Comments on: Infrared remote control receiver for Arduino

Hello,
My code actually uses Timer0, so its relevant PWM outputs (OC0A and OC0B, PD6 and PD5 of the ATmega168, J1 pin5 and pin6 of the Arduino NG Diecimila) cannot be used for PWM, just for regular I/O as long as they are kept disconnected from Timer0 (registers TCCR0A, my code takes care of this).
I don’t know what use of Timer2 do other libraries. I may say that it is not easy to know what Arduino’s libraries do with the micro’s resources, one might look at the code, but a sort of heading with the libraries descriptions would be quite helpful for the tweakers.
Hope this helps
Best
Alessandro

Hi Admin
It seems that once we are using this library, pin 3 and 11 cannot be used in PWM anymore
this may be related to the library “tweaking” timer2

do you have any information on that, is it a known “bug” and is there a way to have all PWM outputs work when running irremote library ?

Thank you.
It should work fine with other AVRs. The resources needed are basic and are present on most of them.
Actually it started as code for the ATtiny24 but, silly me, I modified the source when moved to Arduino. I remember very well that the steps needed to do the move where just a few.
If you do the job and intend to publish somewhere, just remember to include the CC license heading !
Ciao

Hello,

I tried this code on an arduino, it work’s like a charm. Thank’s !

I would like to use it with attiny series (attiny 45 or 2313). How can i use it ? did you have some sample code ?

Regard’s

Pierre

THANKS! I’ve been smashing my head against a desk for 3 days trying to get an ATTiny13 to understand any remote codes at all, I’ve modified this one to work!

Again thanks!

As a beginner I spent a lot of time with the rc5 stack from mikrocontroller.net triying to get it to work as an arduino sketch for a “quick” testing the TSOP4138 on Arduino Diecimila
With your script, at first no LED went on, no serial output, “It cannot be that easy”, I thought, the highlight came with the oldest of my three remote controls (for some generic TV). It works! Thanks a lot.

The IR receiver should be fine: to the datasheet your receiver is active low, not high. I mean : when 38kHz IR is received the output goes low. The same logic applies to the IR receivers I tried.
Please read the comments and check if any of them helps you, otherwise please return. At this stage I can’ t help.
Best regards

I’m a real newbie (got my board yesterday ) but already playing with RC5 on my mega board. The code is not working, but I’m not sure if it is due to my IR controller (IRM38bl) which is active high? Only if it receives IR, the pulses make it go low.
