It’s a good project for learning about the fundamentals of machine code, and will also appeal to people who like programming challenges. The simplified machine code, called MINIL, is designed to be easy to learn and understand. It’s similar to the Little Minion Computer used in some universities to teach students about machine code. The same method could be used to emulate other simple processors, such as the SC/MP, 6800, 8080, or 6502.
Once you type in the opcode the Tiny Machine-Code Monitor displays the assembler statement alongside it on the display, allowing you to check that it’s what you intended. Because you enter the opcodes in hexadecimal it avoids the need for a full alphanumeric keyboard, while giving you the advantage of seeing the assembler program on the display.
The project is based on the Microchip/Atmel ATtiny85, a small microcontroller with alot of capability (used in the first Adafruit Trinket and Gemma boards).
(Ed. nice to see work by a fellow 6800 era programmer)
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
