    i have to one small project using PIC 18fxxx to connect 4 IR (all are receiver not a transmitter) to receive 4 different data serially (with short time interval almost near to simultaneous)..

    is it possible ha..
    coz it only one serial port how to interface all the other 3..
    is that any latch
    guide me plz

    Are they all different frequencies?

    What's doing the transmitting?

    no all receivers work under same frequency.
    but i need to connect 4 receiver cant share they as one receiver..

    transmitter i have got the design but the receiver stuck

    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
