Excursion to the bare-metal: ARM Cortex vs MIPS
2015-11-18 12:16 by Ian
One of the projects I did for Microchip was a feasibility study of porting the ARM Cortex instruction set to comparable routines for MIPS. The ultimate goal for the chipKIT team is/was to port the Teensy3 audio library to their line of PIC32 dev boards. What follows is my report, along with some elaborations for readers who want the knowledge, but aren't yet level 60 mages.

This post is aimed at programmers-in-general, and covers some general stylistic perspectives.
Data structures (Priority queues)

This will be an examination of one of the two key data structures in ManuvrOS: The Priority Queue.
255mph intro to C++ Templates
2015-06-20 21:37 by Ian
When writing programs (no matter the language [human or otherwise]), you will repeat yourself. Unavoidable. Templates are a C++ feature that allow us to write the form of the code once, and rely on the compiler to replicate it for each unique type we use with it.
First r1 renders

These renders are of a left-handed unit, but very careful attention was given to design things to be achiral down to the last possible level.

This is a brief recount of my experience using the iPack P401 Module.
Arduino library for the MGC3130
2015-05-13 06:38 by Ian
This post will cover the theory-of-operation of a driver for Microchip's weird and wonderful MGC3130 e-field gesture sensor. I will be using Microchip's Hillstar dev kit for the MGC3130, a chipKIT Fubarino Mini, and MPIDE. But the library ought to work with any other Arduino-esque microcontroller provided it has Wire.h.
Live data, wirelessly, with full quaternions

CPU not even breaking a sweat. All 17 IMUs are returning good data (with quaternions) in synchronized frames.
MurumLux: Overview
2015-05-12 22:20 by Ian
This is a high-level overview of MurumLux (Latin: "Wall of light"). It is a demo piece I built using Microchip's current top-of-the-line microcontroller. The chipKIT team wanted something eye-popping and fun to use for the bay area Maker Faire (May 2015). This is what I rolled for them.
