppress this warning" |
Man, it's working!!!!! :DDDD I tryed the latest version of marlin and did exactly what you said, and it's working!!! Really thank you! I just need to finish the test regarding neo pixel, but the image is aleady on the screen. Finishing i post the result's here and i will make a video to help another people. Thank you a lot radek!!! I'm almost buying another display. |
Unfortunately, this is an atypical display for this board. |
No problem if the SD or buzzer wont work. About the Neopixel, i uncommented the lines regarding that, and RGB backlight is working. But i facing another problem. When the pin DIN is connected to LCD, the display doesn't show anything, only the RGB backlight work; if i disconect the DIN pin, the backlight doesn't work, but the image is showed on the screen. Maybe could it be a contrast setup? At monday i will buy a flat cable and new connectors to make a permanent cable, i'm using wire jumpers to make the conection today. Monday i'll be back here with more news about the display :D |
The BTT manual introduces another parameter change. You can try ... |
I found another configuration for your display. If you need to change the RGB-color manually, then you need to enable the LED_CONTROL_MENU in configuration_adv.h. If you don't need it, you can skip this step. |
I changed this function and all is working!!! Really thank you man! |
Congratulations, you endured a successful end. |
Hello, |
Ive double checked my wiring and I have what you show above. Reset button isn't working. Wondering maybe, if KILL_PIN needs to be defined in marlin for reset to work ? |
@Wavegreen |
@radek8 thanks for your reply! It looks extremely similar to the BTT 12864 display without reset button and sd card reader. I did try the connections of that screen with mine but haven't had any luck. I did double check connections but it is possible that I made an error of course. |
In the sample configuration for CR-20 it is defined: |
@radek8 any idea on my issue above (from 5 days ago)? Is that normal behavior for this setup? Or do I just have something wrong? Thanks! |
I do not own this display or this SKR board. |
Can you try initializing the EEPROM? |
Hello |
@radek8, Hello, I am unable to connect my BTT 12864 v3 to my skr mini e3 v2, do you know how to connect? |
BTT 12864 v3??? |

@radek8 deu esse erro In file included from c:\marlin-bugfix-2.1.x\marlin\src\hal\hal.h:30:0, Environment Status Duration STM32F103RC_btt_maple FAILED 00:00:59.579
|
@lipe1234645 You have to download Marlin. A common mistake is to download a new Marlin and copy the configuration file from the old version of Marlin into it. |
@radek8 Eu tentei compilar novamente e deu certo, só o display que não aparece nada |
Use English. |
@PangiLukas You would have to use a Y cable. |
I have alright mks tft32_L v4.0 can it work? |
The MKS LCD12864B V1.0 display will work in Marli mode. |
The TFT display will also work but it will be connected via the serial port. In Marlin, you have to activate the serial port and set the communication speed to the same as that of the TFT |
Yeah, all this setting i still do. But at lcd is not show, it only light up. If there is no way to configure with working sd.it is not usable for me. I try to find display from btt. Thanks for all @radek8 |
You misunderstood me. The second option is to use the SD card on the TFT touch screen. |
So for tft 32 its enough to connect via tft serial port 5v/gnd/tx/rx and in firmware set number of serial port and baudrate? |
Yes |
Hello, I have the same bad decision on my hands. |
Unfortunately, I have no experience with Klipper |
mail me at info@lab4450.com so we can figure this out together. |
Hello Guys.
Recently i bought the SKR E3 mini V3 and a BTT 12864 display. But after bought that, i saw that's incompatible. :(
So, i started to search about the BTT display pinout and SKR E3 pinout. I found this pinout below:
So i connected the respective pins of BTT on SKR, and i tested all compatibles displays on Marlin, but it doesn't work :(
I think that to display the most important pins are: LCD_RST(D4), LCD_CS(EN), LCD_RS, 5V and GND. The display turn on the backlight led, but no show anything.
I would like to know if somenone knows if there's a different protocol on BTT display, because SKR support some 12864 displays. Or what is the model of de uC that control de LCD.
I already tested the connection sugested to SKR E3 1.2 and 2.0 and it doesn't works too. :/
Someone to give some support to me? :D
