3.8 Touch Screen

A key feature of the CB3052 is the possibility to connect a touch screen. Both 4-wire and 5-wire resistive

touch screens are supported. For receiving the relevant signals a 5 pin standard IDC socket connector

with a spacing of 2.54 mm is provided. If the connected touch screen is 4-wire then pin 1 will not be used.

Next to this connector is a jumper which, if shorted at boot time, triggers the NVRST-signal in the

controller, thereby resetting all parameters of NVRAM to default values.

Conversion to the respective connector of the touch screen must be provided externally. Please consult

the manufacturer’s documentation to figure out the relevant technical details.

Note: In the pinout table below H, X, S, Y, and L are the signal names in the case of 5-wire, XL, XR, YT,

and YB are the names in the case of 4-wire.
