Chapter 13

Touch Screen Graphics LCD Projects

In this chapter we will look at the design of projects using graphics LCDs (GLCDs) with touch screen panels. As in Chapter 12, the GLCDs used in the projects in this section are 128 × 64 pixel monochrome, 78 × 70 × 14.3 mm displays, based on the KS108/KS107 controller. A 4-wire resistive touch screen (model no: TTW4028001) is used in the projects. Two projects are given in this chapter. The first project is simple and shows how the touch screen can be utilised to turn an LED ON and OFF. The second project is more complicated and shows how to flash an LED at a rate chosen by the user by touching the screen.
