We talk a lot about making the OpenScope MZ<\/a> as open source as possible, and the resources that are available. If you forgot, you can find information about the design and schematics on the Digilent Wiki<\/a>, and source code for WaveForms Live on the Digilent Github<\/a>. We’ve started seeing some ideas for contributions to WaveForms Live<\/a>\u00a0as well as discussion on the hardware design, and hope to see much more. A new video<\/a> published on the Digilent YouTube<\/a> channel we hope will inject some inspiration into those conversations.<\/p>\n

Keith Vogel and John Day, Lead Engineers on the OpenScope MZ presented a Masterclass at the 2017 Microchip MASTERs Conference.<\/a> Microchip filmed it for us and we’re able to post it on the Digilent YouTube to share. The class is designed to be a detailed design review of the OpenScope MZ. It goes through the hardware and the firmware, design considerations, design decisions that had to be made, and has a ton of great content to learn from.<\/p>\n

The design of the OpenScope MZ was a huge engineering undertaking, so the class is 4 hours long, but if you have a topic you’d like to learn about, you can skip to it using the table of contents below the video<\/a>. Here are all the topics covered:<\/p>\n
