[BUG] Wrong Pin documentation in MKS Sbase README.md
FriedSemiconductors opened this issue · 2 comments
Description:
In the README.md of the MKS Sbase example are notes about swapping pins of the EXP2 connector to get the RepRapDiscount Full Graphic Smart Controller to work.
One of the mentioned pins is the pin P0.5, the pin is not part of EXP2 as mentioned, but instead a pin of the X-Motor driver.
Does another Pin have to be swapped or can we ignore this line? And what are the corresponding target pins on J8, they have a different style of labling (GND; P1.22; P1.23; P2.12; P2.11; P4.28 > see screenshot).
Can someone please clarify, as i am unsure on how to wire it correctly with this information?
I'd really appreciate the help, thank you for your time and have a nice day.
Screenshots:
It should probably be P0.9.
/**
* A custom cable is needed. See the README file in the
* Marlin\src\config\examples\Mks\Sbase directory
* P0.27 is on EXP2 and the on-board SD card's socket. That means it can't be
* used as the SD_DETECT for the LCD's SD card.
*
* The best solution is to use the custom cable to connect the LCD's SD_DETECT
* to a pin NOT on EXP2.
*
* If you can't find a pin to use for the LCD's SD_DETECT then comment out
* SD_DETECT_PIN entirely and remove that wire from the the custom cable.

@thisiskeithb
thank you for clearing this up, that helps a lot.
