Just updated my mac to Mavericks and the latest version of R, and poof, nothing works. Turns out that the good folks who make R decided to change the name of program from R64 or R32 to just plain R. If you run into this issue, just update your /usr/bin symbolic link paths and high five your nearest nerd.
add this to ~/.bash_profile and you should be good to go
Arduino + Open Logic Sniffer…works great.
On the left, is a an old duemilanove with logic sniffer code on it (sniffer), and on the right is another duemilanove (master) wired into a test board for a chip I want to incorporate into a new design (slave). The basic workflow is:
- write code for the host (I use textmate)
- upload via Arduino app
- master starts sending SPI signals to the slave
- record these signals using the sniffer board and software
- modify code
Here’s the relevant links:

(be sure to copy the relevant cfg files into the /ols-0.9.6.1/plugins/ folder)
I’ve already found several timing issues with my code because of this setup. It saves time and money. Happy hacking :)
Thanks Bryan! Good luck with your project!
The force is strong in you. You did not create it, your computer did, because it knows how badly you want to do forest & waterside history research. Boom, you’re a Jedi.
Thanks for writing so many kind notes, you really made my day. I’m SO SORRY I haven’t responded—I for some reason had the alert function off so I didn’t know people were sending me stuff. I just checked my Tumblr messages, and they were just sitting there like “where you been bro?” Anyway, I get alerts now and I’ll write back :)
