Bitmap to GLCD Hex file >> Output settings

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

Go to the Main Settings (v2.5 +):

bitmap2lcd settings

From V2.5, the below settings can also be found on the file explorer window, outputs tab : there’s a button at the top right to hide or show this toolbar.

Bitmap2LCD is a universal programming tool for converting bitmaps/images to GLCD for most graphic LCD controllers. (Monochrome,Grayscale, and Color ->[Color from V2.0] )

The software converts the bitmap and generates a hexadecimal file according to the previously defined user settings.

Here’s a short description of the available settings :

The hexadecimal output format can be selected with a series of buttons located in the output panel (fig 1.)

Description of the settings:

  • The choice of 8 different vertical or horizontal pagings ( the buttons with the arrows ) , your choice depends of the GLCD controller which is built in your LCD module. ( Please refer to the GLCD controller datasheet )
  • Most significant bit is first or is last (Data bit 7) — or in other words the data endianness.
  • Byte nibble swap On/Off, for example for 16 gray level grayscale mode for Sitronix ST7528 controller compatibility. ( In the case of 2 pixel per data byte, 4 bit per pixel data, gray levels )
  • Negative or positive output setting
  • GLCD zero corner selection (Corner where the conversion starts)
  • Output File Header Editor , (A small script to configure Hex file header)
  • Enable/Disable of the Output Data for compression for monochrome GLCD.
  • Enable/Disable 6 or 8 bit Data byte wide output for T693C Controller

As the converted output can just contain a part of the display size, there are other selectable options (not on fig1.)

  • Enable/disable X,Y area coordinate data insertion in the Hex ouptut file
  • Enable/disable area size data insertion in the Hex output file

These configuration settings are saved when you quit the application and restored on application launch. These settings are also a part of the project specific configuration.
