ACTIVITY #6: INTRODUCING ASCII CODE
In Activity #4, you used the
number in the Debug Terminal. But what happens if you don’t use the
with a number? If you use the
the BASIC Stamp will read that number as an ASCII code.
Programming with ASCII Code
ASCII is short for American Standard Code for Information Interchange.
microcontrollers and PC computers use this code to assign a number to each keyboard
function. Some numbers correspond to keyboard actions, such as cursor up, cursor down,
space, and delete. Other numbers correspond to printed characters and symbols. The
numbers 32 through 126 correspond to those characters and symbols that the BASIC
Stamp can display in the Debug Terminal. The following program will use ACSII code to
display the words “BASIC Stamp 2” in the Debug Terminal.
Example Program – ASCIIName.bs2
'What's a Microcontroller - ASCIIName.bs2
'Use ASCII code in a DEBUG command to display the words BASIC Stamp 2.
'{$STAMP BS2}
