Touchscreen : how to choose?
If I had to choose a touchscreen for my project I rather prefer a capacitive one. Resistive touch screens may be cheaper but have some disadvantages comparing with capacitive ones:


They need calibration
Are less sensitive
Have shorter life cycle


One of the downsides of the capacitive touch screens used to be the complexity of the required software and hardware, but there are already capacitive touch screen display controllers that solve this issue.

Take a look at NHD-5.0-800480TF-ATXI#-CTP from Newhaven Display, it may be what you are looking for.

It includes a controller with I2C interface and it seems fairly simple to use.
