Nice work, but i didn't see acknowledge LED as response indicator on circuit...
I try to compile the code file, but there is some error.
What compiler u suggest? i use Reads 51 V4.20.
Or u can post hex file.
Thanks..

Respected Ajay Sir,

My self Sharad Chandra Sharma ,sir I have read the IR remote switch source code from internet it is an excellent effort yet I m confused by two type problem both are inlisted below . Please try to solve it I will be very thankful to you.

PROBLEM-1
In the software program of Phillips RC5 decoding (a 8-switch control asm code) , I have great confusion in reading the IR bits along with the time delay .I have explain my problem in details

Sir under the main lable after giving the 3.024ms a delay is given for AGC bits, after then the IR data is moved to carry bit (for reading the flip bit ) and further stored in FLIP location.

Under fadd lable the first 1.728ms delay is given then IR is moved to carry bit and further rotated into Accumulator , and DJNZ COUNT,fadd loop runs .

Sir my question is that way do you not given the delay for ‘FLIP bit or TOGGLE bit’ also under the fcmd lable initially 1.728ms delay is given and then command bit is readed way !
Or in other words we an say that
….moving the ‘flip bit’ into carry bit and further stored in FLIP location , DOSEN’T need time delay.

PROBLEM-2
In the same software for creating the software loop delay you have loaded a value in variable 1, mov VAR1,#255 ,sir what is the formula used for creating the 1.728ms delay.

Ajay Bhargav | 15 Oct : 00:50 Hi sharad, This is the comment area so you cannot post your problems here. Please post them in the forum. See the link at top navigation... And just to get started.. there is no specific formula to calculate the time delay.. you need to calibrate it.. using experimentation. You can find the exact delay generated by the loop using the number of machine cycles needed to execute that loop multiplied by the timer per machine cycle. Check forum for a better explanation Reply to this

Sharad chandra | 15 Oct : 23:02 Sorry Ajay sir for posting the problem on worng area yet i already emailed the same problem on - contact@rickeyworld.info. Respected Ajay sir Can i have your contact number along with contact time. Plz DONT Say NO...... You can Email me at- hind_sharad@yahoo.co.in Reply to this

"If you need information on RC5 protocol them visit the link below".......spelling mistake.... it should be "If you need information on RC5 protocol then visit the link below".......lol...

sir iam not undersdtanding how u have calculated the delay..
sit the machine cycles for djnz are 2,if i consider this iam not getting the 1.728ms delay for ur code.
please help me as soon as possible..

Sir, plz send me the remote number which uses the RC5 code.

I not able get TSOP 1736 IR Receiver in the market, instead can I use TSOP 1738. Due to the change in the frequencyof the IR Receiver,do we need to change the code.
Great project"""""
Reply to this  

Ajay Bhargav | 07 Jul : 10:57 code will not work with TSOP1738 as remote works on 36 khz. Go to any repair shot and ask for Philips tv remote receiver they will give you dont go for technical stuff.. when you deal with repair people. Reply to this

sir i am using th the phips modal rc1153014 having protocol rc5.
time delay is 1.72 micro sec. for 1.72 delay remote data is no recive on micro. 89c51 port having 11.0592 Mhz oscilltor.ir reciver recive the data properly.

how much delay use to to recive the data properly is 1.78 or other delay.
kindly guide me as the urgent matter

Sir,
Can I use 89S52 instead of 2051. Does it need any modification? Can you Please give the keil C code for it.

Ajay Bhargav | 30 Aug : 14:47 no there is no change, just keep same pins. Reply to this

Hello Sir,
This project is quit impressive to me. I was thinking that if no one has this remote control then how he could switch on/off the electrical appliances. So for that i was thinking that why don't you make own remote control based on 8051. Actually I tried a-lot but failed. I don't know what happened. I'm new in this field. So for this project I need your help. Will you help, Please?

Thanks & regards
Abhinav

Hello Ajay sir i just want to thank you for giving such a nice project!!!!!
i have completed this project in very small time !!!
and it is working great !!!!!! working with Rc7805 remote any IR sensor having 36Khz or 38Khz....but according to my observation ...if i use 36Khz receiver then range extends,,& believe me it does not requires to point remote at the sensor,,,,devices can be operated by pointing remote anywhere,just like RF !!!!!
So i am very happy to thank you !!!!!!

now i am going to increase the number of devices ,,above 15...
i have done with programming !!!!now going to test that !!!!
if necessary i will use 89S52
