  • Path forward from Arduino to embedded C/C++
    5 projects | /r/embedded | 11 Mar 2022
    There are some design decisions Arduino made that maybe restrict in one aspect, but there's nothing wrong with dropping down to a lower level or jumping sideways to a slightly customized version that does just the right thing. e.g. If digitalWrite() isn't fast enough, somebody wrote a digitalWriteFast() that works with some AVRs. Otherwise, you can probably just hunt down the source yourself, make your own copy of it, and change it to be the way you need. That's a great way to learn, too

  • Using MPU6050 to get orientation
    1 project | /r/arduino | 15 Mar 2023
    There are a few libraries. A popular, easy to use library is the Adafruit Unified Sensor Library collection that exposes an interface for BNO055 and other similar hardware. You can read it as a quaternion format (better for math geeks who like stable orientation) or as a rotation on X/Y/Z axes in either degrees or radians for people who aren't bothered by issues like gimbal lock when you hit a pure up or pure down orientation.
