Sbase: spi_pins.h after sbase_pins.h interference.BUG

Bug Report

define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

1 Current spi pins are matched into display pins and cause picture artefacts. 2 Some displays use SPI so these pins must be redefined after spi_pins.h 3 SDcard on display's cardreader still does not init with any pin compinations I tried.

My spi_pins.h

#ifndef SPI_PINS_LPC1768_H
#define SPI_PINS_LPC1768_H

#define LPC_SOFTWARE_SPI

This is a well-known issue with all LPC176x-based controllers, and is the reason that the external SD card included with LCD displays is unsupported in Smoothieware.

This "well-known issue" does not exist actually. ( Yes I know about some other opinions).

BUT, I have seen personally about 100 delta printers (sold and in production) ) that works on external sdcard perfectly. More over, we does not recommend our users to use USB connection at all and external sdcard is the only user accessible.

MSK Sbase. DIsplays are GLDC and RRD Smart controller ( identical card reader).
