Tag: I2C

This article describes a set of minimal I2C routines for the new 0-series and 1-series ATtiny and ATmega microcontrollers. They allow any of these processors to act as an I2C Master and connect to I2C peripherals. As an example of their use I've designed a digital clock circuit based on...

We have built quite a number of weather stations in several past tutorials, with each one differing from the other by the use of a different sensor, different display, etc. Today, we are going to build another weather monitoring station using the BME280 Temp and humidity sensor from...

A USB hub that's also a dev board and an I2C, GPIO, and SPI bridge In addition to being a 4-port USB 2 High-Speed hub, this Programmable USB hub is also: A CircuitPython based development board. A bridge between your computer and I2C (via Sparkfun Qwiic connectors), GPIO, and...

A few weeks ago, we examined the features of ESP32 module and built a simple hello world program to get ourselves familiar with the board. Today, we will continue our exploration of the ESP32 on a higher level as we will look at how to interface a 16×2 LCD with it. Displays provide a...
