A number of the STM32 development boards come equipped with a MEMS gyroscope and accelerometer. As shown in the video below, I've written software which displays values from both of these devices in realtime.

In my example, I'm using an STM32F411 development board. As shown on the databri…

I've been working on a number of smaller STM32 projects to get to know the processsor and peripherals better. These include UART communication, DMA, configuring various interrupts, clock speeds and more.

These projects can be found in my GitHub repo. They're well commented to explain what the c…

I obtained an STM32F411 development board recently. Among other peripherals, it has a Cirrus CS43L22 audio DAC on the board and a typical 1/8" adapter allowing you to plug in headphones or typical PC speakers as shown below.

Searching the web, I found a couple of code examples using audio with the…

My PhaseVocoder project is now available on GitHub here. In addition to placing the project on GitHub I've also added some general documentation on how the phase vocoding process works. Please see this document on GitHub for more information.

The PhaseVocoder uses CMake to build on various platfo…

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.
