tsplink.readport()

This function reads the TSP-Link synchronization lines as a digital I/O port.
Type TSP-Link accessible
Function Yes
Usage
data = tsplink.readport()
data
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 Bit B3 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).
Example
data = tsplink.readport()
print(data)
