Mario Bergeron recently did a tutorial project on Hackster.io vitis-ai-1-1-flow-for-avnet-vitis-platforms that "provides detailed instructions for targeting the DNNDK samples from the Xilinx Vitis-AI 1.1 flow for Avnet Vitis 2019.2 platforms."&...
3.5 Capacitor Characterization An ideal capacitor can be specified by a single value: its capacitance. Here I will show how I measured 2 capacitor non-idealities: the dielectric absorption and the dielectric leakage. Dielectric absorption ...
This is a blog post in support of a RoadTest Review for ACCESS:bit for micro:bit . I established a format of a documenting my RoadTest process through a series of blog post. The RoadTest Review itself, is a summary of findings that refers back ...
I've been using PYNQ on the PYNQ-Z2 and Ultra96v2 boards and I thought that it could prove useful for evaluating and prototyping with the UZ7EV. Unfortunately there isn't a prebuilt PYNQ image for this board yet. The good news is that Pet...
July 4, 2020I had hoped to finish the VCU TRD design tests this week and move on to taking a closer look at the design and using the design tools to tweak it to verify that I have a good tool setup.Unfortunately, even the simplest things sometimes tu...

Getting started with the STM32H7B3I-DKPosted to support the STM32H7B3I-DK - DISCOVERY KIT roadtest. The following items are recommended by ST to explore and test the various features of the STM32H7B3I-DK:Java 8.241STM32CubeIDE 1.3.0STM32Cu...
A few days ago I received the Genesys ZU board to work with it and submit a RoadTest. This opportunity came right on time for me, as I have been particularly interested in Hardware Acceleration (Hardware Design for Multi-Modal Data Acquisition and Pr...
3.3 DC-DC converter efficiency measurement The use of DC-DC converters has become almost universal in modern electronics. One important factor that needs to be evaluated, especially when the power comes from a battery, is the conversion efficien...
3.2 Battery Characterization Battery selection for a specific application can depend on multiple factors: price, size, weight, safety and its electrical properties. Manufacturers are known for making dubious claims about their batteries lifetime...
Initial Hardware TestsI've started to learn my way around this board - it has a tremendous amount of capability/functionality. My plan is to use the VCU Design example (v2018.3) to learn the board (SOM + Carrier) and test the functionality that...
I was fortunate to have been selected to test a second Avnet UltraZed-EV Starter Kit that Randall and the sponsor added to the original roadtest. Things got off to an inauspicious start as a train derailment somewhere between Chicago and Portla...

Completed work on road testing the Tektronix AFG31052 Signal ARB/Function Generator First, I would like to express my thank you to Tektronix and Element14 for selecting me to roadtest the AFG31052 Arbitrary Function Signal Generator. ...
GPIOGPIO pins are 'general purpose input/output pins', configurable as both input and outputs where needed. These pins form the most common interface to hook up your own hardware.According to the hardware description, the maaxboard has no less than 5...
InterfacesAfter playing around with the image a little, it was time to connect the maaxboard to the outside world. The first things I wanted to try was to use the i2c interface, since that was my preferred bus to hook up my sensors. I2C is a bus wh...
After the initial setup and installation, I have put some more time into testing of the software, covering the following topics:Linux DesktopI finally found the setting in my archaic HDMI monitor to turn off the 'overscan' feature, so I now h...
I have received the Maaxboard this week, and I can finally start testing. I was afraid shipping would be affected by the Corona measures, but it came by UPS, and there was no hassle at all. The UnboxingThe maaxboard came in a plain brown cardboa...
