- The status screen uses the ST7920 character generator to greatly
  reduce SPI traffic and MCU load when updating the status screen.

- Has been tested with the RepRapDiscount Full Graphics Smart Controller
  but should work with any LCD that uses an ST7920 or fully compatible
  controller.

Fix #9530
Fix #9524

Clockwise arrow fixed

minor edits to force new Travis test (last one timed out)

Update u8g_com_HAL_DUE_st7920_sw_spi.cpp

initial power up display garbage gone

* Fixing the DUE serial port assignments: Now -1 means the SAM3x USB Device emulating a serial port, and 0 means the USB to serial adapter included as a programming port

* Improving the Fast IO port access implementation on Arduino DUE

* Implemented EEPROM emulation on Due by storing data on the internal FLASH (with wear leveling)

* Implemented a Software SPI for the ST7920 graphics display for the Arduino RAMPS for DUE, as the default one in u8glib is clocking data too fast on ARM, and the display does not understand it.

* Fixing the case where the serial port selected is the USB device

* Adding configuration for the Makerparts 3D printer (www.makerparts.net)

* Tuned MakerParts acceleration on X and Y axis so it never loses steps. Also adjusted pulses per mm to match default hw configuration

* Fine tuned Maximum acceleration for MakerParts printer

* Style cleanup

* Style cleanup (2)

* Style fixes (3)

* Style cleanup

* Style changes to u8g_dev_st7920_128_64_sw_spi.cpp

* Even more improvements to the FastIO HAL for DUE. Now WRITE() is 2 ASM instructions, if value is constant, and 5 cycles if value is not constant. Previously, it was 7..8 cycles

* After some problems and debugging, seems we need to align the interrupt vector table to 256 bytes, otherwise, the program sometimes stops working

* Moved comments out of macro, otherwise, token pasting does not properly work sometimes

* Improved Software SPI implementation on DUE: Now it honors the selected speed passed to spiInit(). This allows much faster SDCARD access, improving SDCARD menus and reducing latency

* Update u8g_dev_st7920_128_64_sw_spi.cpp

* Disabling EEPROM over FLASH emulatiion if an I2C or SPI EEPROM is present

Possibly more should be brought over? Discussion at #8471

Travis fix - only allow ultralcd_st7920_u8glib_rrd_AVR.cpp to compile when ST7920 selected

changed includes to make Arduino IDE happy

LPC1768 VIKI2 & RRDFG are working

looks like all SPIs are working

library change

sh1106 locks up

fixed lockup, started I2C SW com

pretty

re-org

restore a few files

make library happy

switched HAL version of rrd

fix travis error

travis error fixes

another travis fix

cleanup

minor update

one more

correct spacing in platformio.ini

* Add GFX overlay to UBL mesh edit

Fixed misplaced HAS_TEMP_BED in dogm_bitmaps.h

rename _lcd_babystep_zoffset_overlay to _lcd_zoffset_overlay_gfx and move it out of BABYSTEP_ZPROBE_OFFSET to we can use it for over things. Add this function into UBL mesh edit screen.

update all Configuration.h to add ENABLE_MESH_EDIT_GFX_OVERLAY

* Add Sanity to UBL  insanity

Need to check for DOGLCD  otherwise error out.

Based on #7862, #7846 by @rmoravcik

* fixed some include paths

* LPC1768: Fix Serial API

Add missing serial methods used if TX_BUFFER_SIZE is set
Change return value of HalSerial:read to match Arduino API

* LPC1768: add filters to ADC

This is to try and compensate for hardware issue and oversensitivity to noise

* LPC1768: remove the polling section of delayMicroseconds

* LPC1768: lock usb mass storage device while device accesses it.

Currently only applicable to persistent store,
The device always has priority and will unmount the sd card from the host, Windows then tries to automount again so it can look like the explorer window freezes. Linux Mint, by default, just closes the Nemo window.

* Add timeout to make sure if Serial never connects that Marlin still boots

* Remove unneeded ifdef CPU_32_BIT

In general the need for ifdef CPU_32_BIT blocks means that something is missing from the HAL API or a Platform, in this case HAL_TICKS_PER_US was missing from the AVR Platform

* LPC1768: relocate RE-ARM debug_extra_script.py
