ChibiOS/RT is a compact and fast RTOS designed for embedded applications. It offers threads, mutexes, semaphores, messages, events, timers, flexible I/O with timeout capability. ARM7, Cortex-M3, AVR, MSP430 and x86 are currently supported.

Nut/OS is based on an intentionally simple RTOS kernel, which provides a minimum of services to run Nut/Net, the TCP/IP stack. Its features include: * Coperative multithreading * ... [More] Deterministic interrupt response times * Priority based event handling * Periodic and one-shot timers * Dynamic memory management Main features of the TCP/IP stack are: * Base protocols Ethernet, ARP, IP, ICMP, UDP, TCP and PPP * User protocols DHCP, DNS, SNTP, SMTP, FTP, SYSLOG, HTTP and others * Socket API * Host, net and default routing [Less]

USBWafer is a small Free Software and Free Hardware USB dongle for various purposes.

Little Realtime Operating System (RTOS). Preemptive kernel designed primary for embedded tiny systems with low RAM usage such as AVR 8bit RISC MCU. Kernel can be run on any POSIX system in cooperative ... [More] mode Also there is version(port) to Microsoft Windows [Less]

The Peggy is an open-source LED display project designed by Evil Mad Scientist Laboratories. Peggy 2.0 is based on an ATmega168 microcontroller and is compatible with the Arduino programming environment.

micro HTTPD server based on modified uIP-1.0 stack, running on 8bit AVR processor and ENC28J60 Project is using parts from the following open source projects: uIP-1.0 minimalistic TCP/IP stack ... [More] for embedded projects by Adam Dunkels uIP version 0.9 port to AVR ATmega32 with ENC28J60 by Jonathan Granade edi87 at fibertel.com.ar AVRopendous hardware to run this project (AVRopendous2-DIP based on Atmel ATmega32U4), donated by opendous Z28J60 Board from MdFLY with Microchip ENC28J60 A similar project, aiming for a more general nic/avr approach is avr-uip Features:Webserver have network configuration page, which allows network parameter change without flashing the mCU The whole project fits into ATMega32U4 device, including standard boot loader Simple CGI scripiting with url parameters decoding have been added to the webserver from uIP-1.0 uIP-1.0 modified to store data in program memory TCP/IP configuration is stored in EEPROM DHCP client is included in standard configuration CompilingSetup Windows or Linux run make Switch the board into bootloader mode by pressing and releasing Reset button while holding HW button run make dfu or copy uhttpd-avr.eep to uhttpd-avr_eep.hex, and then run Flip first flash the uhttpd-avr.hex into main flash memory, and then uhttpd-avr_eep.hex into EEPROM memory, click reset. Setup the LAN to use 192.168.0. subnet, and then use your favorite web browser to access http://192.168.0.2 ( NOTE: it is possible to change default network settings by editing uNetConfigure.h file, parameters UIP_IPADDR - desired IP adress , UIP_NETMASK - network mask and UIP_DRIPADDR - default gateway).

My AVR project code & schematics etc. Starting with Larry the Robot

The aim of the project is to make the gcc based Ada compiler GNAT available for AVR microcontrollers.

Pigmeo is a free multiplatform software project which aims to provide a set of compiler, framework and utilities for developing applications for microcontrollers and embedded systems. Those apps for ... [More] microcontrollers can be written in any .NET language such as C#, Visual Basic .NET, Nemerle, IronPython, C++/CLI... and use any class available in the .NET Framework, plus the classes available in the Pigmeo Framework.

Project is now on hold because there is no one to work on HW. If you are interested send to the project owner.Leddis -LED DISplay- is a moving message display project. The aim of this project is to ... [More] construct a well engineered moving message display and provide it to the open source community. The development of the software for the Leddis will take care to get use of multiple technologies. specially in the interfaces with the real world. Leddis should be heavy with "gadgets" and features, even though a simple project like a moving message display doesn't need to be heavy of gadgets but this will be good to explain using different hardware interfaces and software design problems with that simple application. The moving message display is an emmbedded application, where the development is done using "C". The target for Leddis will be an AVR based MCU using winAVR. Hopefully, Ports to other targets will be available. [Less]
