hai sandeep can you please tell the remote you used.am just started with the projects.what all problems did you faced.how did you solved it.can you tell me what to do once the library functions worked well?what is the next step.this is 1st project with a controller.me at ground zero.can you share your knowledge please

I’m sorry but what is “6th standard”?

“BTW I want to change the display code to HEX, any idea to convert it to HEX before being displayed on LCD?”

Pal those things are taught in 6th standard!

Hi Avinash,

I finally got it working…thank you so much for posting such a great tutorial…

@Halfgaar

I wrote the lib many years back when I was new in this field. So their may be many faults (but NOT bugs).

I still use the lib in many projects but never required any modification to the actual lib.

Hi,

I’m trying to re-implement your lib to learn and to suit my slightly different needs. Anyway, I found a few things that may be helpful.

I think there is a bug in the Atmega8 driver, and perhaps others:

In the INT1 interrupt handler, you set TCNT0=0, but you’re using timer1. You should set TCNT1=0, right? Plus, TCNT[1|0] are 16 bit registers, which need special care to write to (interrupts need to be disabled while you do it).

Then, about the clockspeeds, why don’t you just do:

#define TIMER_INTERRUPT_AFTER_US (10)
#define us_to_timer_compare_match(time) ((F_CPU/1000000)*time)

Then set OCR1A=us_to_timer_compare_match(TIMER_INTERRUPT_AFTER_US)

I do and it works great.

Hi Avinash,
Thank you for this wonderful tutorial. I would like to use the internal 1MHz default oscillator. Is it possible to use this or should I have to use the external 8/12/16 MHz compulsorily?
Thank you
Dinesh

Just for the information of everyone, I used a BPL remote version RC1088N….and Car mp3 remote….

@Avinash: I forgot to mention I had to change the code at 3 places in the code remote.c. All were changing “char” to “int”. I made change for Qfront,Qend and i (occurs in ResetIR() and RemoteInit() )….thanx once again for your help…:)

Thanq so much….the code works superbly….thanx once again….:)

hi Avinash,

I am using a c program in the microcontroller, but i have a problem regarding about how to add an interrupts to my program. It is about this that when i will send a signal from a remote contol it will bypass all the running programs and make priority to the signal fom the remote control.. Please help me with this one… thanks!
I can send you all the necessary info regarding with this. Again Thanks!
