tsplink.readbit()
This function reads the state of a TSP-Link synchronization line.
Type
TSP-Link accessible
Affected by
Where saved
Default value
Function
Yes
Usage
data = tsplink.readbit(N)
data
The state of the synchronization line
N
The trigger line (1 to 3)
Details
Returns a value of zero (0) if the line is low and 1 if the line is high.
Example
data = tsplink.readbit(3)
print(data)
Assume line 3 is set high, and it is then read.
Output:
1.000000e+00

tsplink.readport()
This function reads the TSP-Link trigger lines as a digital I/O port.
Type
TSP-Link accessible
Affected by
Where saved
Default value
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.
