Hi,
I'm writing an HAL driver that I want to push when I'll finish but I
have a question about RW parameters and the possibility to call a
function when user update its value.
In detail, I have a complicated control word with more bits with
different meanings and values and a constraint like this:
"if you set a flag, the software should reset others".
I created a parameter for each flags/property that user can control
and in my driver I like to call a control function that update the
control word each time user update value of the related parameter with
setp command.
Is possible to associate a function to the update parameter event?
The easiest is probably just to store the 'old' value and at every poll,
check this against the current
value.
If they are different execute the code you want to.
Just need to make sure you initialise the param value properly when the
component starts.
Or is there an other way to make that?
Thanks in advance,
Matteo
