If all receivers are the same freq I don't really see the advantage over using one receiver.

no bro. its no like tat actually i'm making a demo model in tat i'm trying to place tat 4 IR in different locations k..

and collecting the all datas and giving it to the controller clear ha..

so the reason of 4 IR is its collecting information form 4 different location.

but i have to use only one controller (its a order of my supervisor) for receiving all the data..

tell me is it possible and how plz...

i don't know y but i tried all the bootloaders which are found in net but all failed..

non of them detecting my PIC (using max232)
i tried bootloader from microchipc 9.7 (http://www.microchipc.com/PIC16bootload/index.php)
but its display a msg
searching for bootloader

after tat no response

i checked my circuit
nothing is wrong (unfortunately my multimeter got repaired i just continuity of wire all good but cant check appropriate current rating i hope current cant be big problem)

then i kept the led on the crystal but it is not glowing (I'M NEW TO HARD COMPONENTS OF PIC I'M JUST A STUDENT)

i tried to download some other prog (after tat boot file fail using icprog106B)
my led (but not bright as led on supply) on the o/p of max232 (+5)
blink but if try to read tat from pic non of the led blink..

also i read most previous threads of other ppl and solution but i have no idea on this prob.

tell me

1)what that its show is my pic dead..
how i can i check it i bought a week before its new..
is there any other way to check the pic

2)y that boot loaders are not functioning

3)wat can i do next to for boot programmer
