Hi Just want to make sure about something and what is the general practice that should be used. When an interrupt callback is called. Then there is an parameter to send the "new" data in also. Ok so when the record support code's interrupt callback is called it already receive the new data... But it can obviously still call the read command for the asyn interface and get the data that way. So do we assume that the data passed to the interrupt callback is correct and that no further asyn calls is needed. Or can/should it still call the read function to get data? I'm assuming it accepts the data in the callback and go ahead with that as that would make sense to me. -Heinrich
