Re: 2440: GPIB

Some interesting things being done with Mathematica and Ardinio as well. I do not know anything about hardware but the video here should allow those of you that do the ability to get some insight. I wouldn¡¯t post it if I didn¡¯t think it applied at some level.

?

I mess around programing in Mathematica a bit and have a couple of demonstrations published. I am not recommending Mathematica or anything like that. Just another data point for those of you that are more versed in hardware and interfacing than I. I will say that although Mathematica is C based. Programming in it is enjoyable. I do it just for fun? (ok I know I¡¯m weird) prior I was ¡®ok¡¯ in Fortran and Basic¡­I never did take C...I find Mathematica very straight forward.

?

Mathematica has home user version that is not ¡°outrageous¡± but it isn¡¯t free either. Finally Mathematica is one of the few interfaces with my Linux friends that is transparent/trivial. Everywhere else my being on Windows causes pain when it comes to those things. We freely swap the text files in Mathematica and the rest is taken care of in the background.

?

Again, certainly not indorsing Mathematica just throwing another path/data point out there.

Thanks as always for the bandwidth. Hopefully helpful.

P.S. As a question¡­Is the ability that they can talk to an Ardinio in Mathematica equivalent to being able to do GPIB and stuff like that? I truly am ignorant when it comes to this interface stuff. If the subject is straying too far afield if someone could ping me off forum to converse about it/educate me I would be appreciative. If it is on topic enough I will simply continue to follow the thread.

I once needed to curve-fit to acquired waveform points, but being windows-impaired was deemed unfit to execute John's package.

However I did have Matlab with serial i/o libes on my mac, through which it was straighforward to drive my 7D20 via a Prologix USB/GPIB. Look at message 68773.

As I recall I got no further than testing "hello world" on my 2440; worked fine, but the 7D20 got that particular job done (and there was already a 7K frame up on the bench) so I moved on.

Anyway PM if you want to try and hack my mfile.

PS Definitely not a "cheap" way to go unless you already have Matlab for other reasons! But any other interface or terminal app that can open a serial port can do the same.
