hi
i built tth project RC5 code IR remote control provided by ajay . circuit is working fine with pressing buton no 3,4,5,6,7,8 and power . but it is not responding with 1,2,3
please help me out i have gone through codes (well i am still learning) but i really not understand why it is not working i have used phillips companey remote and codes are working same with TSOP1738 and TSOP1736 please help me ou t

thats really a strange problem. Well debugging this ip little difficult but if you con do it will be good for you. After command and data is extracted, display it on hyper terminal you need to make changes in program to display the values on pc. Thats the only way to check whats the real problem. You need to tell me what you get when you press 123 on remote.

wel ajay i am talking about 'IR Remote Switch using TV remote (RC5 Protocol)' project

hai sir

sir i want to do project on ir remote
i have seen ur code for rc-5,but iam not understanding the how u have calculated the delay.it ia not giving the 1.728ms delay.please help me. and which remote should i use ??

sunrom i know which project you are talkin about, but what we are talkin here is debugging your problem so the only way to debug it is.. to find out the o/p you are getting from IR receiver. To check that o/p we need to display it somewhere so serial can be one way.. second could be LCD, third is LED on a port so whichever you feel better you can chose.

Could you please add a circuit to make it serial or to use with LCD or LED!

Can anyone help on this?

serial circuit is already there.. all you need to do is simply extract the three important things, address, command and flip bit and display it.. and check it on serial window after you press the button, so you can check whether you are getting the right value or not.

Dear Ajay, My hand is really tight in assembly as I am an IT pro, and the code attached with the project is written in Assembly. Can you please do me one favor, either rewrite the code in C or add few procedures in the existing assembly code to display the address, command and flip to the attached 2 line LCD terminal.

Hope it won't be that difficult for you

obviously its not difficult... but! i am short of time...

Then whenever you have time....

Hello say2paul,

here is my code which i use to read the Address and command values sent by a RC5 remote. Address is displayed on 1st line and command on 2nd line. both are displayed in decimal. its in asm but you can use it for debugging

hope you'll find it useful !

forgot to mention the code is for 8051 running @12 Mhz
