Capacitive v resistive touch panels
-----------------------------------
Embedded Linux with capacitive and resistive touch panels have exploded with the arrival of Android and ARM processors.
But which one to go for?
Go capacitive!
The older resistive touch technology require calibration, is prone to wear and degrades more quickly than capacitive touch panels.
Also with capacitive touch panels, you don't need to physically contact the surface to get registration, which also means prolonging life.
The drivers for capacitive and resistive sensors are more or less same. An RS232 like stream of data is sent by the chip and it locates the X and Y position of touch. It can't get any simpler if you are writing drivers or hacking existing machines.
