I want to make a touch panel which sends command to a uc. I have searched but do not know what to use. I found a 4-wire resistive touch screen by the size of 240*128 but have to combine it with a graphical lcd. Is it the logical way? BTW, what is the size of the screen 240*128 in inches?
I also found that there are some chips which make it easy to interface with the touch screen such as AD7877 and AD7873. Are they necessary for controlling the touch screen.
There is a chip SSD1963 and was wondering if I could use it for touch screen?
