With about 900 exhibitors the Embedded World reached a size where it is impossible to “see it all”. Yes, you can still walk by all booths in a day, but you might easily miss hidden highlights. It was quite obvious that IoT – the Internet of Things – is a current hype. To me this is quite astonishing as already some 10+ years ago we built an “Embedded Internet Demo” – at that time based on a Philips 8051 with a dial-up modem connected. The main difference between now and then is that now smart phones are widely spread and we are “always online” and now can access our embedded devices “at any time”. Among the visitors one could recognize a lot of skepticism for what exactly we really need the IoT, other then it being hip and cool to be able to control “everything” with our smart phone.
An unusual approach to get remote access to embedded applications was shown by Raisonance (http://www.iotize.com) – they have a miniature NFC or Bluetooth module that connect to the JTAG/SWD debug port of an application. So it can be added to any application with debug port, sometimes even without the need to re-compile the code, if you have the knowledge where in memory the variables are that you want to have remote access to. A great tool to get started with IoT without requiring a re-design of existing hardware.
At the CiA (CAN in Automation) booth a CAN FD demo integrated devices and tools from multiple vendors. CAN FD (Flexible Data) allows higher bit rates and longer contents (up to 64 bytes) of the data frame. Especially bootloader applications and other software update features benefit from the higher data throughput. For such applications it seems to be possible to increase the effective data throughout 8 fold easily, potentially even more.
We at ESAcademy further enhanced our portfolio of CANopen Diag products. There is now a second hardware, based on PEAK’s mini Display, that offers a subset of the diagnostic features provided at a price point of well below 1000 Euro. The CANopen Test Machine System part of the CANopen Diag now allows to create tests based on MS Visio graphs. The transitions in a state diagram can be used to transmit or receive a CAN/CANopen message or to influence/set/test/query variables or timers. More details and examples will be published shortly.
The new LPC4000 family of microcontrollers from NXP Semiconductors combines two powerful ARM Cortex cores in one microcontroller. The integrated Cortex-M4 and Cortex-M0 can run asymmetrically at up to 150MHz and have access to internal memory of up to 1MB Flash and 264k of RAM.
A multilayer bus matrix with 4 separate RAM blocks ensures that both microcontrollers have independent, fast access to “their” memory, minimizing wait-states.
Next to the “usual” LPCxxx peripherals the new devices also feature high-speed USB and an AES decryption engine for security.
There are several applications that benefit from a dual core solution. If a lot of communication is required, like handling complex communication protocols with specific timing requirements, a dual-core solutions allows using one core as a communication co-processor, clearly separating communication and process handling.

I was visiting Embedded World this week and in regards to microcontrollers the trend towards 32bit continues. When it comes to marketing presence at a trade show, obviously less than 32bit where not “it” this year. Not only chip manufacturers, but also most of the development tools primarily focused on 32bit solutions. And the next impression one gets walking the aisles: ARM processors are the first choice in this arena, with a focus on the Cortex-M generation. At this year’s Embedded World, no other microcontroller architecture had a marketing presence anywhere near that of ARM. Read more…
Whenever a new microcontroller generation comes out, developers and engineers look out for evaluation boards. In order to be able to test the microcontroller, it needs to be mounted on a PCB that has the required glue logic, power circuitry and connectors. For generations, these test boards were mostly “bare-naked” – without housing and only featuring components needed to test the microcontroller in certain types of applications. Over the last years more “attractive” variations of such boards have come to market, for example some looking like a custom USB stick.
Last year, Raisonance released products following a slightly different concept they named Primers, and the Primer2 won an EETimes product of the year 2009 award. These boards feature a complete housing, making them more attractive for various prototype developments. Through staging several design contests, many applications have been implemented and are now shared on the product’s web page. Applications include an alcohol meter, a CAN monitor, a GPS displaying OpenStreetMap data, various games and many more. Read more…
