NHD‐3.5‐320240MF‐ATXL#‐T‐1 Touch Signal
« on: February 04, 2016, 07:36:18 PM »
The NHD‐3.5‐320240MF‐ATXL#‐T‐1 display has a 4-wire resistive touch panel. Is this similar to the industry standard ADS7843?

If so, what is the mapping between the Y1, X1, Y2, and X2 signals to the standard X+, Y+, X-, and Y- standard signals?

Can a driver for the Texas Instruments ADS7846 touch screen controller work on this display?

Morning jmasamoto,

The mapping is as follows:

Y1 = Y+ or YU
Y2 = Y- or YD
X1 = X- or XL
X2 = X+ or XR

I personally have not used the TI ADS7846, however after looking over the datasheet it looks compatible  8)

Hope this helps!
