    Default trying to built own LVP

    I am trying to make a Low-Voltage ICSP using the Parallel Port for a 16F886. All I want it to do is write BSF 05h,1 to the Program Memory. I want to know if it will work.

    dim j as ubyte
    dim i(29) as ubyte
    i(1)=0
    i(2)=1
    i(3)=0
    i(4)=0
    i(5)=0
    i(6)=0
    i(7)=0
    i(8)=0
    i(9)=1
    i(10)=0
    i(11)=1
    i(12)=0
    i(13)=0
    i(14)=0
    i(15)=0
    i(16)=0
    i(17)=0
    i(18)=0
    i(19)=1
    i(20)=0
    i(21)=1
    i(22)=0
    i(23)=0
    i(24)=0
    i(25)=0
    i(26)=1
    i(27)=0
    i(28)=0


    out 888,1
    sleep 1000

    for j = 1 to 28
    out 888,3
    if i(j)=1 then out 888,7
    sleep 1000
    if i(j)=1 then out 888,5
    if i(j)=0 then out 888,1
    sleep 500
    out 888,1
    sleep 500
    next j

    sleep 5000
    out 888,0
