IRremote Library Not Working

[CptSky 0]

Hello,

I'm using IRremote library and IRrecvDemo is working perfectly, however IRsendDemo is not working. I've commented out these lines in IRremote.cpp

//pinMode(TIMER_PWM_PIN, OUTPUT);
//digitalWrite(TIMER_PWM_PIN, LOW); // When not sending PWM, we want it low

and removed the if (Serial.read() != -1) condition, but it is still not working. Do you have any idea what might be the problem?

Thanks.

Protocol mismatch? Wrong modulation frequency? Hardware problem? Use a mobile phone camera to see if there is any activity out of the IR diode,  assuming you are using one for transmission.

There is no output at pin P2_3, that’s the problem. Literally nothing happens. I debugged it and it enters the for loop but sends nothing.

Hi @CptSky

You haven't provided much information - no code really, no information on the microcontroller, the pins used and how they are connected, etc.

If you have commented out code as described in your first post then of course there will be no output if  TIMER_PWM_PIN is P2_3.

//pinMode(TIMER_PWM_PIN, OUTPUT);
//digitalWrite(TIMER_PWM_PIN, LOW); // When not sending PWM, we want it low 

I don't think it is possible to give meaningful help without more information.
