<h2>Explanation</h2>
|
|
<p class="PlainText"><span class="keyword_in_text">DEBUGIN</span> provides a convenient way for your BASIC Stamp accept input from
|
|
the use via the Debug Terminal. <span class="keyword_in_text">DEBUGIN</span> can wait for, filter and
|
|
convert incoming data in powerful ways, using the same techniques and modifiers
|
|
as <a href="SERIN.htm" target="" title="" alt="" class="MCXref_0" xrefformat="{paratext}">SERIN</a>.
|
|
|
|
</p>
|
|
<p class="PlainText">This simple example waits for a number from the user, then prints a message
|
|
the specified number of times: </p><pre class="BScode" xml:space="preserve">
|
|
lines VAR Nib
|
|
idx VAR Nib
|
|
|
|
Main:
|
|
DEBUG CLS, "How many lines to print (1 - 5)? --> "
|
|
DEBUGIN DEC1 lines
|
|
|
|
IF ((lines >= 1) AND (lines <= 5)) THEN
|
|
DEBUG CR, CR
|
|
FOR idx = 1 TO lines ' print message specified times
|
|
DEBUG DEC1 idx, ". "
|
|
DEBUG "BASIC Stamp!", CR
|
|
NEXT
|
|
END ' end of program
|
|
ELSE
|
|
DEBUG CR, "Invalid entry!" ' warning message
|
|
PAUSE 2000 ' wait 2 seconds
|
|
GOTO Main ' get another entry
|
|
ENDIF
|
|
</pre>
|
|
<p class="PlainText">After you download this program, the BASIC Stamp Editor will open a Debug
|
|
Terminal on your PC screen and wait for an entry from the user. Since the DEC1
|
|
modifier is used with <span class="keyword_in_text">DEBUGIN</span>, the program will ignore all keys except
|
|
"0" - "9". If the value entered is between 1 and 5, the message will be printed,
|
|
otherwise the program will display an "Invalid entry" message, then loop back
|
|
and wait for another entry.</p>
|
|
<p class="PlainText"><span class="keyword_in_text">DEBUGIN</span> is actually a special case of the <span class="keyword_in_text">SERIN</span> instruction. It
|
|
is set for inverted (RS-232-compatible) serial output through the programming
|
|
connector (the SIN pin) at 9600 baud (BS2, BS2e, BS2sx, BS2p, and BS2pe) or
|
|
19.2 kBaud (BS2px), no parity, 8 data bits, and 1 stop bit.
|
|
For example,</p><pre class="BScode" xml:space="preserve">
|
|
DEBUGIN DEC1 lines
|
|
</pre>
|
|
<p class="PlainText">...is exactly like:</p><pre class="BScode" xml:space="preserve">
|
|
SERIN 16, $4054, [DEC1 lines]
|
|
</pre>
|
|
<p class="PlainText">...in terms of function (on a BS2). The <span class="keyword_in_text">DEBUGIN</span> line actually takes less
|
|
program space, and is obviously easier to type.</p>
|
|
<p class="PlainText">The tables below list all the available conversion formatters and special
|
|
formatters available to the <span class="keyword_in_text">DEBUGIN</span> command. See the
|
|
<a href="SERIN.htm" target="" title="" alt="" class="MCXref_0" xrefformat="{paratext}">SERIN</a> command for additional information and examples

<li value="1">All numeric conversions will continue to accept new data until receiving

|
either the specified number of digits (ex: three digits for DEC3) or a

non-numeric character.</li>
|
|
<li value="2">To be recognized as part of a number, the minus sign (-) must immediately
|
|
precede a numeric character. The minus sign character occurring in non-numeric
|
|
text is ignored and any character (including a space) between a minus and a

number causes the minus to be ignored.</li>

the same as "A" through "F".</li>
|

<li value="4">Indicated hexadecimal and binary formatters ignore all characters, even
|
|
valid numerics, until they receive the appropriate prefix ($ for hexadecimal,

% for binary). The indicated formatters can differentiate between text and

hexadecimal (ex: ABC would be interpreted by HEX as a number but IHEX would

ignore it unless expressed as $ABC). Likewise, the binary version can

|
distinguish the decimal number 10 from the binary number %10. A prefix

occurring in non-numeric text is ignored, and any character (including a

space) between a prefix and a number causes the prefix to be ignored. Indicated,

signed formatters require that the minus sign come before the prefix, as
