Presenting at St. Louis C++ Meetup on August 9th

I'll be presenting some of my experiences using C++ for embedded development, specifically my ARM Cortex-M4F Synthesizer project, at the St. Louis C++ Meetup next month (August 2017). The meeting is free and open to the public. Please RSVP on the Meetup site here.

My ARM Cortex-M4F Synthesizer (Video Included)

Here's the current status of my ARM Cortex-M4F Synthesizer. Using a Tiva LaunchPad (ARM Cortex-M4F) development board and some various circuitry for MIDI input and audio output I've created a fully functioning synthesizer as shown in the video demonstration below.


The code is written in C…

Tiva LaunchPad (ARM Cortex-M4) LCD Menu System - Video Included

I've interfaced my Tiva LaunchPad (ARM Cortex-M4) development board with a small LCD screen as shown in the video below. The LCD screen is a Newhaven display, model number NHD-0420H1Z-FL-GBW-33V3.


Below is a circuit diagram I've drawn to show how everything is setup. It's fairly simple as…

Using μDMA with the Tiva LaunchPad (ARM Cortex-M4) for Audio Output

I've figured out how to use DMA (direct memory access) on the Tiva LaunchPad (ARM Cortex-M4) microcontroller when using peripherals like an audio output DAC (digital to analog converter).

Tiva Launchpad, Logic Analyzer and DAC Annotated

The DMA controller on the Texas Instruments Tiva LaunchPad is known as "micro-DMA" and is abbreviated as "μDMA…

Thoughts on "Making Embedded Systems" by Elecia White

I recently finished reading Elecia White's book "Making Embedded Systems: Design Patterns for Great Software". Elecia is a highly experienced professional embedded software engineer and also host of one of my favorite podcasts, Embedded.fm.
