| − | IRTOUCH panel [Android 4.4]
| |
| − | <small>
| |
| − | (1) Download IRTOUCH driver ([[Media:Irtouch-dualtouch-package-android-v14.2.0.0002.7z|Irtouch-dualtouch-package-android-v14.2.0.0002.7z]])
| |
| − | (2) Download IRTOUCH SWAP mode tool ([[Media:Swapmode.7z|Swapmode.7z]])
| |
| − | (3) Swap mode
| |
| − | You need to check and swap IRTOUCH 0X80.
| |
| − | Please install SWAP mode tool in win7.
| |
| − | Run SwapModeTool.exe and choose IRTOUCH 0X80.
| |
| − | (4) Installing the IRTOUCH Dual-touch Touchscreen Driver
| |
| − | (a) irtouchusb-dt.c locate to kernel_imx/driver/input/touchscreen;
| |
| − | (b) modify Makefile in kernel_imx/driver/input/touchscreen
| |
| − | add: "obj-$(CONFIG_TOUCHSCREEN_USBIRTOUCH_DT) += irtouchusb-dt.o"
| |
| − | (c) modify Kconfig in kernel_imx/driver/input/touchscreen
| |
| − | add:
| |
| − | config TOUCHSCREEN_USBIRTOUCH_DT
| |
| − | tristate "IRTOUCH USB Touchscreen Driver For single point"
| |
| − | depends on USB_ARCH_HAS_HCD
| |
| − | select USB
| |
| − | help
| |
| − | Say Y here if you have a IRTOUCH based touchscreen
| |
| − | controller.
| |
| − | If unsure, say N.
| |
| − | To compile this driver as a module, choose M here: the
| |
| − | module will be called irtouch.
| |
| − | (d) You can make menuconfig select TOUCHSCREEN_USBIRTOUCH_DT and build kernel
| |
| − | Modify defconfig CONFIG_TOUCHSCREEN_USBIRTOUCH_DT=y
| |
| − | example : imx6_rsb4410_android_kk44_defconfig
| |
| − | (e) Add one line to Android file system's ueventd.rc:
| |
| − | File path : device/fsl/imx6/etc/ueventd.freescale.rc
| |
| − | /dev/irtouch 0666 root root
| |
| − | (f) Copy "Vendor_6615_Product_0081.idc" and "Vendor_6615_Product_0080.idc" file to the Android file system's /usr/idc directory.
| |
| − | (5) Calibration the Touchscreen
| |
| − | Install CalibrationTools.apk and run "CalibrationTools" to start calibrate touchscreen.
| |
| − | package name:com.irtouch.android.calibration
| |
| − | class name: CalibrationToolsActivity</small>
| |
| − |
| |
| − | eGTouch touch panel [Android 4.2 ~ Android 4.4]
| |
| − | <small>
| |
| − | (1) Add "eGalaxCalibrator" PRODUCK PACKAGES in device/fsl/imx6/iMX6.mk
| |
| − | (2) Add eGtouch file path in device/fsl/imx6/iMX6.mk
| |
| − | device/fsl/common/input/eGTouch_v2.5.2320.A/eGalaxTouch_VirtualDevice.idc:system/usr/idc/eGalaxTouch_VirtualDevice.idc \

| |
| − | device/fsl/common/input/eGTouch_v2.5.2320.A/eGTouchD:system/bin/eGTouchD \
| |
| − | (3) Add eGtouch idc and ini file in device/fsl/imx6/BoardConfigCommon.mK
| |
| − | BOARD_USERDATAIMAGE_PARTITION_SIZE := 128M
| |
| − | device/fsl/common/input/eGTouch_v2.5.2320.A/eGTouchA.ini

| |
| − | device/fsl/common/input/eGTouch_v2.5.2320.A/eGalaxTouch_VirtualDevice.idc
| |
| − | (4) Add service about eGTouch in device/fsl/rsb_4410/init.rc
| |
| − | service eGTouchD /system/bin/eGTouchD
| |
| − | class main
| |
| − | user root
| |
| − | group root
