Output:
1.00000e+00

Function
Yes
Usage
data = digio.readport()
data
The present value of the input lines on the digital I/O port
Details
The binary equivalent of the returned value indicates the value of the input lines on the I/O port. The
least significant bit (bit B1) of the binary number corresponds to line 1; bit B14 corresponds to line 14.
For example, a returned value of 170 has a binary equivalent of 000000010101010, which indicates
that lines 2, 4, 6, and 8 are high (1), and the other 10 lines are low (0).
Example
data = digio.readport()
print(data)
Assume lines 2, 4, 6, and 8 are set high when the I/O port is
read.
Output:
1.70000e+02
This is binary 10101010
