hyperterminal and reading a variable

shmow · 2008-03-25 17:52

I've never used hyperterminal before, and I'm having a hard time reading the value in
a variable - sample program below:

CON
  _clkmode = xtal1 + pll16x
  _xinfreq = 5_000_000
 
OBJ 
  SER   :"Fullduplexserial"
  
    
pub start   | TEMP_data
  temp_data := 100
  
  SER.start(31, 30, 0, 9600)                            'Sets up Com port for computer (Rxpin,TXpin,mode,baud)
  repeat
   waitcnt(100_000 * 20 + cnt)
   ser.tx(10)                                            'line feed
    ser.tx(13)                                            'carriage return
    ser.str(string("Results =   "))    
    ser.dec(TEMP_data)                                    'display decimal value of temp
    ser.str(string("binary value is   "))     
    ser.bin(TEMP_data,16)                                 'display binary value of temp 
    ser.tx(13)                                            'line feed
    ser.tx(10)

Here's what I have done (and with no luck):
- downloaded·code to prop·(from forum - thanks)· http://forums.parallax.com/showthread.php?p=716483
- opened·hyperterminal on the same com port that was used to program prop
- configured hyperterminal baud rate to 9600
- pressed "Call" icon to connect to prop (through programming cable)
- screen doesn't change - just flashing cursor

Have I overlooked something or assumed incorrectly how to connect.
Any insights would really help.

Are you sure you picked the right com port? The "identify" function in the prop tool tells you what port it's connected to.

Code looks OK.

When I'm downloading the code I use com 12, and when I'm connecting the hyperterminal I use com 12 too.
Is this the right way to do this?

I struggled with hyperterminal when I first started with the propeller. I ran

your code and it worked fine on a hyperterminal sessions. I suggest you

start a new hyperterminal connection with the following settings

Com port = 12·· ( assume· you havent changed it)

bits per second = 9600

data bits········· = 8

parity············· = none

stop·bits········· = 1

flow control····· = hardware

good luck....

Hey Larry, I thought flow control should be set to Off, though I almost never use hyperterminal so I may be mistaken.

You are probably right. In order to check the code, I set up a new hyperterminal session
will the values in my message. It worked OKAY and I was able to display the variable.
Now I am not certain if having flow control set to hardware will create a problem.

I abandoned hyperterminal in favor of propterminal a while back just to avoid issues
when I convert to vista.

Thanks Larry - I got it to work.

In your last message, I read that you use propterminal;

where do I get information on that?

You can download propterminal at http://www.insonix.ch/propeller/.Click on the english translation on the right of the screen, It's a great subsitute for Hyperterminal. Be sure to read the notes that come with it.

Larry, thanks for the link - tried it out and I got it to work too.
