bit.getfield()
This function returns a field of bits from the value starting at the specified index position.
Type TSP-Link accessible
Function No
Usage
result = bit.getfield(value, index, width)
result
value
index
width
Details
A field of bits is a contiguous group of bits. This function retrieves a field of bits from value starting
at index.
The index position is the least significant bit of the retrieved field. The number of bits to return is
specified by width.
The least significant bit of value is at index position 1; the most significant bit is at
index position 32.
Example
myResult = bit.getfield(13, 2, 3)
print(myResult)
The binary equivalent of decimal 13 is 1101.
The field at index position 2 and width 3 consists of the binary bits 110. The returned value is decimal 6
(binary 110).
Output:
6.00000e+00
