32bitmicro build environment

Wednesday, 16 December 2009 10:59 administrator

32bitmicro build environment (32bitMBE) is a part of the 32bitmicro open source collection of code and tools for 32 bit microcontrollers.

32bitMBE uses simple project level makefile to specify all of the sources, configure target MCU, OS and host tools.

32bitMBE is licensed under New BSD License.

See the example makefile for CMSIS based application targeting LPC1768 Makefile

Project is hosted on Google code and can be anonymously check out using Subversion from source repository.

# Non-members may check out a read-only working copy anonymously over HTTP.
svn checkout http://32bitmicro.googlecode.com/svn/trunk/ 32bitmicro-read-only

Protothreads

Saturday, 19 December 2009 09:26 administrator

Protothreads are implementation of stackless cooperative threads very well suited for memory constrained systems. Protothreads allow implementation of complex state machines in event -driven applications and systems.

Invented by Adam Dunkels, protothreads implementation in C makes use of Duff's device.

Protothreads library is released as open source under BSD-style license

Protothreads version 1.4 are available in 32bitmicro distribution.

Wavenis

Wavenis is a two-way wireless connectivity platform for applications that need to manage small amounts of data with low radio traffic, ultra-low-power management and high reliability. Wavenis-enabled devices are already at work in a variety of AMR (automatic meter reading), AMI (advanced meter infrastructure), home and building automation, industrial automation, medical and environmental UHF-active long-range RFID applications.

Operates in license-free ISM 433 MHz, 868 MHz, 915 MHz frequency bands.
