Hi,
Is the data member initialized correctly when you add an entry to the parameter list in the constructor?
eg:
createParam(My_FirstParamString, asynParamInt32, &My_FirstParam_);
It's also a good idea to initialize parameters, after they are created:
setIntegerParam(My_FirstParam__, 0)
(and check that asynSuccess is returned from the set function).
Cheers,
Matt
