5: BASIC Stamp Command Reference – SEROUT

BASIC Stamp Syntax and Reference Manual 2.2 • www.parallax.com • Page 421

SEROUT 1, 16780, ["Hello", CR]

SEROUT 1, 16780, ["Num = ", DEC 100]

The above code will display "HELLO" on one line and "Num = 100" on the

next line. Notice that you can combine data to output in one SEROUT

command, separated by commas. In the example above, we could have

written it as one line of code, with "HELLO", CR, "Num = ", DEC 100 in the

OutputData list.

The BS1’s SEROUT command is limited to above-mentioned features. If

you are not using a BS1, please continue reading about the additional

features below.

The SEROUT command can also be configured to pause between

transmitted bytes. This is the purpose of the optional Pace argument. For

example (9600 baud N8, inverted):

SEROUT 1, 16780, 1000, ["Slowly..."]

Here, the BASIC Stamp transmits "Slowly..." with a 1 second delay

between each character. See Table 5.104 for units of the Pace argument.

One good reason to use the Pace feature is to support devices that require

more than one stop bit. Normally, the BASIC Stamp sends data as fast as

it can (with a minimum of 1 stop bit between bytes). Since a stop bit is

really just a resting state in the line (no data transmitted), using the Pace

option will effectively add multiple stop bits. Since the requirement for 2

or more stop bits (on some devices) is really just a "minimum"

requirement, the receiving side should receive this data correctly.

Keep in mind that when we type something like “XYZ” into the SEROUT

command, the BASIC Stamp actually uses the ASCII codes for each of

those characters for its tasks. We could also typed: 88, 89, 90 in place of

“XYZ” and the program would run the same way since 88 is the ASCII

code for the “X” character, 89 is the ASCII code for the “Y” character, and

so on.

The decimal formatter is only one of a whole family of conversion

formatters available with SERIN on all BS2 models. See Table 5.110 for a

list of available conversion formatters. All of the conversion formatters

work similar to the decimal formatter. The formatters translate the value

into separate bytes of data until the entire number is translated or until the
