A Library for Driving NeoPixels with the ESP32 Micro Controller

The NeoPixel is a very cool little device. It combines three LEDs (red, green, and blue) with a specialized microprocessor, all in a package about the same size as a traditional LED. These smart LEDs open up a wide range of new project possibilities because they reduce the amount of circuitry and processor pins that […]

Adding an OLED to Your Particle Device

I love their product suite because they have abstracted the common functions of IoT products into easy-to-use components while still allowing access to all the nitty-gritty details for those […]

A Simple Message Queue for C

Let’s face it, when you’re doing embedded development, you really don’t have a lot of great tools at your disposal. If you’re lucky, you might have a C99-compliant compiler and a microcontroller with floating-point hardware and DMA. If you’re unlucky you might have a microcontroller that doesn’t actually have a stack and a compiler that […]
