Piklab is an integrated development environment (IDE) for applications based on Microchip PIC and dsPIC microcontrollers similar to the MPLAB environment. It integrates with several compiler and ... [More] assembler toolchains (like gputils, sdcc, c18) and with the GPSim simulator. It supports the most common programmers (serial, parallel, ICD2, Pickit2, PicStart+), the ICD2 debugger, and several bootloaders (Tiny, Pickit2, and Picdem). It was started from Pikdev sources: http://pikdev.free.fr [Less]

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

Firmware for Cypress' EZ-USB (AN2131) device that lets you use keyboards, mice etc. as USB compliant Human Interface Devices.

Micropendous boards are Open Hardware Development Boards for Atmel's USB AVR Microcontrollers with a Free and Open Source Software (FOSS) hardware, firmware, and software development platform.

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.

LUFA (formerly MyUSB), the Lightweight USB Framework for AVRs. This project is an open source, MIT Licensed USB stack for the USB enabled 8-bit AVR microcontrollers. For more information, visit the ... [More] project home page from the links bar to the right. Official stable releases are available from http://www.fourwalledcubicle.com/LUFA.php - the SVN repository here is a synced mirror of the LUFA development repository used by the author and is thus highly unstable and should be used for preview purposes only.

[More] POV is an electronic LED bar to attach on bicycle wheels. When riding the bicycle, the LED bar will draw with light, text messages and image animations. Custom text messages and animations will be drawn on a PC software and downloaded using an USB cable. Goals of the projectcreate a Free/Open hardware, firmware and software LED POV for bicycle wheels; easy to use for non electronics technician people; find some company that wants to sell PCBs, kits or final assembled product; use only Free Software tools as possible, like CAD software for PCB design, C compiler for MCU firmware, etc; open to improvements and new ideas from community. Your participationBecause hacking is fun and projects are like life, always evolving, If you have any ideas, If you think you can improve the project, If you want to say something, please leave a message on the discussion group. This project is a work in progress, It's an effort to improve actual bicycle LED POVs as the SpokePOV from Ladyada. There is room for a lot of improvements as the project involves different areas as: mechanics; electronics; software; LED art; animations; demos. DescriptionBicycle LED POV is an electronic LED bar to attach on bicycle wheels. A magnet is also attached on a fixed part of the bicycle (as example, the fork), so the hall effect sensor mounted on the Bicycle LED POV can detect each full rotation of the wheel. Bicycle LED POV consist of mainly three different parts: Hardware; Software and Firmware. Hardware HaRdware consist of an electronics printed circuit board with LEDs and a few components as a microcontroller unit, a memory to hold the text messages and image animations, an USB connector and 2 NiMh cells. See more information on HaRdware page >> FirmwareFiRmware is the software that will be inside the MCU, it will configure the hardware system to work as needed. See more information on FiRmware page >> SoftwareSoFtware is a PC Free Software program to send text messages and image animations to the HaRdware. See more information on SoFtware page >> [Less]
