Bitmap2LCD : Working with Custom Color Palettes

Bitmap2LCD is a tool for programming small Graphic LCDs in embedded systems and a programmable graphic and text processing tool.

Working with Custom Color Palettes

From V3.8e , the above functions have been moved to the COLOR PALETTE tab , Main Menu

In the Output + Settings / Main menu, for the color mode range going from 256 to 262k Colors you can load a Custom Color Palette by loading a graphic file (BMP/JPG/PNG) that contains the exact number of reference colors, for example 256 Colors for the Custom 256 colors Palette.

The “Custom Color Palette” will override the “Default Color Palette” in a particular project other than Default.LCD (see below about projects)

To load a custom color palette, just create/switch to a project different than Default.LCD and switch to the correct color mode (for example 256 colors), then click on the “Load a custom Color Palette” item in the Output + Settings main menu (blue arrow). The Color Palette of the Reference Graphic will then be loaded.

The next line in the main menu, below the blue arrow will show you if the Default or the Custom Color Palette has been loaded.

To delete a Custom Color Palette, delete the project name, for example, MyProject.LCD

Getting Started > Basic Settings

  •  In the Output+Settings Main menu, choose one of the the monochrome, grayscale or color depth formats (green frame and arrow)
  • Choose one of the the byte / word output widths : 8, 16 or 32 bit or Intel Hex file output in case of data generated inside the text editor (and text file) or the Binary File Output (output generated in the Hex editor)  (blue arrow)
  • Also Select the endianness, if the most significant bit is left or right in the data output. (red arrow)

bitmap2lcd-basic-settings_1

  • Define the Work Canvas  Size corresponding to the Dot Matrix Size of your Graphic LCD  work-canvas2
  • If the required size is not listed in the Menu ( Width x Height ) use the Define Custom Size item. (purple arrow)

Note : In case of a monochrome GLCD for example, the height or the width might be a multiple of 8 ! It depends of the GLCD : Read the Data Sheet of  the GLCD controller and check the structure and data direction of the pixels in the DDRAM

bitmap2lcd-basic-settings_2

  • Open the Configuration Settings Panel (orange arrow)
  • Define the Data Syntax Parameters and Data output File Extension (red arrow)
  • Define the data direction of the pixels in the Ram of your LCD controller  (blue arrow)

bitmap2lcd-basic-settings_3

  • Change the Output File Header syntax  (green arrow)

bitmap2lcd-basic-settings_4

  • The Output File Header (Blue arrow) is a text file that is optionally copied to the top of the Text Editor when a data array is generated.
  • Edit the Header, then save and Quit the Header Editor (purple arrow)

Note : the words with the [&xxxxx]  syntax are optional script components that are replaced by values by the software. See details at the end of this article

bitmap2lcd-basic-settings_5

  • Export to Data Array to check your settings Start

bitmap2lcd-basic-settings_6

  • Check Data Array Syntax and Format in the Text Editor

Script Components

The script components [&***] can be included only once and will be replaced by the data or value when the data array is generated. Not needed script components can be deleted.

[&NAME]

The [$NAME] and the image size and position are optional and can be placed optionally anywhere in the header.

[&SIZE]

Same for Size of Data

[&TRUEORG]

This is the script component if present in the file, to indicate that you want to have the XPOS and YPOS origins of a reduced dynamic table of constants ( a part of the display you want to change ) given from the X0,Y0 corner you selected in the table translation manager window.

[&XPOS]

[&YPOS]

[&WIDTH]

[&HEIGHT]

The corner position on the Work Canvas and the size of the converted graphic area can be exported into the file.

There are more script components for font generation and data compression.

Reverse engineering : Convert an existing Data Array (or Hex File) to a Bitmap

Update V3.7e , monochrome only

Want to convert 8 bit GLCD data array from an old project to a 16 bit GLCD data array in a new project ?

Want to recover the image from of an old GLCD data array source ?

 

bitmap2lcd-glcd-array-to-bitmap

  • Load a source into Text editor ( Red arrow )  or click on source file inside Text editor
  • Data array inside Text Editor ( Green arrow )
  • Import Data to Graphic  ( Blue Arrow )

For monochrome GLCD data arrays of 8, 16 and 32 bit – bytes/words – , it is possible with bitmap2LCD !

Set your work Canvas Height and Width to a compatible size with the number of data in the array loaded in the text editor, set the byte word  Width to 8 16 or 32bits (in the output main menu) , select the data direction (horizontal or vertical) and click one of the import Data Array buttons. If it matches with the data count, the Work Canvas will show the graphic.

For example in a file an array of 2560 bytes ( 0x00 – 0xFF )

( Width * Height ) Pixels per byte =  (160 * 128) / 8 = 2560 bytes

Import the array into the work canvas and save the work canvas as bitmap.

Import System Chars into the Font Editor

Bitmap2LCD is a tool for programming small Graphic LCDs in embedded systems.

Import System Chars into the Font Editor

Update V3.7e , Standard Edition

bitmap2lcd-glcd-font-menu

Let’s see how we can export selected characters out of a Windows System font into the Font Editor of Bitmap2LCD :

  • Create a GLCD Font Script by clicking the Main menu item or the Font Panel Button (blue arrow)
  • Choose a Font Name and define its size

bitmap2lcd-editable-font_1

  • In the “Ascii Grid“, select the chars you want to export, here for example A, B and C  (red arrow)
  • In the menu, click on item ” Start editable font Export > Editable (Translate LCD Font Script to an Editable Font (green arrow)

bitmap2lcd-editable-font_2

The “editable font” has been created. It is an Editable Font File (EFF) and an associated GIF file, which is the catalogue of char bitmaps. Both files are located in the Fonts folder.

  • Quit Font Script Creator mode and Open editable (orange Arrow)

bitmap2lcd-editable-font_3

In this example, the selected font name and font size were Aria Unicode MS and 20, in this case the filename of the file will be Arial Unicode MS_20Editable_Font.EFF

bitmap2lcd-editable-font_4

The patterns of theses 3 chars (green Arrow) can now be freely edited.

Example 2

In the first example above, the height of the chars is 25 pixels.

This time, we want to limit the Size of chars in Height and in Width and export a Fixed Size Font.

  • Change the first 3 Parameters (purple arrow) and you will see a red frame in the char View (green arrow)
  • Export To editable (blue arrow)

bitmap2lcd-editable-font_5

  • You get these editable chars
