i am buliding a touch screen (4 wire resistive) for my final year project in university. and i need some help to point me in the right directions.
i now understand they are 3 parts to the project
1. building of the touch screen itself
2. creating a controller for it
3. the software interfacing
my problem is as follows
for the first part (building of the touch screen itself)
i know i need ITO coating on a glass or some sort of plastic
does anyone know where i could order this somewhere in the uk?
2. should get the coating with the most resistance?
3. i am going to have problem with noise either form the lcd screen i am mounting on or the plate itself and how do i resolve this?
for the second part (creating a controller for it)
any idea for a cheap 4 wire controller or chip to be used to make this controller to work through the RS232 port?
please any schematics?
for the software part
how do i get it to actually move the mouse in windows xp.
and do i need to create a driver?
any help you give me is appreciated and thank you for taking time to read my request.
