In the past 20 years I worked on a huge set of projects.
Here the one I think are useful

ESP8266 VGA OUTPUT

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 …

C64 Kernal and ROM Hacking

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/c64rom9 forks.57 stars.0 open issues.Recent commits: added README, Michael Steil split KERNAL into segments, Michael Steil cleanups; added version byte and signature, Michael Steil …

Georg Rottensteiner C64Studio

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….

Z80 Retro Computing with Arduino

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. …

IoT Async

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 …

Esp8266 Music Machine

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 …
