Butterfly & Ladybug, STM32L4-Based Arduino-Programable Development Boards

Arduino boards are very useful for beginners to get started with building hardware projects. But at some point, more powerful controller than the Arduino’s 8 MHz one will be needed, featuring faster clock rate, floating point engine, and rich peripherals. As Kris Winer found, the code editors and compilers for these controllers aren’t as simple …

β€œChipiplexing” efficiently drives multiple LEDs using few microcontroller ports

Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the β€œCharlieplexing” method as an effective way to drive M=NΓ—(N–1) LEDs using only N bidirectional I/O ports and N resistors (reference 1 and reference 2). Unfortunately, using Charlieplexing allows you to drive only …

EmbeddedLab introduces us TI’s Tiva C MCUs

Most of us who work with electronics know the name of Texas Instruments (TI) as a manufacturer of several important digital and analogue ICs as well as fancy sophisticated scientific calculators. However many people don’t know that TI is also a manufacturer of some of industry’s best microcontrollers. TI’s portfolio of micros is pretty large. …

AmpStrike – Battery Powered Bench Power Supply

AmpStrike – Battery Powered Bench Power Supply

Introduction This is a small bench power supply that is powered by two lithium-ion batteries. The project was inspired by Dave Jones from EEVblog but the design is completely mine. The voltage range is 0-20V regulated in 10mV steps and maximum current is 1A with current limit set in 1mA steps. Schematic Linear Voltage Regulator …

Programming an ATtiny w/ Arduino 1.6 (or 1.0)

This tutorial shows you how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. These are small, cheap ($2-3) microcontrollers that are convenient for running simple programs. The ATtiny45 and ATtiny85 have eight legs and are almost identical, except that the ATtiny85 has twice the memory of the ATtiny45 and can …
