The traffic is encrypted, but I found the decryption algorithm. I used a logic analyzer to log all the I2C traffic. Like an oscilloscope, it’s like having a third eye that sees electrical signals with bullet time (multimeters are too slow).Ī good example of when it came in handy is when I was making my own Wiimote extension. Good ones can cost thousands of dollars.īut assuming you are a hobbyist or a student who just need make a few sensors talk, I seriously recommend you to save money for a low cost logic analyzer as soon as possible. Logic analyzers might sound like really expensive equipment, and they are. I’ve never read the manual and I’ve figured out the software pretty much inside out by now. Also I think he didn’t setup the UART analyzer options properly.
The triggering options were pretty obvious and intuitive, but he just didn’t see them. Plus, watching Dave use the Saleae software is cringe worthy. The Saleae Logic holds a special place in my heart because I’m pretty sure it’s responsible for a lot of my success. I have written this from the point of view of a hobbyist, especially a poor one. This post isn’t really a review, it’s more like a piece of advice.
Dave Jones, from the EEVBlog, recently did a review of the Saleae Logic, and he basically bashed it because he’s been working in the EE field for decades and owns equipment worth many thousands of dollars.
