SEROUT,HSEROUT or DEBUG ? max 232 or no max232 ?

[Dennis]

Have tried N2400 ... no luck :-(
Correct me if I'm wrong but surely is well if the string arrives correctly ?

[Darrel Taylor]

DEFINE LCD_RWREG 0 'defines the port where R/W line is connected to (set to 0 if not used)
DEFINE LCD_RWBIT 0 'defines the pin where R/W line is connected to (set to 0 if not used)

I don't think it's a good idea to set those to 0.
It will end up overwriting bit0 at address 0 in RAM which is normally PBP's R0 system variable.

Try it without those lines.

Darrel ....
10 points on spotting this issue ... dude can I borrow those 'fine-tooth comb code-eyes' ???

So I removed the lines...
and here are the results .....
1. LCD response is a million times faster.
2. Keypresses happen almost instantly now
3. The LCD was not responding to

lcdout $fe,1          'clear lcd screen

Now it responds like it should ...each keypress displays correctly, no funny wingdings like characters :-)
and ... the LCD display clears after every keypress :-)
YAY
The LCD and keypress system is working like it should WOOOHOOOOO !!

Thanks a million
:-)

Kind regards
Dennis

PS... I still want to know how you noticed that ?? Past experiences ?

Now all that remains is solving my SEROUT variable passing issue so I can see proper characters in hyperterminal :-)
I keep getting a little square in hyperterminal as the keypress occurs but on the LCD it appears correct :-(

the key pressed isthe key pressed isthe key pressed is

now I am confused....

[Dennis]

At least I'm not alone then :-)

I'm sure it has to do with passing the variable 'cos a 'string like this' appears just fine !

And if I LCDOUT myvar that works fine on the LCD

What doesn't work fine is when I SEROUT the variable myvar and try read it in hyperterminal

WEIRD or what ?

In fact with SEROUT using N2400 the output is worse and even the string of text is wingings :-)
See next post here for the output screenshot... this tells me that T2400 is correct !

See the Received window

WOOHOO!

Well, I do have 4 eyes, so I guess you can have a couple of them.
Need a new pair of specs anyhow.

For the SEROUT prob...
Steve's keypad routine returns a result that represents the number of the key. For a 4x4 pad it's 1-16.

With a LOOKUP statement you can change them to match your keypad ...

LOOKUP  myvar,[0,"123A456B789C*0#D"],myvar

?Is Steve mister e ??
Code-wise I tried , Bruce's code and Trent Jackson's code ....
Mister e's is what I'm using at the moment, it was the one that worked for me, but the other would probably work now that the LCD problem is cleared up ;-) ...

Where is the keypad code you are referring to ? I am willing to give it a bash :-)

Kind regards

Dennis

Oh and I sure did get my fair share of moving wires and resistors around to get the correct column and row assingments ;-)
Roll on virtual ports hey ?

[Darrel Taylor]

Yup, Steve is mister-e.

By changing from key numbers to ASCII with the Lookup, your serout should work better.

Darrel :-)

So with 8 sets of eyes in total now ... should I add the LOOKUP prior to making the assembly key lookup like this ?

start:
        'read keypress variable 
        @ READKEYPAD _myvar 
        LOOKUP  myvar,[0,"123A456B789C*0#D"],myvar
        'lcdout $fe, 1        'clear lcd screen
           'pause 2000
        lcdout dec myvar      'display keypress variable myvar
   
   'transmit section
        SerOut PORTC.6,T2400,["the key pressed is",myvar] 'SerOut PinNumber2,T2400,DataRec
        pause 1000
   'transmit section ends
        
    'receive section 
         'SerIn PORTC.7,T2400,DataRX       
         'LCDOUT datarx          'displays data received from serin datarx
    'receive section ends
        lcdout $fe,1          'clear lcd screen
        
goto start

Kind regards
