To that end, here's a reminder that the Call for Papers is out and the deadline is looming. Safe MCU Design: Testing MCUs for Class C Ryszard Milewicz, Design Engineer, RAT Electronics, 5/17/2013 Comment now 7 comments In a previous blog, I talked about MCU component testing for Class B software requirements. Now I'll discuss what should be tested for Class C. Most recent post, Ryszard Milewicz, 5/20/2013 6:18:34 PM For automotive industry IEC 61508, ISO 26262 are applicable.

MCU Low Power: What Does the Future Hold? Warren Miller, Independent Consultant, 5/15/2013 Comment now 50 comments In this post I will finish up a recent discussion I had with Rob Cosaro, systems applications and architecture manager with NXP Semiconductors. Most recent post, bobt, 5/20/2013 11:07:39 PM andyk1 in reference to your comment on TI Cortex-M0 Interesting article. TI developed... Simple Windows Programs Support MCU Audio Test Curt Carpenter, Retired Engineer, 5/14/2013 Comment now 14 comments I've been continuing my exploration of TI's (now obsolete?) Stellaris Launchpad board, with particular attention to its two independent 1Msps A-to-D converters. Along the way I've written two simple programs for my PC that have proven useful in this effort. I thought I'd share them here. Most recent post, Curt Carpenter, 5/20/2013 11:10:11 PM Ill have to try it and see what happens (which was, after all, the whole motivation... Help Define MCC Discussion Groups Rich Quinnell, Editor in Chief, 5/14/2013 Comment now 20 comments One of the most underutilized resources in the Microcontroller Central community is the Reader Message Board section. Here is an idea for how we can change that situation, and provide ourselves with a place to have on-going discussions on popular topics. Most recent post, Rich Quinnell, 5/20/2013 9:27:53 PM Microp, thanks for the clarification, I hadn't realized you were proposing the combination... Telepresence Robot Update – Implementing Web Control Duane Benson, Marketing & Web Development Manager, Screaming Circuits, 5/13/2013 Comment now 10 comments I've been blogging off and on about the telepresence robot design project I have underway, mostly discussing the overall architecture and some motor control details. Recently, I've been making progress with the interfaces that allow me to use the robot over a web connection. So, I figured it was time for a status update. Most recent post, duanebenson, 5/17/2013 1:23:37 PM David - Thanks! Interesting article too. One of the things I've been pondering... Avoid Stupid Project Scheduling Tricks Wil Blake, Engineer, Embedded & Mobile Systems, 5/10/2013 Comment now 22 comments One of the most bemusing and recurring MCU development challenges is establishing, maintaining, and improving realizable schedules.

New Book Explains BeagleBone Basics Rich Quinnell, Editor in Chief, 5/9/2013 Comment now 17 comments The new BeagleBone Black is out and quick on its heels has come a book telling you how to use it. Bad to the Bone from Morgan and Claypool Publishers provides a handy guide to learning about both the BeagleBone boards as well providing projects to work on. It's well worth getting your hands on, especially if you're relatively new to MCU-based design. Most recent post, Rich Quinnell, 5/20/2013 9:19:45 PM Looks like a handy link, David. Started looking at it and will finish once I have... Temperature Sensing for MCUs – Conditioning the Signal Aubrey Kagan, Engineering Manager, Emphatec, 5/9/2013 Comment now 22 comments In my first blog on temperature sensing I discussed the generalities of the different temperature measurement techniques. In this blog I will deal with converting the temperature into electronic signals. We'll start with purely analog conversion. Most recent post, antedeluvian, 5/20/2013 8:09:41 PM Hi David Is there some new chip for this application ? Well yes and no. The Cypress... MCU Development Kit Takes Kickstarter Journey Tyler Gilbert, Embedded Engineer, CoActionOS, Inc., 5/8/2013 Comment now 11 comments I recently launched a Kickstarter project for a microcontroller development board that has a pre-installed, open-source OS. Learning how I came to this point might be helpful to others who dream of taking a similar journey. Most recent post, raul, 5/16/2013 3:02:40 PM Looks like a lot of work but lots of fun too!

TI developed a Cortex-M0? I thought that had been done by ARM ;-) Besides state retention, you need a stable oscillator within 400ns, that can be a challenge. I did... bobt on MCU Low Power: What Does the Future Hold? 5/20/2013 10:54:16 PM Re: Alias: Michael, you are correct. Generating anything other than a sinewave with a DDS at a frequency that is a significant fraction of the sample frequency will generate spurs. However, with a PC, it is easy to use a large table because the generator... Didier_Juges on Simple Windows Programs Support MCU Audio Test 5/20/2013 10:07:20 PM Re: Alias: Sorry if I was unclear. My point was, if you try to output anything other than a sine at any frequency above a few hertz, you'll get aliasing in the analog output – unless you prefilter your wavetables. See Designing a DDS Signal... MD on Simple Windows Programs Support MCU Audio Test 5/20/2013 9:40:59 PM Re: wireless charging: RQ: "Its sole benefit is convenience, although in certain cases that benefit is quite compelling." Rich, people can see and feel convenience, but energy efficiency is hard to see. We get many conveniences by using energy. TheMeasurementBlues on MCU Low Power: What Does the Future Hold? 5/20/2013 9:34:45 PM Re: wireless charging: Agreed: wireless charging is not nearly as energy efficient as a direct connection. Its sole benefit is convenience, although in certain cases that benefit is quite compelling. Rich Quinnell on MCU Low Power: What Does the Future Hold? 5/20/2013 9:31:36 PM Re: Discussion Group: Microp, I may just start with the ones that are significantly more popular rather than try to set up a specific number of groups and need to break a tie. Right now there are six with double-digit counts, so they seem like the natural ones to...

Rich Quinnell on New Book Explains BeagleBone Basics 5/20/2013 9:15:24 PM Re: Raspberry Pi: David, I had not heard the generic term "mini PC" but it makes some sense. Yes, the Pi is a specific brand, so having a generic term is a good idea given all the similar devices coming on the market. I used the term single board computers...
