Full Graphic Smart Controller

Based on bkubicek idea and STB's DOGM implementation, we realized this full graphic smart controller.

Description

This Full Graphic Smart Controller contains a SD-Card reader, a rotary encoder and a x 64 dot matrix LCD display.

The RepRapDiscount_Smart_Controller is a similar design with a 20x4 character based display.

This display board is intended to provide an easy and simple solution to interact with a 3D printer. Given that many of the 3D printer's mainboards are based on the RAMPS design this display board is supported by many other mainboards.

When using a RAMPS board the Full Graphic Smart Controller is simple to connect using the "smart adapter" which connects directly to an Arduino Mega The Full Graphic Smart Controller comes with a (x64) LCD.

Depending on the vendor you may find boards using an ST IC Driver or a ST IC Driver. Boards using a DOG-M Display use a ST IC Driver. The more common and generic boards use some flavor of a LCD with the ST, this is the case with most board you find in online stores.

The original design supports the 8bit Parallel display interface and a 4bit serial display interface, yet all of the common E3 Printer firmwares only support the 4bit Serial interface which only uses one pin for data, freeing more pins for other uses. The preference of serial is mainly due to the use of the [U8G library](eunic-brussels.eu) that implements the graphic support in these firmwares.

This display board is supported by the most popular 3D Printer firmwares, yet differences in the LCD Drivers used and others may dictate the level of support in a given 3D printer mainboard and firmware combination. See connection for more details.

Original Design and Clones/Variants

The original design supports the 8bit Parallel interface and a 4bit serial interface. Many clones or variants only support the serial (SPI) interface.

Variants of the design may have fans or remove the SD-Card, among other changes.

Some budget clones may have issues due to timing constraints with the display used.

Depending on the vendor you may find boards using an ST IC Driver, a ST IC Driver, or other. Boards using a DOG-M Display use a ST IC Driver. The more common and generic boards use some flavor of a LCD with the ST, this is the case with most boards you find in online stores.

Connection

The board has two pin (2 row with mm pitch) box connectors marked EXP1 and EXP2 (PIN IDC CONNECTOR).

The following figure shows the pinout mapping to an Arduino Mega

When used with a RAMPS board the "Smart Adapter" provides an easy connection with the RAMPS. The following figure shows the pinout mapping to an Arduino Mega

Clones and other manufactures may provide different connections, in particular models without SD-Card or models supporting only the SPI/Serial interface (most common)

As firmware we used Marlins' sources, to update the firmware in the future you just need an Arduino board, so you are good to go&#;;)

Support in Marlin Firmware V1 (new)

The basic requirement to add support in the Marlin Firmware is to enable the in the "Configuration.h”. For more details check Marlin's page on how to configure the firmware, see the LCD section.

1. Open the "Configuration.h” file and find the following line:

2. Remove the comment characters "//", so the line now reads:

After build then upload of your firmware to your printers Arduino or mainboard as specified in the firmware documentation.

Caveats

By default Marlin will use the U8G/DOGM libraries to handle the Smart Controller and assume that the LCD driver is the ST

The firmware also offers other define constants for some popular variants of the 'RepRapDiscount Full Graphic Smart Controller', that may use another driver or has a different PIN/layout or other requirement. Look at options under the the "LCD / Controller Selection" sections in the "Configuration.h” file.

To enable the correct LCD in the firmware it is important that you identify if your version of a "Smart Controller" is indeed using the ST driver or if it has a different pin requirement. If that is your situation, then you need to see if the firmware already has support for your version of "Smart Controller" and select it accordingly.

If you have an 8bit board it's likely that it is based on RAMPS, in which case it uses the "pins_RAMPS.h" (or other pins_RAMPxxx.h) as the base of the PIN configuration for your board. You can tell if your board is using a RAMPS as a base configuration by looking for a line similar to near the top. In addition to checking the "pins_XXXX.h" file corresponding to your mainboard, its a good idea to check the base file to see if your smart controller is supported.

Another important aspect of compatibility is dictated by your printers mainboard it self. If you board has a dedicated LCD connector you have to check at minimum two things:

• Ensure that the connector pin-out matches the cable or adapter that you are using. In many instances the supplied cable or adapter is for a particular board.

• Ensure that the pins on the board can actually drive the LCD (connected to a pin that does the required function).

For example a connection that shares the SPI with the an ST LCD will not work and will produce garbage on the LCD. (The ST can not share an SPI/Serial interface).

Issues

• Some versions of this board have the notched connectors the wrong way around. If your controller only flickers and beeps, cut off the notches on the cables and insert them upside down.

• Some clones of this board use really slow LCD displays so their signal timings need adjusted.

The symptoms are that the display gets slightly corrupted. (which can also be cables to long)

In current versions of marlin () add the following to configuration.h to override the default settings.

add "#define ST_DELAY_1 DELAY_NS(0)"

add "#define ST_DELAY_2 DELAY_NS(0)"

add "#define ST_DELAY_3 DELAY_NS(63)" // this is the defaults for a 16mhz processor (ie a mega)

This is used as follows.

For each bit that is sent over SPI

Set the clock pin low and wait ST_DELAY_1

Set the data pin and wait ST_DELAY_2

Set the clock pin high and wait ST_DELAY_3

Slower LCD's seem to need ST_DELAY_3 increased.

Hacks

There are some possible hacks to modify the display.
