I've written up how I extracted some firmware from the RF controller and where I am currently at. It's interesting and I feel as though I am pushing my own limits. Learning and discovery is always rewarding 😃

These came out so good. #fpga

I love this community. Seriously, we have so many giving up their time to create knowledge and information for free, for everyone to learn and grow.

SiliWiz helps you get a basic understanding of how semiconductors work & are manufactured at a fundamental level.

There's also a bloody good document available at: https://docs.google.com/document/d/1H3jA7guvXT7toEvUObOQ1viQ6Qz_QSGDiJ5OBS2pDEI/edit?usp=sharing

There's no excuse anymore, we are in a golden age of accessibility and free information to change and grow.

Kudos to @matthewvenn

In FPGA development, resets are crucial for synchronized systems but using them correctly can be a challenge.

Join us in an interview with our FPGA engineer Carl, and get the inside scoop on what role resets play in FPGA design and why they require careful handling: https://youtu.be/8vvS05V1YL0

In episode ( https://embedded.fm/episodes/404 )Reinhard Keil talked to us about CMSIS among other things. Here's an excerpt:

CW (00:18:35):
You've mentioned CMSIS a couple of times and I think it's really, really cool, but I don't think we've described what it is. Could you describe what CMSIS is briefly?

...

Just a reminder of a few great tools for firmware unpacking, repacking and
analysis

We're off this week. However, there are a plethora of shows you can listen to in the meantime.

Here's an informative one( https://embedded.fm/episodes/404 ) from the past if you're looking for suggestions.

Reinhard Keil joined Chris (@Stoneymonster) and Elecia(@logicalelegance) to talk about creating the Keil compiler, the 8051 processor, Arm’s CMSIS, and the new cloud-based Keil Studio IDE.

Today, I used a logic analyzer to look at a signal I found on my Smart TV remote control.

@pipelinec Interesting, but looks ... I dunno. Simultaneously too high level and too low level. This is usually the type of diagram I like to make in Visio. It contains things as a HDL designer I care about deeply, clock domain handling, number scaling, rapid access and mention of control registers, etc.

@remi I just came across this #HDL GUI/block diagram tool today. I'm not a block diagram fan - but its nice there appears to be an ~open option https://research.tuni.fi/system-on-chip/tools/ of sorta - something something has #python api too? #eda #fpga #soc

Thank you John, for the #Hacker #Walkthrough on #TryHackMe
Day 19, #AdventOfCyber2022 #HardwareHacking challenge.

Your presentation was the best I've seen! You & THM made a sometimes challenging subject so easy to understand - #Quality #Learning !

I will be keeping an eye out for more of your presentations.

Your delivery was crystal clear!

Good that I was able to find you out here as I am a recent migrant from birdsite

Cheers 🏴‍☠️​

@North this but every email I write

@shawnhymel Hi Shawn, how are you doing? Nice to meet you again here🙂
