May I know how can I invert my IR output signal using IRsend, i.e. 0->1 and vice versa.
I'm making a infrared intercept module on top of my IR repeater so that only the IR codes of few specific but not all devices are feeded from my bed room to sitting room.
Pls read its configuration:

I've successfully built it. The module was able to redirect IR codes and transmit thru a IR LED. We directly feed the IR codes to another IR receiver circuit instead of thru IR LED, the module become not work. I learnt that I must invert the output level. I've tried negate the send codes before passing to IRsend but it does not work. I finally add an external negation circuit using a NPN transitor to invert the output. The circuit become works but not reliable. The successful rate dropped to abt 30%. I think it will be much better if I invert the ouptut within Ken's library. Please kindly help
