Accelerometer Basics

March 28, 2013

A quick introduction to accelerometers, how they work, and why they're used.
  • Hah, that’s a great one! Very useful for my personal projects. Thanks for sharing!

  • That’s a really cool project idea!

  • Amperage per phase is the big feature between the two. The Easy Driver is designed to work with smaller motors than the Big Easy Driver. Also, on the B.E.D., you can actually set the microstep resolution down to sixteenth steps, while the Easy Driver only goes to eighth steps. The Easy Driver also breaks out the PFD pin allowing you to control the decay mode. Check out the hookup guides for each to get more of an idea how they each work in an application.

  • From the datasheet for the module: Frequency bands: EGSM900 +GSM850+ DCS1800+PCS1900 Transmit power: Class 4 (2W) for EGSM900/GSM850 Class 1 (1W) for DCS1800/PCS1900 You can find more information on that starting on page 8 of the datasheet linked above.

  • They aren’t tutorials per se, but you can see some of the parts entrants have used in past years here and here.

  • We have several USB to Serial converters but none currently with the type B connector on them.

  • My FT231x board does exactly what I want it to.

    Open-source FTW!

  • Make sure all your transmission rates match up properly. Sounds like there may be a baud rate that doesn’t match. Otherwise, try emailing techsupport@sparkfun dot com with your set up and examples of the data you’re getting back. They’ll be able to assist you further.

  • Thank you for the feedback! We’ll definitely take a look at that the next time this board is up for revision.

  • If you run the command “Show VRAW”, it will highlight all traces labeled VRAW in the schematic. This tool works for any signal/part you’d like to trace out on the board and schematic. Regarding HV_AREF, it is labeled to differentiate it from AREF on the Teensy.
