How do I connect one plug (EXT3) LCD 128x64?

This is similar to: Issue 612 except this LCD has 1 plug (EXP3).

Using this code:
[display]
lcd_type: st7920
cs_pin: P0.16
sclk_pin: P0.15
sid_pin: P0.18
encoder_pins: ^P3.25, ^P3.26
click_pin: ^!P1.30

Trying to use CR-10 with a MKS Sbase 1.3. The CR-10 came with a 128x64 lcd (pic attached). The thing is, it has only one plug (EXP3) which worked perfectly with the Melzi board which came with the CR-10. How do I use it with the MKS Sbase 1.3? Most of the things I could find online are of 2 plugs (EXP1 and EXP2).

Just wanna confirm that I have a RepRap Discount LCD 128x64 (2 plugs flipped) and the above code works perfectly well but tried using the One Plug lcd on EXP1 flipped but does not work.

Hi @scarecrow2k6,

It did not look like there was a Klipper log file attached to this ticket. The log file has been engineered to answer common questions the Klipper developers have about the software and its environment (software version, hardware type, configuration, event timing, and hundreds of other questions).

Unfortunately, too many people have opened tickets without providing the log. That consumes developer time; time that would be better spent enhancing the software. If this ticket references an event that has occurred while running the software then the Klipper log must be attached to this ticket. Otherwise, this ticket will be automatically closed in a few days.

For information on obtaining the Klipper log file see: https://github.com/KevinOConnor/klipper/blob/master/docs/Contact.md

The log can still be attached to this ticket - just add a comment and attach the log to that comment.

You'll need to find the schematic for your board, find which pins are mapped to the EXP1 header, find the pins on the CR-10 display, and then map the equivalent pin to the equivalent function in the config file.

If you can obtain the correct mapping, we can add an example to the Klipper config file for future users.

FYI - it doesn't appear one can connect the single EXP1 plug directly to the SBase, as the SBase doesn't route all the pins on that connector. It may be possible to use jumper wires (or similar) to make a custom connection between lcd and board.

I'm going to close this issue as it appears the conversation has concluded.
