16. You can enable the touchscreen by modifying the configuration
|

in the following ways:
|

|

System Type:
|

CONFIG_SAMA5_ADC=y : ADC support is required
|

CONFIG_SAMA5_TSD=y : Enabled touchcreen device support
|

SAMA5_TSD_4WIRE=y : 4-Wire interface with pressure

You might want to tinker with the SWAPXY and THRESHX and THRESHY
|

settings to get the result that you want.

CONFIG_INPUT=y : (automatically selected)

Board Selection:

CONFIG_SAMA5_TSD_DEVMINOR=0 : Register as /dev/input0
|

|
||||
Library Support:
|
||||
CONFIG_SCHED_WORKQUEUE=y : Work queue support required
|
||||
|

These options may also be applied to enable a built-in touchscreen

Applicaton Configuration:
