Software

Basic development environment for LPC21xx microcontrollers. It contains makefiles for building your applications and code for booting the processor.

We have also developed a tolpc tool, which can be now used for loading applications to RAM. For flash loading lpc21isp can be used. In future we will include flash programming posibility to tolpc.

Getting the software

Actual source code can be downloaded using a Git tool (you need at least version 1.5.3.4 for submodule support):

 git clone git://rtime.felk.cvut.cz/sysless-lpc21xx.git

If you have an acount on the rtime server, you can use ssh-based access to the repository. If an administrator gave you the right for writing to the repository, you can not only read (pull) repository but also write (push) changes to the repository:

 git clone <login>@rtime.felk.cvut.cz:/var/git/sysless-lpc21xx.git

For the proper work you need to download and configure additional common files:

 cd sysless-lpc21xx
 git submodule init
 git submodule update

Later you can update your repository using the command:

 git pull

and if you see modification of common directory also:

 git submodule update

Browsing of project sources is also possible via GIT web interface.
