Two new helper methods in pyubx2 v1.2.48 - val2twoscomp and val2signmag - may help with ESF-MEAS configuration

[semuadmin]

pyubx2 version 1.2.48 adds two new helper methods:

1. val2twoscomp - converts signed integer to two's complement format, suitable e.g. ESF-MEAS speed dataField.
2. val2signmag - converts signed integer to sign magnitude format, suitable e.g. ESF-MEAS wheel tick dataField.

example usage ("U024" is the attribute type, 024 signifying the attribute length in bits):

from pyubx2 import SET, UBXMessage, val2signmag, val2twoscomp

msg = UBXMessage(
    "ESF",
    "ESF-MEAS",
    SET,
    timeTag=1000,
    numMeas=2,
    dataField_01=val2twoscomp(-10, "U024"),
    dataType_01=11, # speed
    dataField_02=val2signmag(-24, "U024"),
    dataType_02=10, # single wheel tick
)

print(msg)

<UBX(ESF-MEAS, timeTag=1000, timeMarkSent=0, timeMarkEdge=0, calibTtagValid=0, numMeas=2, id=0, dataField_01=16777206, dataType_01=11, dataField_02=16777240, dataType_02=10)>
