stupid question #1024

Archiver

im looking at bs1 application dice.bas. my bs2 doesnt like "if pin7
=
1 then Roll". How do you read the pin statis on the bs2? Bill

Archiver

Try:

if in7=1 then Roll

Bill-

Some options:

IF IN7 = 1 THEN Roll

or

IF IN7 THEN Roll

or

widget_active VAR IN7
...
IF widget_active THEN Roll

It's helpful to think of the I/O pins as variables which may be
addressed as bits (e.g. IN7), 4-bit nibbles (e.g. INA.LOWNIB), 8-bit
bytes (e.g. INA), or a 16-bit word (INS). As with any other
variable, you can assign an alias, such as widget_active, to refer to
the variable by a useful name of your choice.

The Stamp's true/false determination is based on the principle that a
zero value is false and anything else isn't. So if IN7 is high (1),
it's true for the IF statement's purposes. That's why "IF IN7 THEN
Roll" and "IF widget_active THEN Roll" work.
