Sending strings

[goldwingers]

How do i send data as a string to the com port. The string would be something like "1,0,1,13,10" equating to

sw1 =1
sw2 = 0
sw3 = 1
cr
lf

I need to send the string as seen (including the inverted commas). The program I am using needs to take this as a string and it is then decoded

Here's one way...

Code: Select all

//decision
if (sw1 = 1)

  //Component Macro
  SendRS232Char("1")

//else

  //Component Macro
  SendRS232Char("0")

//end if

//Component Macro
SendRS232Char(",")

...etc...

Steve do i need to put that in a C code block?

[Steve]

No - that's my shorthand for Flowcode icons.

Hi Steve

I have tried to insert "SendRS232Char("1") " into a send box but it does not accept ("1") or do i need to type in char("1")?

cheers

Hello Ian

Try using '1' instead of "1"

Hi Beng,

The program for my Gui needs the data to be in inverted commas ie
data sent = "1" This is a down fall of the gui program not flowcode.

I have assumed that char (20) is the number for the " so I have tried sending as follows

send rs232 - char20

send rs232 = 43

send rs232 - char20

send rs232 - char 13

send rs232 - char 10

this should give me a string of "43,13,10" but the program im using dont see the inv commas

[Steve]

char 34 is the inverted commas.

Also, sending the number "43" will not send the text "43" - it will send the ASCII character that is 43 (it's "+").
