Re: EPICS-Arduino Serial Communication via Asyn-Stream Drivers

[Hulusi Öz <hulusi.oz1@gmail.com>]

Thanks for your response,sir. I have followed your instructions,and I did it. And, I've got other output from the IOC boot ,I think it's an acceptable output. It just says no reply from device within 1000ms. But as I said that it's acceptable since I've just checked out the connection between EPICS and Arduino. I've done for right now except the preparing the protocol text files.

Therefore, I tried to write a basic protocol files that just read analog input,but I don't know that it's true or not. Here it is :

Terminator = LF;

get_analog {

    in " %f";

    ExtraInput = Ignore;

}

I want to use this in CAEN Digitizer,since I could deal with the Arduino,I suppose..

But,the thing is that when I connect the digitizer to the computer via USB, the IOC output says like that :

2016/07/27 09:28:55.056528 SERIALPORT SERIALPORT:input: asynError in read: Can't set "/dev/v1718_0" c_cc[VTIME]: Inappropriate ioctl for device

2016/07/27 09:28:55.056871 SERIALPORT SERIALPORT:input: I/O error after reading 0 bytes: ""

2016/07/27 09:28:55.056913 SERIALPORT SERIALPORT:input: Protocol aborted

2016/07/27 09:28:55.556477 SERIALPORT SERIALPORT:input: asynError in read: Can't set "/dev/v1718_0" c_cc[VTIME]: Inappropriate ioctl for device

I installed the CAEN driver for this product (Digitizer DT 5730 in <http://www.caen.it/csite/CaenProd.jsp?parent=14&idmod=757>) at the path "/lib/modules/4.4.0-31-generic/kernel/drivers" . When I connect it, to learn which port number that it uses , v1718_0

The way I learnt it is that :

ls /dev > notplugged // then I plug the Arduino

ls /dev > plugged

diff notplugged plugged.

Its result for the Arduino says, Serial /ttymACM0,and it works. However the result for the Digitizer says, USB v1718_0 .

I am using Asyn Driver and StreamDevice.. I don't know that should I use another extensions or support for this product: I search on this website but I couldn't find..

Thanks in advance..
