RepRapDiscount full graphics smart controller problem.

 


Problem: 

When use the LCD graphic to connect with ramp1.4, with Marlin 1.1.x firmware. The above error occured.

Solution

1. Define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER from Configuration.h 2. Install u8glib Version 1.15 3. change the file ultralcd_st7920_u8glib_rrd.h at Marlin folder from //#define ST7920_DELAY_1 DELAY_NS(0) //#define ST7920_DELAY_2 DELAY_NS(0) //#define ST7920_DELAY_3 DELAY_NS(0) to #define ST7920_DELAY_1 DELAY_NS(0) #define ST7920_DELAY_2 DELAY_NS(200) #define ST7920_DELAY_3 DELAY_NS(0) 4. compile&upload
