TouchPanel Controller manual All Mikroelektronika s development systems feature a large number of peripheral modules expanding microcontroller s range of application and making the process of program testing easier In addition to these modules it is also possible to use numerous additional modules linked to the development system through the I O port connectors Some of these additional modules can operate as stand alone devices without being connected to the microcontroller 7 MikroElektronika SOFTWARE AND HARDWARE SOLUTIONS FOR EMBEDDED WORLD waking ib siw ple TouchPanel Controller The TouchPanel Controller additional board is used to connect a touch panel to a development system Key features Connection established an IDC10 connector Low power consumption and 3 3V or 5V power supply voltage Figure 1 TouchPanel Controller additional board How to connect the board The TouchPanel Controller additional board can be easily connected to a development system via an IDC10 connector CN1 that is connected to a port of the development system Connection between the additional board and a touch panel is established via the CN2 connector provided on the additional board How to use the board A touch panel is a transparent touch sensitive foil In order to register any touch it is necessary to connect the touch panel to this additional board The principle of the touch panel operatio
3. n is based on the voltage change caused by a touch or pressure applied to the touch screen Voltage change detection is enabled due to the touch screen design It is composed of two flexible sheets coated with a resistive material separated by an air gap In order to detect a contact it is necessary to apply voltage to one of these two sheets DRIVEA for example When contact is made the two sheets are pressed together and the second sheet measures the voltage in the pressed point as a distance along the first sheet The measured distance is referred to as X axis BOTTOM As soon as this data is aquired the same voltage is applied to the second sheet DRIVEB Now the first sheet measures the distance referred to as Y axis LEFT Here you can find examples for the TouchScreen Controller board http www mikroe com eng products view 184 touchpanel controller board MikroElektronika BOTTOM DRIVEA VCC Figure 2 TouchPanel Controller board connection schematic 35 05mm TOUCHPANEL CONTROLLER HWREV 1 10 3 20mm 22 2m BC m ws 2E 020 29 63 Figure 3 Dimensions of the additional board MikroElektronika aouu mmm B SN JOU sjesodosd sse uisng 10
