Using LEDs, LCDs and GLCDs in Microcontroller Projects

12.9 Summary

This chapter has described the design of microcontroller based projects using GLCDs. At the beginning of the chapter, the creation and displaying of bitmap images are explained. It is shown how easy it is to create a bitmap image using the Windows Paint program. Then, a simple animation program is given, where a ball moves across the screen inside a rectangle shape. More complex projects, such as a GLCD dice, and the plotting of X-Y graphics, are given in later sections. The measurement and display of temperature is then given as a project, where the temperature is plotted on the GLCD screen. Finally, a project is given, where the ambient temperature and relative humidity are measured and displayed on the GLCD screen.
