I am absolutly dilettante in this discipline but I have some questions. I try to send IR code to TV over Arduino UNO. I try to change something small in demo routine becouse I can not get all informations to write the routine. The program but give the most of errors yet about java instructions though I open it in intact version. Is some code under the text of routine that is invisible but present? Now I install whole IDE as new. Why can´t I find some function routines or some concomitant text about problematics? For example how I can detect the remote controler frequency and so on.
Welcome to the forum
Start by posting your sketch, using code tags when you do, and the full error message, again using code tags, along with details of what you have connected to the Arduino
Which version of the IDE are you using ?
What library are you using? The latest version is pretty comprehensive if you go through the examples.
Super the code to TV sended. Other is the common scrapes solvable by rewriting the program into my clean project.
I used the IRremote.h and IrSendDemo example.
Thanks for the messages.
I see that I give only small time to project.
If I rewrite code from demo file compilation test still gives errors. I reinstalled IDE but the libraries and settigs of files still stays set on old instalation. I´m sure that errors are in IDE and know not why can´t uninstall completely. There are some problems with administration of libraries. Some new advices for me?
Thanks.
very bold statement 
Please show your edited code and compilator error messages
