13.3 Summary

Touch screen GLCDs are used in many consumer and industrial control applications. Most electronic games, mobile phones, MP3 players, GPS systems, and so on all use the touch screen technology. This chapter has explained the use of touch panel screens in microcontroller based projects. Two tested and working projects are given in the chapter. The first project is simple and shows how to control an LCD using two shapes on a touch screen LCD. The second project shows how to change the flashing rate of an LED using touch screen GLCD, where the flashing rate is selected by touching appropriate boxes on the screen.
