@Warren. Thanks. In the "output pane" at tha bottom of the start proyect pane, the "lpf" files are not shown,. However, they are shown in the "file list" pane. Why is that? are they generated automatically?
Lattice Nano "Environment Scanner" reference design output to UART/COM port. Lattice responded saying that ref design was built with a prev version of Diamond and needs it's "strategy" changed. They have not yet said how to change it.
I'm still not clear if that ref design using the Micro8 or not...
? @Warren: I programmed the I2C SPI Master C demo to see the temperature value displayed on the eval board's LCD and it displays values only on the lcd when I cover the sensor. What would I need to do to see data on the terminal program (Putty)? I have pointed to COM9 which is the port of my usb connection.
Thanks for the advice. I have been doing some review of manufacturer info and more recently performing web searches for discussions on such comparisons but not finding an easy time of sorting through all the "chatter" to get to the kernel of useful info. I will return to the manufacturer sites and start with the basics.
@bangor077- You can program FPGAs in C either for the hardware or for the on-chip MCU. The version of C used for the hardware isn't standard C however, it is a special case for hardware (parallel) implementation.
Xilinx and Altera both have info on using C on their web sites.
I was running the diamond sw with the users guide example " mixed_code_SC counter" with device lcmx02-1200ze. Which synthesis third party tools do not work welll with lattice sw? and what are the common problems?
? Which example project do you recommend as an easy one to start with? Is there one that has a step by step tutorial to get someone unfamiliar with the environment from opening the project to downloading to hardware? I've opened a couple, but not sure where to start.
I bought a Cool Runner board a while back, but had the same problem, so never did anything with it.
@Gbabecki- The best way to compare various manufacturers FPGAs is to look at their web sites and see what types of example and reference designs they provide. This shows you what they think their parts are good for!
@Warren Can you summarize or otherwise point to a good comparison of various manufacturer FPGA families? I know there are differences regarding logic and interconnect architectures, onboard flash vs. RAM program memory, low power claims, onboard peripherals, etc. Worst case I drag out the various datasheets and perform a side-by-side comparison but I thought I would ask if you have some explicit knowledge or good references.
Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.
You are eligible to earn IEEE Professional Development Hours by attending these courses and participating in the chat function. Additionally, we are no longer using the points system, offering "graduation", or giving grades. The IEEE hours are taking the place of that. There are some important things for you to know about earning the hours. The most important ones are that you need to attend these courses live, you need to attend a minimum of two of them per semester, you need to fill out a course evaluation form within 2 weeks of the end of the class, you need to attend 4 out of the 5 classes per course, and you need to participate in the chat function every day you attend. Please click on the link at the top of this page that says "How do I earn IEEE professional development hours" to read all of these important details and more.
@Warren Working from home today due to weather. I have Diamond installed at work but not at home. Trying to download now (but Lattice site is fairly slow and file large). Are we going to need it for Today's class?
Please join our Digi-Key Continuing Education Center LinkedIn Group at http://linkd.in/yoNGeY and be sure to follow @designnews and @DigiKeyCEC on Twitter for the latest class information. We encourage you to tweet about today's class using #DigiKeyCEC.
The streaming audio player will appear at the top of this web page when the show starts at 2 PM Eastern time today. When you see it, click on the play button to start the audio. Note however, that some companies block live audio streams. If when the show starts, the audio bar doesn't appear or you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser. Some users experience audio interruptions with IE. Also, make sure your flash player is updated with the current version. If that doesn't work, the class will be archived immediately following our live taping. You shouldn't experience any problems with the audio when listening on-demand.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
