Function
Yes
Usage
data = tsplink.readport()
data
Numeric value that indicates which lines are set
Details
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 the value of bit 3 corresponds to line 3. For example, a returned
value of 2 has a binary equivalent of 010. This indicates that line 2 is high (1), and that the other two lines are low
(0).
Example
data = tsplink.readport()
print(data)
Reads state of all three TSP-Link lines.
Assuming line 2 is set high, the output is:
2.000000e+00
(binary 010)
The format of the output may vary depending on the
ASCII precision setting.
