Using Kinetis Micrcontrollers in low-power applications
Sergei Bezrukov wrote an article on using Kinetis Micrcontrollers in low-power applications: Let us now turn to the microcontroller MKL05Z32. It belongs to the entry level subfamily KL0 of the Kinetis family. Besides of the fine pitch QFN and 48LQFP packages it is also manufactured in easily solderable 32LQFP ones. The microcontroller can be clocked […]
PIC16F1454 used as inexpensive ARM debugger
Peter Lawrence has been working on using a PIC as a CMSIS-DAP ARM debugger. I wanted to see what was feasible in the way of a very-low-cost ARM board. OK, that doesn’t sound original, but stick with me. The solutions that I’ve seen (Tweeny, McHck, mbed, etc.) are limited to wholesale firmware updates. Press a […]
Online course – Embedded Systems: Shape the world
Jonathan Valvano, professor at The University of Texas at Austin informs us of his upcoming embedded systems course. Myself and Professor Yerraballi are teaching a course this semester in collaboration with edX called UT.6.01x Embedded Systems: Shape the world. It is an online class (aka MOOC) introduction to embedded systems. The class starts Jan 22 […]
30C3 Video: Hardware attacks, advanced ARM exploitation, and Android hacking
Stephen A. Ridley gave this presentation at the recently concluded Chaos Communications Conference (30C3) in Hamburg, Germany. He outlines his recent research into practical ARM exploitation on Linux and Android (for embedded applications and mobile devices). He demonstrates these techniques and discusses how they were discovered using several custom built ARM hardware development platforms. He […]
The Beast, a Cortex M4 based development platform
Limpkin writes: “In this article, I’ll present you ‘the beast’: a cortex M4-based platform that has plenty of communication interfaces and to which you can connect a lot of different peripherals.” Visit Limpkin’s page for project details.
Getting started with mbed LPC1114
Here’s a Getting started with mbed LPC1114. mbed porting for LPC1114 was being done by Yoshihiro Tsuboi, Matthew Else and, Toyomasa Watarai: The LPC1114FN28 is an ARM Cortex-M0 based, low-cost 32-bit MCU, designed for 8/16-bit microcontroller applications, offering performance, low power, simple instruction set and memory addressing together with reduced code size compared to existing 8/16-bit architectures. The […]
Self hosted toolchain: The MC HCK as SWD adapter
Simon Schubert writes, “I am happy to announce that we have a self-hosted toolchain: The MC HCK can now act as SWD debug adapter for other MC HCKs, without requiring any other external debug adapters or development boards.” The MC HCK (pronounced: “McHack” [mæk hæk]) is a small, cheap, and versatile ARM Cortex-M4 based microcontroller platform.

If you keep forgetting to water your house plants you might be interested in this plant watering alarm device called […]
Graphical cheat sheets for ARM dev boards
Gordon Williams has developed cheat sheets for ARM dev boards. He writes, “I got pretty frustrated working with ARM development boards – every time I’d choose a pin for some function I’d find out that it was used for some peripheral on the board – so it either wouldn’t work or it would break something […]
