FileSystem is an OPENSOURCE program for advanced disk management with built-in drivers for PATA IDE Hard Disks and DVD/CDROM Drives, USB Mass Storage Drivers. Implemented file systems : FAT32 / ISO9660 / EXT2. It can be compiled for DOS, LINUX, WIN32
Collection of embedded softwares to control a telescope mount.
EQ Track purpose is to provide amateur telescope makers (ATM) with electronic board schematics and embedded software to control their telescope mount via stepping motors. EQ Track comes in different "flavors" : - "Basic" controls the right ascension and declination motors of an equatorial mount. - "Go To" controls the motors of a mount in any orientation (ie. equatorial, altazimuth, alt-alt), to point and track equatorial coordinates.
A Interface to adapt modern SD Card to the old MSX computers
This is an open source project that aims to create a MSX cartridge that acts as a old disk drive interface but in fact it will be accesing a modern SD Card. For the MSX it will be as if there is a magnetic disk drive with a real magnetic disk but for real it will be accessing a .dsk file inside a sdcard. Development tools used are: - Kicad version 2013-07-07 - Microchip XC8 v1.21 (free mode) - Micrchip MPLAB X IDE v1.90 - Altera´s Quartus Web Edition 11.0 UPDATE 2014-11-05 =============== Now it is working and the SVN repositories has it all: Schematics, PCB layout, firmware for the CPLD and the firmware for the MCU. But you have to download by your own the firmware for the 49F010 on the internet.
Atmel AVR 8bit Microcontroler Tests and Tools
- A collection of tools for programming an Atmel AVR 8bit Microcontroler. - Circuit decriptions for Atmel AVR 8bit Microcontrolers used for testing.
Play multiplayer games from multiple keyboard
KBDMapper is a hardware based keyboard multiplexer that allows you to play keyboard-based multiplayer games with more comfort. By splitting control keys for each player to each separate keyboard, allows each player to choose his/her own control keys without worrying that they will conflict with each other. Currently KBDMapper allows two keyboard to be connected together. This project works with PS/2 keyboards and present itself to PC as a single PS/2 keyboard.
A hamradio DSP tranceiver on a Cortex-M4 MCU (STM32F4xx)
M4DSP is a QRP (low power) hamradio digital signal processing (DSP) tranceiver using a comprehensive yet powerfull Cortex-M4 MCU from STMicroelectronics. The main goals are: low cost, low power consumption, IPhone-like size & weight, QRP CW RX & TX, SSB/AM/FM RX-only, digital modes by demand, GUI with TFT + touchscreen, waterfall spectrum, CAT communication link via low-speed USB, pure SDR-like mode via high-speed USB, one or more hamradio bands (160-10 m), optional support for general coverage RX (0-30 MHz).
The control kernel for any small control system
Mini Control System Kernel is a library developed using C (avr-gcc) and avrassembelr. This library including the drivers for hardware and adds the abstract layer to make it easier to work with perephirical devices. The circuit and live example will be added later.
An open hardware and software platform, Octobits attempts to recreate the aesthetics of the early eight-bit computer age using cheap, powerful, and readily available modern components.

cMIPS - an FPGA ready VHDL model for 5-stage pipeline, MIPS32r2 core
This project was moved to https://gitlab.c3sl.ufpr.br/roberto/cmips The code here is no longer up to date. The VHDL model mimics the pipeline design described in Patterson & Hennessy's book (Computer Organisation and Design) and is an almost complete implementation of the MIPS32r2 instruction set. The TLB and assorted control registers will be included soon (as of fev 2015). The model was synthesized for an Altera EP4CE30F23. The model uses up 15% of combinational blocks and 5% logic registers.
