Progresso

Soo.... John had a lot of questions today, and we worked on a couple VIs. This capturing sound idea is quite a bit to chew. Just taking in a lot of information, and it is taking me down some complex roads. We'll get there though, or at least have a pretty good understanding of why we can't get there. Pick one.

Have a great weekend.

push it to the limit

So today we did a lot of research and conversations about things we were working on. I will post the updated VI from before for download as an edit to this blog entry later.

fixed the blinkers

With the help of Kyle we figured out that since we were plugged into the digital I/O and the high pins we needed to change the vi somewhat to reflect this. This sort of thinking about problems helps. We must remember that we are not only writing code (or perhaps drawing it in this case), we are also interacting with an electronic circuit board. Picture of the VI is included.

Good information on data acquisition from fpga's

In my research I came across a helpful example showing a host file doing data acquisition. The downloadable file was written in labview 8.6 which is incompatible with 8.5 but the pictures of the block diagram are none-the-less interesting.

What I've been doing this week

I am posting what I have been working on this week. Hopefully it makes sense to some people. I have included a link to download all of the files I have been working on.

Sound Acquisition

Hope you enjoy!

learning FPGA's

For anyone learning LabVIEW FPGA I recommend the NI demo that was recommended to Kyle. It offers a good groundwork to work from that helps the user understand what the wizard creates and how each piece works together. I have included the link for future reference.

Analog sampling, so it begins

Just reading through some tutorials about analog sampling.. Great buzz words for sampling are sampling rate, Nyquist's thereom, quantization, and dithering.

Also, here is what I have been going through today as well:

Quite a lot to learn.
