# How come?

How come when I run either of the below listed programs: pin0 sends out a "1"
pin1 sends out a "2"
pin2 sends out a "4"
pin6 sends out a "64"
pin7 sends out a "128" on the serial line?
Is there a way to do it so that when pin2 goes high it sends out a 3 , then pin6 sends a 4 and pin7 going high sends out a 5?

Do: if pin0= 1 then SEROUT 2,N2400,(1)
else SEROUT 2,N2400,(0) endif
if pin1= 1 then serout 2,n2400, (2)
else serout 2,n2400, (0) endif
if pin2= 1 then serout 2,n2400, (3)
else serout 2,n2400, (0) endif
if pin6= 1 then serout 2,n2400, (4)
else serout 2,n2400, (0) endif
if pin7= 1 then serout 2,n2400, (5)
else serout 2,n2400, (0) endif
Loop

#Picaxe 18x
do
b0=pins & %00010010
if b0<>b1 then
serout 2,n2400,(b0)
b1=b0
end if
loop

I dont know if this is the problem but try:

Do: if pin0= 1 then SEROUT 2,N2400,("1")
else SEROUT 2,N2400,("0") endif
if pin1= 1 then serout 2,n2400, ("2")
else serout 2,n2400, ("0") endif
if pin2= 1 then serout 2,n2400, ("3")
else serout 2,n2400, ("0") endif
if pin6= 1 then serout 2,n2400, ("4")
else serout 2,n2400, ("0") endif
if pin7= 1 then serout 2,n2400, ("5")
else serout 2,n2400, ("0") endif
Loop

Still the same

I should have mentioned that these are the results I get when running the code on the simulator.

SO.....

So if I use that code for my transmitter, I have to set my reciever up so that it decodes 0,1,2,4,64 and 128? Since I want it to be only number for each pin. Thanks alot for teaching me this. I have wanted to learn about it for so long but reading just confused me I learn way better by doing.

You are confusing byte values with characters with serout. When simulating, because you are using non-ascii byte values (very low values), when you look at the simulated serial output it is shown in brackets. This is because it is a non-printing character.

sevs3 has already given you a program that will work as you want, by putting the digit 1-7 character in " " speech marks you get a correct ascii character sente.g. "2" not 2

Code:
``````serin 1,n2400,b1
if b1 = "1" then

else if b1 = "2" then
etc..``````

So Im clear

Just so Im clear, Even though the simulator is showing it recieved the 1,2,4,8,64, etc .,when used in hardware it will really be putting out "1","2","3","4"? If I use the code sevs3 gave me? Thanks , sorry for being kinda slow But I just REALLY want to understand this.

This might help.
When you put something in " " it's a ASCII character, leave them out and it's a decimal.
So "0" would = 48 (%00110000) and "A" would = 65 (%01000001).
