Resistive touch screen datas

[pnsuresh]

Hi,

Am connecting 4 wire resistive touch panel to arduino uno board. (Am using TouchScreen.h library)

pressure is always zero. I need to know 4 wire resistive touch wire connection.

Intended connection is explained in the demo project

#define YP A2  // must be an analog pin, use "An" notation!
 
#define XM A3  // must be an analog pin, use "An" notation!
 
#define YM 8   // can be a digital pin
 
#define XP 9   // can be a digital pin

How to identify in Touchscreen(ST-008) connector?

 

[FvM]

Datasheet or ohmmeter.

Am using 15 inch resistive touch screen. 1 and 3 resistance value is 530 ohms (Y+ , Y-)
2 and 4 resistance value is 300 ohms (X+ , X-)

 

[pnsuresh]

1 and 3 resistance value is 530 ohms (Y+ , Y-)
2 and 4 resistance value is 300 ohms (X+ , X-)

This pin numbers are correct or not? Touch screen model - ST-151001 (ST-008)

Hi,

Just follow the traces ... it's quite obvious.
(I don't have one by hand, to do this for you)

It's not showing correct value. Pressure =0.
