| Summary: | 碩士 === 國立成功大學 === 微電子工程研究所碩博士班 === 91 === A set of touch panel consists three main parts:
(a) Sensor
(b) Controller
(c) Software
The object of this thesis is to realize a set of touch panel. And we will focus on the parts of the controller and the software, as for the part of panel (sensor), we use the product of CHILIN TECHNOLOGY CO.,LTD.
The main specifications of our touch panel are:
(a) 4-wire resistance touch panel
(b) USB interface
Because the interface of our device is USB, we use the Cypress Semiconductor Corporation’s production:
CYDB Debugger/CY3654 Development Kit
to emulate the USB microcontrollers.
The signals got from the touch panel are analog, so we must use an ADC to convert the analog signals to digital signals. The ADC we use is ADC0804.
The touch panel needs switches to switch the energized direction. On this part, we choose PC817 series and BJTs to play the role of switches.
In regard to the software we select Visual Basic to write our program.
