0 | Bit 0: State |
This IOType reads the state of a single bit of digital I/O. The direction setting of the IO will not be changed. When the digital IO is set to output the actual state of the line is read. Only lines configured as digital (not analog) return valid readings.
IO Number: 0-7=FIO, 8-15=EIO, or 16-19=CIO.
State: 1=High, 0=Low.
Example
PY
# BitStateRead Feedback command
# read the state of a single bit of digital I/O. Only digital
# lines return valid readings.
# return 0 or 1
import u3
d = u3.U3()
d.debug = True
d.getFeedback(u3.BitStateRead(IONumber = 5))
