Let's take a look at what makes 'main()' feel so cozy and welcoming - what has to happen to have variables initialized, objects constructed and stacks a-stackin?

SparkFun LoRa Gateway 1-Channel Hookup Guide

November 15, 2018

How to setup and use the LoRa Gateway 1-Channel in Arduino.
  • You're correct about Arduino being stuck with it and this is an excellent solution in most cases! The situation where a hardware solution might begin to be attractive is when you are trying to max out the effective data rate - either to boost the update rate (framerate) or trying to increase the total number of LEDs while still hitting a target update rate. Your solution is also reminiscent of the extended SPI functions that we were able to include in the Apollo3 Arduino core - transferOut and transferIn (just one benefit of maintaining your own core!)

  • FYI Arduino core is now at version 1.0.24 Don't be alarmed - all the same improvements are still there and the instructions still apply

  • Wow! As you can probably tell my perspective is very different - coming from the side where I've never had to think about such things until just recently. The barrier to entry today is so wonderfully low - I can get my brother to learn the basics as long as he has a web browser! Thanks for the story. (And thanks for the typo catch - I'll go ahead and fix it)

  • To control a mouse I would recommend using the ICM with a Teensy - they have a good HID USB library that includes mouse examples. Then you can use the ICM data to informt he mouse movements

    Depending on what you want from gesture commands and how much effort you want to put into this you might be able to adapt the 'magic wand' example from TensorFlow for your own platform and to use data from the ICM.

  • We have a temporary fix in place - you should be able to get both packages simultaneously now. Use the new link for the Atto84 package index JSON file. In the future we might adopt a more permanent solution so check back occasionally.

  • Hey there, I just got this to a workable state. If you want to try it out and let me know how it goes that would be great. Specifically I want to make sure that the instructions make sense and that the workflow is tolerable. artemis_dev_platform

  • This is a great idea. I recently took an introductory course on Docker and had a few experiments setting up the Apollo3 environment in an image. I put that on hold b/c I thought it would be too difficult to edit the files you might need for development w/o a GUI interface in the container. But...... your articles show a good way to link across the boundary. Then I presume one would edit SDK and source files with their editor of choice and then run the build in the container.

    I have been working on a much-improved set of tools and resources to get started with the SDK. We are going to release updated documentation sometime soon-ish (lots of work to do on Apollo3/Artemis yet) but in the meantime check it out here: Our upgraded copy of the AmbiqSuite SDK: https://github.com/sparkfun/AmbiqSuiteSDK The BSP repo that supports all our boards (the main upgrade to the SDK): https://github.com/sparkfun/SparkFun_Apollo3_AmbiqSuite_BSPs

    Thanks for those links!

  • OH! I thought that was a typo and you meant 'with the arduino nano ever' haha. Okay thanks for clarifying. I'll look forward to your report on GitHub so I can better understand your setup. In the meantime I can't think of a particular reason why this library would be incompatible (it uses strictly Arduino-standard interfaces AFAIK)

  • Could you post more details in an issue on GitHub? I just tried compiling 'Example1_DisplayTest' with 'Arduino Nano' selected as my board in Arduino 1.8.10 and everything completed successfully. By the sound of it I would bet that you have some extra libraries laying around.

  • That functionality is not built-in, but you could add it yourself relatively easily. https://github.com/sparkfun/SparkFun_HyperDisplay/issues/2

No public wish lists :(
