“Chipiplexing” efficiently drives multiple LEDs using few microcontroller ports
https://www.electronics-lab.com/chipiplexing-efficiently-drives-multiple-leds-using-few-microcontroller-ports/
by Guillermo Jaquenod @ edn.com Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” method as an effective way to drive M=N×(N–1) LEDs using only N bidirectional I/O ports and N resistors (reference 1 and reference 2). Unfortunately, using Charlieplexing […]
TV Tuner IR remote with a PIC16F684
https://www.electronics-lab.com/tv-tuner-ir-remote-with-a-pic16f684/
Tahmid built a TV tuner IR remote with a PIC16F684: I then proceeded to write an IR transmitter using the PIC16F684 (using the MPLAB X IDE and XC8 compiler), following the timing information from the extended NEC protocol. In order to connect all the keys, I connected them in matrix keypad form. In order to power the […]
New PIC32MM family consumes as little as 500 nA
https://www.electronics-lab.com/new-pic32mm-consumes-little-500-na/
by Clemens Valens @ elektormagazine.com: The new PIC32MM family, currently Microchip’s lowest power 32-bit PIC32 family, features sleep modes down to as little as 500 nA. Filling the gap between the PIC24F XLP and PIC32MX families, the new family also offers so-called core independent peripherals that once initialized can function without intervention of or loading […]

An Introduction to MSP430 Launchpad
https://www.electronics-lab.com/brief-introduction-msp430-using-launchpad-msp430g2553/
Rahul Sreedharan introduces us to TI’s MSP430 microcontroller using LaunchPad board. In this tutorial we will be exploring the workings of a MSP430 based microcontroller from Texas Instruments. MSP430 is developed by Texas Instruments as an extremely low power 16 bit architecture for use in low power, low cost, energy constrained embedded applicationsThe Hardware used […]
EmbeddedLab introduces us TI’s Tiva C MCUs
https://www.electronics-lab.com/embeddedlab-introduces-us-tis-tiva-c-mcus/
Shawon Shahryiar @ embedded-lab.com introduces us to Tiva C series microcontrollers from TI. The Tiva C series MCUs are high performance ARM Cortex M4F micros. Now what does that mean? Generally speaking the ARM Cortex M series is meant to be used in place of (or simply replace) regular microcontrollers like PICs and AVRs while […]
samDEV_09 – Mini devboard for Atmel’s SAMD09 ARM Cortex M0+ Microcontroller
https://www.electronics-lab.com/samdev_09-mini-devboard-atmels-samd09-arm-cortex-m0-microcontroller/
A Basic board to test the Atmel SAMD09. On board there is also a CH340 uart to usb bridge Build this board to getting started with the SAMD microcontroller family after I made the mistake to try the much bigger SAMD21 first. The SAMD09 used here is he smallest from this family and therefore has […]
