STM32 Gyroscope / Accelerometer Demo (Video Included)

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

Various STM32 Projects

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.

Audio Output with the STM32F411 Microcontroller

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.

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…
