The above is a selection of the 16 different options available for the
parameter. When a digital channel has been selected as an output, it can then be set
on or off with the

To set digital channels 1 and 2 to input and digital channels 3 and 4 to output:
directionOut =
HRDL_DIGITAL_IO_CHANNEL_4 (8) + HRDL_DIGITAL_IO_CHANNEL_3 (4) = 12
To set digital channel 4 high and digital channel 3 low:
digitalOutPinState = HRDL_DIGITAL_IO_CHANNEL_4 (8) = 8
To set only digital channel 3 high:
digitalOutPinState = HRDL_DIGITAL_IO_CHANNEL_3 (4) = 4
To turn both digital channels 3 and 4 on:
digitalOutPinState =
HRDL_DIGITAL_IO_CHANNEL_4 (8) + HRDL_DIGITAL_IO_CHANNEL_3 (4) = 12
