In the past 20 years I worked on a huge set of projects.
Here the one I think are useful
This is a VGA library for ESP8266. To use this library you need only 1 resistor and one DSUB15 connector. VGA signal generation based on https://github.com/hchunhui/esp-vga (thanks for your awesome works). [….] The library implement a 512x480px framebuffer with 1bpp, where each pixel is stored as a single bit. The framebuffer is stored inside RAM and require …
The first draft of my book is here! Take a look to http://8bit.gioorgi.com/
Hi all! I decided to write a book called “8-Bit Computers: Retro computer history in the ’80”. It is my first book on this topic, so I need you comments & advices! A small extract is right here for download. You will be able to buy the Kindle edition for little as € 0,99 by …
Esp8266 is the super cheap chip which can run Micropython. You can buy it on Amazon for as little as €8 or less, and as little as $5 or less on Bangood/AliExpress. The ESP8266 (ESP-12E spec) has a 4MB Flash RAM and about 96KB of RAM. One nice thing is you can use an async …
Michael Steil just published a repository you can actually USE to hack C64 Kernal and ROM. A nice idea you can play with using VICE emulator… Commodore 64 BASIC and KERNAL Sourcehttps://github.com/mist64/c64rom11 forks.58 stars.0 open issues.Recent commits: added README, Michael Steil split KERNAL into segments, Michael Steil cleanups; added version byte and signature, Michael Steil …
Ok this is a bit embarassing! Even in 2019, there is a IDE for C/64 which is still mantained! C64 Studio is a full .NET IDE which can connect to [Win]Vice for debugging. It seems Deutsche guys are very strong on C/64 Developmenet on these days….
When I was young I was able to play with my Vic20/Commodore64. I learned to love programming with these small 8-bit *real* computers. I was between 11 and 12 years old, and just learning basic English, with only a data-casette to store my stuff. Now my son is 9 years old, and I was unable …
Org-mode is an Emacs mode for keeping notes, maintaining To-do lists, doing project planning, and authoring with a fast and effective plain-text system. Node.js is a event-based server for the V8 JavaScript Engine. So Org Mode Parser for Nodejs is a parser for reading org-mode files. Follow OrgMode updates and news clicking on this link …
Paleotronic’s 12 Years of Retro-Christmas Year One: 1980 – Paleotronic Magazine A sticky post for Dicember 2018
The ZilogZ80 CPU is an 8-bit based microprocessor. It was introduced by Zilog in 1976 as the startup company’s first product. The Z80 was conceived by Federico Faggin in late 1974. The Z80 was software compatible (!) with the Intel 8080 machine language. It added several extensions and was the heart of the ZX Spectrum. Zilog Z80 is the chip who powered half of the ’80 microcomputers. …
After some years in IoT, I tried a bunch of different platform like esp8266 but Arduino remains a must. Simple reason to choose it for your first (or second :) IoT project: Arduino works at 5V and can accept as input voltage 7-12V, but with limit up to 20V (avoid it! :).This mean you can …
UPDATED and BUGFIXED! MicroPython Repl command line is very nice, because you can telnet to the chip and read-and-evaluate python code. It is a great way of learning embedded IoT. The bad thing you cannot copy file while it is running, so experimenting get bad. Also an automatic module update would be a very nice thing to …
Qualche mese fa avevo sviluppato una applicazione IoT per misurare la temperatura e spedire i dati ad una coda mqtt. Poi c’era uns server che colelzzionava i dati. Totale: tre server, con tre punti di fallimento ma architettura molto “cool” In effetti però la potenza dei moderni chip embedded è tale che è possibile implementare …
After months of esp8266 experimentation, I “just” discovered this little chip has also a I2S Audio digital interface. To discover it you must install the Arduino IDE adapter and code directly in C++ (brr, ok not a breeze but not boring like Java :) I2S is a digital protocol to send your digital music to …
Arduino is a great hardware for a lot of reason: easy to use, difficulto to break, it is a very solid 5-Volt board. But it a way too much and it has a very limited amount of RAM. So I started exploring other more “different” solutions. I need an economy chip with some RAM …
