  • FYI, the JST connector link is broken.

  • This tool is fantastic. It can be frustrating to set up serial outputs for debugging i2c communication on the arduino. With this logic analyzer, there is no need to do so. you can see exactly what is going on in the logic lines, and the software decodes everything for you. Worth every penny.

  • Will you be getting more of these in, or has the part been discontinued? I couldn’t find any mention of it on the Polar website.

  • Thanks again! I was using the 0x1E address, so I don’t think that is it. I’m going to try to disable the arduino pullups and see if that helps (not hopeful). I found a thread on the arduino forum where a guy was having problems the the HMC5843 breakout. He ended up having to get two replacement boards before his started talking, so I suspect there were some bad chips in the reel. The thread contained some dead-simple code that did not work on my board. I also modified one of the wire library scripts to just read back the first register on the chip, and it also didn’t work. The ADXL345 and ITG3200 work just fine.

  • Thank you for your responses. I was paranoid about it, so I rigged up a 2-mosfet level shifter before I powered it up. the accelerometer and gyro work fine, but I’m getting no responses from the magnetometer. I’m pretty sure my board has a bad one. I’ve got an email in to sparkfun tech support. I hope these things are still in stock and they can send me a new one!

  • My knowledge of electronics and programming has grown tremendously since I started playing around with Arduinos a couple of years ago. I think the real value for me has been that it has allowed me to solve specific problems quickly without getting too bogged down in the details of exactly how those solutions work. This kept the discouragement level down and the satisfaction level up. As I’ve done more and more, I’ve found that digging into the details became increasingly necessary and so my knowledge has grown. Now I’m designing boards with AVRs independent of arduino. To be fair, I admit that all the AVRs I’ve used are in the Mega8 series (so far).

  • Do I need a logic level shifter to hook this up to the SDA/SCL lines of an arduino?

  • I was having a bad day until I watched this. Awesome.

  • In my opinion, this board should be redesigned. I think a lot of people would buy this for permanent installation in their projects to avoid having to hand-solder a bare micro-sd connector. For this purpose, it would be better if the connector were flush with the edge of the board and it the solder pads were spread around more to increase stability when soldered to a header.

  • Never mind. I found an answer on the arduino forums. This would not work because the arduino doesn’t act as a usb host controller.

No public wish lists :(
