My "sig" (signature) is my big name in the upper left of my posts. Click it for "Renate's homepage". You could install UsbMode.apk directly from there, I never think of that. I use ADB for everything. UsbMode.apk shows at the bottom line any screen touches.
ADB is the USB debugging connection. It's something useful to learn. I won't go through the details because there are a zillion tutorials online, Google "install minimal ADB".
Code:
C:\>adb shell <-- We're typing to the Windows command line
$ su <-- We're typing to the Android shell (over ADB)
# <-- We're typing to the Android *rooted* shell (over ADB)
If you have ADB working you can do a command like this:
Code:
$ cat /dev/input/event1
��{a89��{a85���{a86���{a8J��{a8��{a9������{aJ��{a
That's looking at the touch screen. It's quiet until I poke it with a finger then a binary blob spits out, like it should.
