I will try and keep this brief. I am “working” on trying to get the sidelights on a custom 10″ android display with sidelights (for meeting signage) to work.

I am just starting to try and follow the instructions the manufacturer gave me (pasted all that below). I seem to need a file called LibledsetJni.so

Anyway! I connect to the panel using adb shell in root. If I am in root and I search like this:

root@rk312x:/ # ls -laR | grep (and either) “libledsetJni.so”, or “ledsetJni”
it comes up with -rwxr-xr-x system system 13432 1979-12-31 11:42 libledsetJni.so

WHich makes me think this file is somewhere. However I cant find the path. If I go up from root to system and do the search again, it comes back with nothing. I have been working on this for over a day and I can’t find this file anywhere!! Can someone please help?

Thanks

Instructions from manufacturer on getting lights to work.

Controlling LED JNI User Guide There are two ways to import the JNI : 1) Directly use our JNI, copy the Libledset.Jei.so file into libs\armeab, use the below codeand load the lib document. public native void setLedState(int led, int state);static{System.loadLibrary(“ledsetJni”);} Reminders: In System.loadLibrary(“ledsetJni”) should use ledsetJni and not libledsetJni.so Library document name should be: com.glorystar.ledtest, category name is: MainActivity. The set I/O use setLedState (int led, int state); led is 0 setting red, led = 1 setting green, state= 1 open, state=0close

2) Rewrite the JNI document. Put the reference JNI document copy to the project, note to revise theJava_com_glorystar_ledtest_MainActivity_setLedState in ledset.c . Use your own projectname and category name for exchange, NDK programming should be self- learnt, themethod is on number 1.
