Hi list, I hope the following is not too offtopic and if it is, feel free to answer privately. Does anybody happen to know or work with linux-gpib driver? you may find details on http://linux-gpib.sourceforge.net. Ive sent the following 2 messages to the linux-gpib-general mailing list, but nobody answered me up to now. I hope somebody on this list may help me. I forward this message and another one, relating to 2 different subjects. Thanks, Rafi. -----Original Message----- From: Rafi Cohen [mailto:[EMAIL PROTECTED] Sent: Monday, December 18, 2006 1:08 PM To: [EMAIL PROTECTED] Sourceforge. Net Subject: primary address of devices
Hi, sorry in advance if some of my questions are too basic and even not logic. My application needs to support connecting up to 30 devices (actually gsm simulators) to the gpib board in the computer. All those devices have the same primary address (pad) of 14 and no secondary addrss. They have a way to modify in advance their pad. However: 1. If I did not modify the pad of those devices and left all of them with 14, what would happen if I issue an ibdev() in my application? will it return an error or there will be an attempt to open one of the devices? The second option would be excelent as immediately after openning any device with this pad, I could issue an ibpad() to change it's pad to any other address except 14, but logically I believe the first option will happen. 2. Is there a way for the application to obtain the pad of any device connected to the gpib board _before_ openning this device thru ibdev() or ibfind()? Is there any function that does this or should I manually input this pad either to the application or to the gpib.conf file? 3. If I want to open a device using ibfind() thru it's name as entered in the gpib.conf file, am I free to give whatever name to each device or is there a limitation for this name to match something related to the device? I hope my questions are clear, thanks, Rafi. -- No virus found in this outgoing message. Checked by AVG Free Edition.
