Matter Alliance

Posted by ralphjy Top Member Jun 19, 2021
I just saw an interesting post on c|net about Matter Alliance.  Apparently it is a consortium of companies to bring interoperability to smart home devices.  It has major players like Apple, Google, and Amazon involved. https://www.cnet.com/videos/the-matter-alliance-could-finally-fix-the-smart-home   It's interesting because in addition to having the right companies involved, it is also open-source.  I guess this has roots in project-chip (connected home over ip) and Zigbee ...
I'd previously used a SparkFun RP2040 Micromod with a Big Display Carrier Board to try Luke Wren's Bit-Banged DVI RP2040 HDMI Display .   I saw that Adafruit had designed an inexpensive ($1.95) Breakout Board that would allow you to do this with any board that had the capability to drive the 4 differential signals required for DVI.  Adafruit DVI Breakout Board - For HDMI Source Devices .  Seemed like a fun thing to try with the RPi-Pico.   Here's a picture from the product ...
I've found Jupyter Notebooks to be very useful for interactive Python development.  I first started using them with the PYNQ-Z2 and most recently running machine learning models in Google Colab.   I had hoped to see a few AI example notebooks on the UnitV2, but it turns out there was only a single example notebook covering basic interface functions - check Python version (3.8), control LEDs via GPIO, communication over Grove UART, camera image capture and display.   It's funny ...
I just received my UnitV2 that I described in a previous post M5Stack UnitV2 - Standalone AI Camera for Edge Computing and thought that I'd do a quick run though of the OOB applications on the device.   Initial connection and operation is reasonably straightforward.  There is an Ethernet over USB interface on the board as shown in the block diagram:     Note: there are a couple of mistakes in the diagram - DDR3 memory size is 128MB and NAND Flash is 512MB.   Connect ...
M5Stack recently released the UnitV2 which is totally different from the earlier UnitV (and quite a bit more expensive!).  I have found the StickC devices to be very handy and have used them in a few projects.  I have been interested in the StickV and UnitV products since they came out a couple of years ago because they integrated an AI camera in the very small StickC form factor.  They both use the Kendryte K210, an edge computing system-on-chip(SoC) with dual-core 64bit RISC-V C ...
