<h2>---------------------------------------------------------</h2> <h2>English version</h2><br /> Be cautious! To utilize this display, you must make some hardware modifications to the wires and connectors. !!! If you are unsure, it is advisable to keep your fingers off of this change. Your motherboard may be damaged in certain circumstances!!! </br> <h2>-- Hardware changes --</h2></br> <ol> <li>You need to cut the nose off of the connector "LCD" because you have to install it in the opposite direction to the SKR 1.3 "EXP1" connector.</li> <li>The wire for +5V (Pin2) and the wire for GND (Pin1) at the LCD connector must be swapped. (Keep in mind, this is the critical Part!)</li> <li>The "CLK Signal" (Pin9) at the LCD connector must be rewired to (Pin7) at the LCD Connector. After the modification (Pin9) has to be open because on SKR 1.3 Mainboard this pin is open drain.</li> <li>The reset switch at the Display is wired to (Pin7) at connector "J3" at the display. You only need a single wire to connect (Pin7) at "J3" from the display to (Pin3) at "EXP2" at the Mainboard.</li> </ol></br> <h2>-- Software changes --</h2></br> <ol> <li>In Marlin 2.0.x Bugfix you have to edit Configuration.h, search for string #define ANET_FULL_GRAPHICS_LCD change it to: #define ANET_FULL_GRAPHICS_LCD</li> <li>You also have to edit Marlin/Marlin/src/pins/lpc1768/pins_BTT_SKR_V1_3.h, Search for string #error "CAUTION! ANET_FULL_GRAPHICS_LCD and add "//" before it to disable the error and warning message.</li> <li>Now just recompile and load the new code on the Mainboard.</li> </ol><br /> <em>No support is provided for using Marlin, the Arduino IDE, Atom or Platformio. I assume that these knowledge are available. I will not answer any questions related to this matter.</em> <br /> <H2> !Disclaimer! Please be aware, I do not accept any liability for damage to your hardware!</H2> <H2>Update 01.12.2019 My changes in the pins_BTT_SKR_V1_3.h are now included in Marlin. The guide has been updated accordingly. German version added.</h2>
