avr-vim is a small set of scripts that extracts information from the avr-libc header files to create a Vim syntax file.

Depending on where your avr-libc include directory is, you may need to modify the INCLUDES_DIR variable in the Makefile.

make all will generate a new syntax file from the current avr-libc installation.

The scripts create three AVR-related Vim syntax groups from #defines in the avr-libc header files:

• AVR_ISR for AVR interrupt vectors linked to the Macro syntax group
• AVR_function for #defines that act like functions linked to the Function syntax group
• AVR_define for all other #defines linked to the Define syntax group

Your color scheme will hopefully do something sensible with those, but you can of course customize the highlight for them yourself.

Installation

This repository is a https://github.com/tpope/vim-pathogen bundle. With Pathogen installed, you can easily install avr-vim:

cd ~/.vim/bundle
git clone git://github.com/nottwo/avr-vim.git

avr-vim ships with a Vim syntax file for avr-libc, but you should regenerate it for the version of avr-libc you are working with.

Known deficiencies

Only #defines are extracted, so actual library functions such as the standard library _P variant functions are currently missing.

Future improvements

Break out syntax files for individual parts. If you use a peripheral name that is not present for the declared device, the coloring will show it.
