ucdev is my github repository: http://www.github.com/a-v-s/ucdev.
It contains an environment for microcontroller development. It contains many submodules containing peripheral libraries, or SDKs, or whatever a particular manufacturer calls them, for various microcontrollers, as well as Makefiles and other scripts to aid embedded software development.
This page is a work in progress. I’ll add details soon. (No promises when, as all pages on this site are on my TODO list)
