The hardest part of learning x86 assembly in 2013 is finding good tutorials. As the popularity of low level languages decreases the incitement to create fresh up to date tutorials is limited.
At the same time x86 assembly is critical in many security related fields such as malware analysis, vulnerability research and exploit development.
This document was created to address the lack of tutorials in a fast, pedagogical and cheap manner. While it is not a complete introduction, it addresses enough to prepare careful
readers with the necessary knowledge base to be able to decipher non-obfuscated assembly. And it does so within less than thirty pages.
For pedagogical reasons focus is kept to what the reader assumedly knows about C or C based languages (like Java or C#). Hopefully this minimizes the confusion that usually
appears when people are trying to learn a stack based language for the first time.
• We built a framework for microcode reverse engineering
• We reverse engineered substantial parts of the encoding
• We implemented meaningful microprograms from scratch
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Updates to this page will happen frequently. Our blog and social media platforms will be utilized in actionable ways. Specific actions each week noted and shared as part of our all-company “State of the Fruit” notes and all-company meeting. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country adafruit.com/blacklivesmatter
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound.
