Emilio Moretti be37c38aa2 Fix Ender-2 LCD contrast 
Changed the default to overcome the changes in:
5018fdacbe
This commit exposed a bug because the Ender-2 was using a MINIPANEL lcd
and getting default values that were too low, so the text was too weak.
However, the panel should be MKS_MINI_12864, since it
explicitly sets the correct contrast without relying in the defaults.

Creality Ender Support

This branch is a reverse-engineered version based on the unpublished firmware from Creality. It is not the authoritative source, but has been carefully re-built by looking at their firmware and inferring the base version and configuration they used. The basis is the firmware version from "Jul 31 2017 10:16:30". It is based on Marlin 1.0.1, because

  • 1.0.0 had very different serial output in setup() and overall code structure.
  • 1.0.2 changed the VERSION_STRING to include a leading space, and lcd_init uses SET_INPUT instead of pinMode.

Configurations were found by seeing what code was compiled into the firmware, and constants used there.

For U8Glib, at least version 1.14 and at most 1.17 is used, because

  • 1.12 didn't have the extra speed argument to u8g_InitCom.
  • 1.13 didn't have the soft reset instruction for UC1701 initialization.
  • 1.18 has a new directory structure.

Bitmaps

The bootscreen and custom status screens come from Creality's firmware.

Creality Ender-2 firmware status

The firmware source code has been published on 2018/07/10. It is based on Marlin 1.1. The source code and .hex binaries for all printers (including Ender-2) can be obtained from: https://www.creality3d.cn/download/firmware_c0001

And repositories for CR-10S and Ender-3 can be found here: https://github.com/Creality3DPrinting

The configuration files have been verified to match the original configuration, but further investigation is needed to ensure there aren't any extra changes in the source code.

Ender-2 specific changelog:

  • 2018/10/08 - Updated BED_MAXTEMP to 75 to match the original Creality Ender-2 Firmware (which is now open source)
