tsplink.readbit
Function Reads the state of a TSP-Link synchronization line.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage data = tsplink.readbit(n)
data A custom variable that stores the state of the
synchronization line.
n Synchronization line to be read (1 - 3).
Remarks • Returns a value of 0 if the line is low and a 1 if the line is high.
Details See TSP-Link synchronization lines in Section 8.
Also see tsplink.readbit, tsplink.readport, tsplink.writebit.
Example Assume line 3 is set high, and it is then read:
data = tsplink.readbit(3)
print(data)
Output: 1.000000e+00
tsplink.readport
Function Reads the TSP-Link synchronization lines as a digital I/O port.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage data = tsplink.readport()
Remarks • The binary equivalent of the returned value indicates the input pattern on the I/O port. The least
significant bit of the binary number corresponds to line 1 and bit 3 corresponds to line 3. For
example, a returned value of 2 has a binary equivalent of 010. Line 2 is high (1), and the other 2
lines are low (0).
Details See TSP-Link synchronization lines in Section 8.
Also see tsplink.readbit, tsplink.writebit, tsplink.writeport
Example Assume line 2 is set high, and the digio I/O port reads:
data = tsplink.readport()
print(data)
Output: 2.000000e+00 (binary 010)
