add ZONESTAR_LCD on RAMPS and REARM warning #20702
add ZONESTAR_LCD on RAMPS and REARM warning #20702
Conversation
This breaks the CI build of a ramps with a zonestar.... not sure best way to deal with this conflict of interest. |
that should do it. ZONESTAR_LCD CI test move onto a non RAMPS board. |
Hey, |
All ADC pins on the LPC176x are not 5v tolerant. So the zonestar lcd will not work without modification. |
Requirements
A RAMPS or derivative with a RAMPS AUX2 port layout
A ZONESTAR_LCD
Description
Directly plugging the zonestar lcd into the RAMPS AUX2 port with the standard straight through cable will connect the RAMPS 5v to the LCD GND pins and the RAMPS GND to the LCD 5v pins. This is not at all desirable.
These pins need to be swapped over in hardware.
Added an Error condition into the pins_RAMPS.h to warn the user about 5v and GND needing swapped.
Benefits
Warns users about needing to swap the 5V and GND pins with this combination of hardware.
