IRremote

[misterhay 0]

Has anyone been able to get the IRsend demo (or anything else related to IRremote) to compile in Energia?

[energia 484]

IRremote library with all it's examples is included in Energia 0101E0008. The receive examples have been tested and should work for you. Due to lack of test hardware we were not able to test the send demo's.

Is there anything in particular that you would like to test it with.. I can send that over provided it is under $10.

I have some IR stuff in my parts bin as well. List what you need and it will probably get filled pretty quickly.

Thanks for the offer guys. Really appreciate it! I won't be able to get to it for a while though due to work on FraunchPad support. Hopefully somebody in the community will test it and let us know if there are any issues with it.

IRsendDemo working example (energia-0101E0009)?

IR LED connected to P2.3 but nothing happens  :?

 

IRrecvDump - works without problems (via TSOP4836)

 

MCU - g2553

Any ideas, what is wrong?

hi has anyone had any luck with the IRsend demo?
i am getting an output at pin 1.2, but no data is being sent, and nothing happens at pin2.3(which pin should the output be connected to?). 
i am using 2 launchpads, the IRrecv demo works fine.
ran the IRsend demo on an arduino and it works fine there.

You need to modify IRremote.cpp under "\hardware\msp430\libraries\IRremote".

After the TIMER_PIN_SELECT();

Comment these lines :

 

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

 

The pin output is P2_3. For the demo you need to send something on serial to transmit.

 

PS: Tested and working IRrecv and IRsend with 2xmsp430g2553.

 

Hope it helps,

Have fun

thanks a lot PowerX.. works perfectly...

just wanted to know if it is possible to send and receive at the same time.

ie.. use the IRremote library for transmitter-receiver pair on the same launchpad so that it can detect its own signals. 

possible application would be obstacle detection.. 

thanks

I don`t exactly understand your question but you can make a transceiver between 2 microcontrollers. I dont know why would you want to transmit and receive at the same time data on the same uC it is like if (1==1) loop, if you want to use ir for sensing you can use adc ex: a photoresistor or phototransistor and a ir led.

there are many tasks where it is needed, such as learning remote control, IR extender, RX/TX data via IR etc.

I also did not work at the same time send and receive (because Send and Receive both share the same timer).

 

P.S. for testing IR I'm using PDA with Irda and software NR DELUX - highly recommend! and a mobile phone with a camera of course  ;-)

hi all : 

 

I try to modify the main loop to make send and receive function, but why i send any data from UART?the P2.3 will make 9.8kHz frequence?

 

 

void loop()

{

  if (irrecv.decode(&results))

  {

    Serial.println(results.value, HEX);

    dump(&results);

    irrecv.resume(); // Receive the next value

  }

  else if(Serial.read() != -1)

  {

    for (int i = 0; i < 3; i++) 

    {

      irsend.sendSony(0xa90, 12); // Sony TV power code

      delay(100);

    }

    irrecv.enableIRIn();

  }

}

 

I find root cause, must disable P2.3 Timer output function.

 

P2SEL &=~BIT3;

After a long hiatus I came back to it and it worked. I realized that that the issues was probably that I was trying to compile for the 2231 and running out of space. My code is at https://github.com/misterhay/IR-Power-Buttons-for-Projectors/blob/master/TBC_Projector_Remotes/TBC_Projector_Remotes.ino

 if anyone is interested.
