help me in IR Remote sensor 8051 code

i hv written the code such a way that by capturing the counter value whenever there is a falling edge pulse after pressing Remote key
while pressing the same key my IR sensor value is changing, what is the problem an di can overcome with that problem???

there is one code which is worked on HCS08 but not working on 8051

Hi friend

First specify, which protocol used in your IR remote.
while pressing the same key my IR sensor value is changing

First change your sensor with same new sensor and used brand new IR remote and check result.
If problem doesn't solve, check your code.

i think, Problem is in your code, not in sensor

Hope this is help you,

i knows there is some problem with that code.......... if possible write the proper code and pass to me
 

Some IR protocols use a toggle bit.

It's purpose is to detect repeat button pressing as opposed to a held down button. Therefore each time you press the same button the code will alternate.

If you get the same different code alternating this is not a problem
you probably just have a code using the toggle bit. You just need to decode
it correctly.

If 3 presses produce 3 different codes - you have a problem.

there is nothing wrong in the remote, there is some problem with that code if possible please change the code
 

First tell us about the protocol of your IR remote,
I worked on RC6 protocol in ccs maybe this will help you if your protocol is also RC6.

i was using NEC i didnt get, then started with capture method by controller
 

Hi friend

I have attached some material for NEC Protocol
I write program for NEC protocol using this material and it work fine.

Hope this is help you

i hv the protocol
that is not working. if u can alter the program means alter it please

i hv written the code by capturing from the PCA and displaying

No its a hardware circuit for interfacing IR reciver and all the protocols have same kind of hardware.
you can judge by the waveforms or by writting the program in microcontroller which will be able to detect all the protocols
