Mikroelektronika Glcd Bitmap Editor

Discription :

n the first part of this tutorial, we discussed about Winstar’s WDG0151-TMI GLCD module, which is a 128×64 pixel monochromatic display built with KS0108B and KS0107B compatible display controllers. The module was interfaced to a PIC16F887 microcontroller and a test program was written in C to demonstrate how to implement the KS0108 instruction set in the firmware of PIC to activate display pixels on the screen. We wrote our subroutine programs that would turn the GLCD on, move the display location to a specified row and column, and draw a pixel at a given coordinates. You might have realized it by now that how much of effort is required to write the firmware for just plotting a point on a GLCD screen. Today’s discussion will focus more on using the built-in GLCD library routines of mikroC Pro for PIC compiler, which will make your life a lot easier if you are using a graphical LCD in your project.

GLCD Library of mikroC Pro for PIC

Choose a Font Generation program that produces Fonts in the format used by your library. Or just say which library / format you are using. Someone will post an 8-pixel and a 10-pixel Arial Font for you. In fact, I would expect your library to provide at least one Font by default. LCD Bitmap Converter for eGUI is an image converter tool, which helps you conveniently convert any images into a Microchip Library bitmap, which can be easily integrated into your Microchip Library based project How to use mikroElektronika's GLCD bitmap editor tool to convert a BMP image in to a data array Posted on October 24, 2011 by R-B 6. GLCD Font Creator enables the creation of personalized fonts, symbols and icons for LCDs and GLCDs. Create fonts and symbols from scratch, or by importing existing fonts on your system. It lets you modify and adjust them for your needs, apply effects and finally export them as source code for use in mikroC, mikroBasic or mikroPascal compilers. Choose the main menu GLCD Fonts tab, and click Enter Font Script Mode item to enter Font Creation Mode. Data Setting Parameters are located in Data tab. You can edit the values by clicking on parameter value of the parameter list, only when in Font Script Mode and with Standard Edition. At the top of the font panel, the caption includes Font.

The mikroC Pro for PIC provides GLCD library for a 128×64 pixel graphical LCD with Samsung KS0108/KS0107 controller chips. The library routines are categorized into two types: basic andadvanced. Before using any library routine, following pin definitions is required. For our case (see the circuit diagram in the first part) where PORTD is used for data and PORTB pins for control signals, the GLCD pin settings should be defined as follows. Remember that the data lines must be on a single port.
  • Glcd_Init : Initializes the Glcd module
  • Glcd_Set_Side: Selects the Glcd side. Example, Glcd_Set_Side(0) and Glcd_Set_Side(62)both select the left side of the GLCD. Values from 64-127, such as Glcd_Set_Side(67), selects the right side of the GLCD.
  • Glcd_Set_X : Sets x-axis position from the left border of Glcd within the selected side. Example, Glcd_Set_X(25).
  • Glcd_Set_Page : Selects page (0-7) of the Glcd.
  • Glcd_Read_Data : Reads one byte of data from the current location of Glcd memory and moves to the next location.
  • Glcd_Write_Data : Writes one byte of data from the current location of Glcd memory and moves to the next location.
Advanced routines:
  • Glcd_Fill : Fills GLCD display RAM with a byte pattern. If the byte is 0, it will clear the display. If it is 0xFF, then it will fill the entire display with 1.
  • Glcd_Dot : Draws a dot on Glcd at given coordinates with a specified color. It is used asGlcd_Dot(x, y, color), where x = 0-127, and y=0-63, and color = 0-2. The parameter colordetermines a dot state: 0 clears dot, 1 puts a dot, and 2 inverts the dot state.
  • Glcd_Line : Draws a line joining two specified point coordinates and a given color value (0-2).
  • Glcd_V_Line : Draws a vertical line passing through two points with the same x-coordinate. It also accepts color parameter.
  • Glcd_H_Line : Draws a horizontal line passing through two points with the same y-coordinate. It also accepts color parameter.
  • Glcd_Rectangle : Draws a rectangle with specified top left and bottom right corner coordinates. It also accepts color parameter.
  • Glcd_Box : Draws a box with specified top left and bottom right corner coordinates. Unlike in Glcd_Rectangle, the color parameter here is the fill color of the box.
  • Glcd_Circle : Draws a circle with specified center coordinates and radius. It also accepts color parameter.
  • Glcd_Set_Font: As it was mentioned earlier in Part1, KS0108 controller does not have a built-in character generator and therefore fonts must be written in the firmware of the external microcontroller. This is a time consuming task as you need to determine data values for each letter to display. For simplicity, mikroElektronika provides the following demo fonts with mikroC Pro for PIC compiler.
    • Font_Glcd_System3x5
    • Font_Glcd_System5x7
    • Font_Glcd_5x7
    • Font_Glcd_Character8x7
    These fonts are used by Glcd_Write_Char and Glcd_Write_Text functions (defined below) to display character and text. The syntax for defining font is,
Glcd_Set_Font (const char *activeFont, unsigned short aFontWidth, unsigned shortaFontHeight, unsigned int aFontOffs);

  • activeFont: font to be set. Needs to be formatted as an array of char
  • aFontWidth: width of the font characters in dots.
  • aFontHeight: height of the font characters in dots.
  • aFontOffs: number that represents difference between the mikroC PRO for PIC character set and regular ASCII set. Demo fonts supplied with the library have an offset of 32.
So, if you want to use the Font_Glcd_5x7, you can define the font as,
  • Glcd_Write_Char : Writes a character at a defined x-position (0-127) and page number (0-7) on GLCD.
  • Glcd_Write_Text : For printing a text at a given x-position (0-127) and page number (0-7) on GLCD
  • Glcd_Image: Displays bitmap image on Glcd. The bitmap array of the image must be provided in the firmware. I have described this part in more detail in this post:

    How to use mikroElektronika’s GLCD bitmap editor tool to convert a BMP image in to a data array

It is the same as described in Part 1 of this tutorial and I am using UNI-DS6 development board for demonstration.
The following program is written in mikroC Pro for PIC compiler for demonstrating the GLCD library routines described above. The first part of the program draws horizontal and vertical lines, rectangle, circle, and a filled box on the GLCD. The second part writes texts in all eight pages (0-7) using Font_Glcd_5x7. At the end, bigger font size (Font_Glcd_Characters_8x7) is used to write “Embedded Lab” at the center of the screen.
The pictures below show some of the outputs of this program. This has been tested on UNI-DS6 development board with PIC16F887 microcontroller.

You can also display a 128×64 pixels monochromatic bitmap image on the GLCD. For this you need to first convert the bitmap image file into a data array. The following link takes you to a tutorial page which describes how to do that.
