A Little surprise with PbP 2.50 ...

[Bruce]

Hi Alain,

It is a bit confusing I guess, but maybe this will help explain it.

When you place the degree symbol inside quotes like this "°" the value gets converted to
$B0.

If you send $B0 to a terminal program like this: HSEROUT [$B0] it will display the ° symbol.
If you try this with LCDOUT, the value of $B0 displays a - symbol. Which is what it should
be if you look at the LCD data sheet.

You can use extended ASCII characters like "°öµC" with no problem if sending it to an ASCII
terminal program, and it displays each character just fine. It's just no going to produce what
you might expect when formatting data like this for an LCD display. The compiler "assumes"
data is being formatted for an ASCII terminal.

HSEROUT ["º°A",13,10] ' prints º°A to an ASCII terminal. These were entered with ALT 167,
and ALT 248 on the numeric keypad.

LCDOUT $FE,$C0,"º°A" ' produces ]-A on an LCD, but LCDOUT $FE,$C0,"[]{}!@#$%^&*()_+"
prints everything as shown.

Why 2.5 throws the warning up I'm not sure, but it's probably something they should look
into. Or at least indicate in the manual that ASCII codes >127 aren't supported in quotes.

Hi, Bruce,

thanks for your enlightments.

find here the answer from Melabs :

"
For special characters such as this, it is better to specify the
character using its numeric ASCII code. I believe this will work:

LCDOUT $FE,$C0," ", SDEC2 Tair, $B0, "C "

I believe you could ignore the warning and the display would be
correct, but it's always a good idea to resolve warnings as they come
up.

Assuming Tair = 32d;

Which version prints 32°C on your LCD?

LCDOUT $FE,$C0," ", SDEC2 Tair, $B0, "C "

or;

LCDOUT $FE,$C0," ", SDEC2 Tair, $DF, "C "

or;

LCDOUT $FE,$C0," ", SDEC2 Tair, 223, "C "

My guess: b)

[Acetronics2]

Assuming Tair = 32d;

Which version prints 32°C on your LCD?

LCDOUT $FE,$C0," ", SDEC2 Tair, $B0, "C "

or;

LCDOUT $FE,$C0," ", SDEC2 Tair, $DF, "C "

or;

LCDOUT $FE,$C0," ", SDEC2 Tair, 223, "C "

Hi, Bruce

Seems Charles made a little mix ...

LCDOUT $FE,$C0," ", SDEC2 Tair, $DF, "C "

Works fine on my testboard with every release ... and shows " xx°C " ( xx is SDEC2 Tair )

The special character code ( use HEX !!! ) is to read from your Display Datasheet table.

Well, if $DF works then 223 will work too, isn't it?

Ioannis

P.S. to Alain. Have you seen the image of the LCDOUT command that I posted on #13? Is this what you typed?

Hi, Ioannis

Well, if $DF works then 223 will work too, isn't it?

> I don't know ... exactly, I don't remember !!! ... the code is given in HEX in the Displays Datasheets ... may be the reason is here !!!

>> EXACTLY !!!

Have a nice day

PS: I saw the "Parthenon" had lost some altitude ... Gods will be furious ...

[Ioannis]

I am sure some believers of the old religion will be furious. As for the "gods", I really don't care! They were too human!

Just being curious, what is the meaning of the symbols you were trying to display? I mean OK with the degrees symbol, but the other two?
