Reads the state of a digital input channel. If a configurable I/O channel (DIO00–DIO15) that was config-
ured as a digital output is read by
digIn
, then the value read will be the state of the output channel.
A run-time error will occur for the following conditions:
1.
channel
out of range.
2.
brdInit
was not executed before executing
digIn
.
PARAMETER
channel
is the input channel number (0–15 for DIO00–DIO15, 16–31 for IN16–IN31).
RETURN VALUE
The logic state of the specified channel (0 = low or 1 = high).

brdInit, digOut, digOutConfig, digInBank
Reads the state of a bank of 8 digital input channels. If a configurable I/O channel (DIO00–DIO15) that
was configured as a digital output is read by
digInBank
, then the value returned will be the state of the
output channel.
A run-time error will occur for the following conditions:
1.
bank
out of range.
2.
brdInit
was not executed before executing
digInBank
.
PARAMETER
bank
is the bank of digital input channels to read.
0 = DIO00–DIO07 (bank 0)
1 = DIO08–DIO15 (bank 1)
2 = IN16–IN23 (bank 2)
3 = IN24–IN31 (bank 3)
RETURN VALUE
The logic state of each channel in the specified bank (0 = low or 1 = high). The data is returned as a byte,
with each bit representing the state of a particular channel in the bank ordered from the most significant
bit to the least significant bit.
