On top of this I like to make a small suggestion for asyn :)
there is all these diferent drivers in: asyn*Base.c
But in debugging there is really no way to tell which one is running :)
So My suggestion is to change the asynPrint lines in
registerInterruptUser and CancelInterruptUser to include something like
"(int32Array)"
e.g.
asynPrint(pasynUser,ASYN_TRACE_FLOW,
"%s %d registerInterruptUser (Float64Array)\n",portName,addr);
Then it's fairly clear where we are in the code :)
Anyways, just an idea (Would've spared me a atleast 2 hours debugging..
lol)
bye
