A brief update to let you know how things are going. I’ve got a long checklist of things to implement in the OpenBeacon Mini firmware, and much of it I can leverage from my old OpenBeacon 2 firmware (although quite a bit of that needs to be refactored and updated). However, one bit that I… Read More OpenBeacon Mini Firmware Coding Proceeds
Since I’m waiting for circuit boards for OpenBeacon Mini to arrive, I want to keep the waiting time as productive as possible, so I’ve been working on the firmware. Specifically, one of my recent goals was to factor all of the modulation code out of the spaghetti mess that is the current state of the… Read More A New Arduino Library Appears!
Arduino – Si5351 Powered Signal Generator Please enjoy this write-up of a nifty, compact signal generator project using the Etherkit Si5351A Breakout Board driven by a Teensy LC. What I really love about it is that it uses an 18650 LiPo cell with a small USB charge controller, so that it is very portable. Neat stuff!
As mentioned in the last Wideband Transmission, I recently viewed a presentation from CppCon 2016 which convinced me that a lot of my preconceived notions about the (lack of) suitability of C++ for use in microcontroller applications might be misplaced. The standard lore (go ask Wes Hayward W7ZOI his opinion of lore) states that C++… Read More Arduino C++ Investigations – Introduction
OpenTechLab If you’ve been reading my blog for any amount of time, you’ve probably observed that I’m a big fan of all things open source, especially on the hardware side of things. One area where OSHW seems to be lagging a bit is in the test & measurement department, so it was a very pleasant… Read More Wideband Transmission #10
I know that the updates here have been extremely sparse. For that I do apologize. Things are slowly starting to settle into a new normal around here, and I’ve been able to regain the ability to put time back into work. There’s a large to do list on my whiteboard, and many of the things… Read More Break My New Library
Arduino in the Cloud I saw a recent post on the Make blog about the new cloud ecosystem for Arduino which has been dubbed Arduino Create. Since this will most likely be the future of Arduino, it seemed wise to get an early look at the platform. It includes quite a few features, but the… Read More Wideband Transmission #9
Happy New Year 2015! 2014 was a bit of a mixed bag here. It’s been a transition year for Etherkit, as I reorganize and reorient the business for a renewed push to get the CC1 and other new products to market. I believe that good things are beginning to happen there. On a personal level,… Read More Wideband Transmission #6
I appreciate all of the interest in the Si5351A Breakout Board that I have available on OSHPark. I apologize for not having this available sooner, but here is a GitHub repository which hosts the KiCad design files and a PDF of the Breakout Board schematic, which lists the part numbers for the reference oscillator and… Read More Si5351A Breakout Board Documentation
A few exciting developments here on the Si5351 front. First off, I took the C code from my Si5351 library for avr-gcc and converted it to an Arduino/C++ library, which you can find here. It replicates the functionality in the avr-gcc library, but makes it quite a bit easier to rapidly implement designs. I’ve tested… Read More Si5351 Libraries and Breakout Board
