In FPGA design, interfacing over AXI (ARM eXtensible Interface) is an increasingly popular choice due to its status as the most widespread AMBA interface, enabling the connection of potentially hundreds of Masters and Slaves in complex SoCs. Download the new eBook: FPGA Design - Interfacing Over AXI Using A Simple Address Data Bus However, it does add in an additional layer to managing IP. Time has to be spent supervising and generating IP outputs before they can be incorporated into the mainline project, and simulating the design can be a challenge in itself! One option that significantly reduces the overhead is to choose BRAM, which helps interface to AXI without the need to handle the AXI bus directly and removes concerns about potential issues that are not related [...]
ByteSnap and consortium partners begin breakthrough V2G development project We’re pleased to announce that ByteSnap and a consortium of partners have been awarded a two-year collaborative project, VIGIL (Vehicle-to-Grid Intelligent Control), under a Vehicle-to-Grid competition, funded by the Office for Low Emission Vehicles (OLEV) and the Department for Business Energy and Industrial Strategy (BEIS). The other partners in the Vehicle-to-Grid (V2G) consortium are: Aston University Nortech Management Grid Edge VIGIL – spearheading the UK’s smart energy market The VIGIL project is focussed on developing a new communication and control platform for Vehicle-to-Grid/Building (V2G/V2B) systems: an off-vehicle system that controls how, when and the rate at which electric vehicle batteries are charged/discharged with respect to local substation constraints and EV/building energy requirements. V2G consortium [...]
In electronics product development, touchscreens can be difficult to stress test; and whilst there are several sophisticated systems available for touchscreen stress testing, there are other ways to get the job done – like a low-tech approach… For example, take a look at this rig built from a child’s toy. Our engineer built it as part of the debug process to try to fix a failed touchscreen unit. Thanks to our brightly-coloured debugger, we discovered that the touchscreen controller chip itself was unreliable. The rig kept tapping the screen over and over and over again. However, what the debug process uncovered was that it took slightly more than a mere tap-tap-tap motion to uncover the bug. So: Tap-tap-tap motion = unit functioning normally. Tap-slide-and-up motion (closer to an actual [...]
Catch our embedded electronic designers caught up in some trade show time travel - in this whistlestop tour of our stand at Railtex 2015. With remote monitoring a primary concern for the rail industry, we displayed our low power remote monitoring station and 10km data logger at last month’s rail exhibition, at Birmingham’s NEC. Watch 4 days in just over 1 minute It was our first time attending Railtex 2015 - the UK's biggest rail show - so a big thank you to the visitors and customers who stopped by our stand. Enjoy the video!
ByteSnap will unveil a high reliability, low power remedy to the rail industry’s remote monitoring headache at Railtex 2015 in May. Custom Electronic Design The demonstration consists of two units; a remote monitoring station and a rugged waterproof data logger. The solar-powered station transmits weather data via a 10 kilometre low-power radio link. The practical applications for and benefits to rail infrastructure maintenance are substantial. Low Power Monitoring Director Dunstan Power said, “We see that low power monitoring equipment, which can be installed in remote locations transmitting information in real time over long distances, is vital to addressing reliability requirements of the rail industry. "We design bespoke solutions for customers; this is just an example of our expertise in rugged, very low power designs that can be adapted for [...]
Placed on several categories of products, CE marking is mandatory for machinery, electrical and electronic equipment, medical devices, personal protective equipment and toys. So if you are looking to sell an electronics product in the EU, you will need to affix a CE mark. Here’s a quick round up of interesting facts about CE marking: CE marking is a self-declaration where a manufacturer proves compliance with EU health, safety and environmental protection legislation and confirms a product's compliance with relevant requirements CE is Conformité Européenne (French) which means European conformity With a CE mark, your product can be sold in the EU and in some other countries, including Turkey CE directives affect manufacturers, importers and distributors/retailers, though a manufacturer is responsible for acquiring the CE mark There are six steps to [...]
Compliance testing can be a sting in the tail of a project. Selling products within the European Union requires a CE mark, whilst other territories have their own strict protocols. EMC testing services don't come cheap as the companies need to recoup the large investment they have made in capital equipment, as well as the time of the testers. What's more, many of the testing engineers are discouraged from giving advice on how to fix problems, as it can conflict with their role as testers. When quotes are given by test houses, they usually assume that the device will pass first time. In reality this is often not the case and it is down to the skill and knowledge of the design engineer to fix the problems. Whilst he is [...]
One of our clients, the National Oceanography Centre, has hit the headlines by deploying the UK’s largest-ever marine robot fleet. The NOC is leading a pioneering group of research and corporate partners to test new technologies in marine electronics development, and better understand how the sea works. The project, launched off the Plymouth coast, will run for three weeks before scientific data is collated and analysed at the end of October. It's the biggest survey of its kind in Europe - check it out on the BBC News website.
