Trying to compile marlin 2 with platformio.io for the S6 and use a Rep Rap Discount LCD (full graphic smart controller).
I downloaded bugfix-2.0, made the required changes from the Wiki(motherboard etc), I then un-commented out the rep rap discount lcd statement, changed the serial port to -1, u8glib is installed and then it compiled without issue.
I re-positioned the LCD connectors on the board so the notch faces the center (turned around cables).
It also uploaded no problem using DFU mode and vscode/platform io. I also tried SD-Card.
However, I get nothing on the LCD at all other than a black light.
Any ideas? Are the pinouts wrong on the S6 EXT connectors?
Looking at marlin it does not look like the fysetc boards do not have the pins defined for lcd displays other than their own like the fystec 12864mini.
I am guessing I need to add the correct pin definitions to the pins .h file.
