Beaglebone Black I2C Tutorial

beaglebone black i2c

I2C is a popular communications protocol and is used by a lot of sensors and devices. This is why most microcontrollers, including Arduino, PICs and STM32 have I2C support. In this tutorial, we will look at how to use the I2C protocol on the BBB and create a simple Beaglebone Black I2C application.

Beaglebone Black ADC: Reading Analog Voltages

beaglebone black adc

One of the most important things your microcontroller can do is read analog voltages. It is important particularly in interfacing with sensors where most throw varying voltage levels that represent varying physical quantities (temperature, pressure, etc.). Microcontrollers, including the Beaglebone Black, have analog to digital converters to do this. Here I will show you how to use the Beaglebone Black …

Serial Communication with Microcontrollers

microcontroller serial communication

When working on projects, there'll be lots of times when your microcontroller needs serial communication to talk to other devices or other micros. The most common example of this is adding IoT capabilities to your Arduino board or PIC using ESP8266 or GSM module.  A number of sensors and LCD displays also send and receive data serially.

Beaglebone Black Blink LED using C++

beaglebone black blink LED

The first thing I did when I had my Beaglebone Black (BBB) was toy with it using C++. The "hello world" of embedded programming is LED blinking so that's what I did. Note that the BBB has user-accessible on-board LEDs and controlling them is very similar to the method outlined here. What I did is create a Beaglebone Black blink LED …
