Notes
For any digital channel configured as output
Digin_Long
will return an
undefined value.
Digital channels are configured as inputs after start-up. (And thus cannot
be accessed as outputs yet). Channels can be configured as inputs or
outputs in groups of 8.
Conf_DIO
configures digital channels as inputs or outputs in groups of
8. A standard configuration is
Conf_DIO
(
1100b
)
which specifies
DIO00…DIO15 as inputs and DIO16…DIO31 as outputs.
It is preferable to use a binary code (suffix "b") for the bit pattern. This
will make it easier to display the bit pattern than if you use a decimal or
hexadecimal representation although it is still possible to use these.
