#VIC™

VIC™ is a nice syntax that compiles to PIC assembly. For detailed up-to-date documentation read http://selectiveintellect.github.io/vic.

##Building as a user from source

For more details on installation refer: http://selectiveintellect.github.io/vic/install.html

To quickly build something from source:

$ perl ./Build.PL --install_base=/usr/local/
$ ./Build test
$ ./Build install

##Dependencies

This module depends on the following which need to be installed using CPAN. For more details on installation refer: http://selectiveintellect.github.io/vic/install.html

##Testing the Module

If you're a developer, to test you will need to have App::Prove installed:

$ prove -lv t

Another option is to use Build.PL

$ ./Build test

##Vim Syntax

The vim syntax for VIC™ is in share/vic.vim. You can place it in $HOME/.vim/syntax on Linux and OS X and in $HOME/vimfiles/syntax on Windows systems.

##How to write VIC™ programs

Refer http://selectiveintellect.github.io/vic/gettingstarted.html for learning how to write VIC™ programs.

##Compiling examples

The examples are in share/examples folder. To compile the helloworld.vic example you can do the following:

$ ./bin/vic ./share/examples/helloworld.vic -o ./share/examples/helloworld.asm

This will generate the PIC assembly for the VIC™ file.

Details on the examples can be found at http://selectiveintellect.github.io/vic/examples.html.

##Placing vic in your $PATH for Makefiles

Let us assume that your git checkout copy is in $HOME/github/vic then,

$ export VICPATH=$HOME/github/vic
$ export PERL5LIB=${VICPATH}/lib:${VICPATH}/pegex-pm/lib:$PERL5LIB
$ export PATH=${VICPATH}/bin:$PATH
$ which vic

If you're installing it from CPAN or using Build.PL you do not need to set the above.

##Testing on PIC microcontrollers on Linux and Mac OS X

The helloworld.vic test is for the Low Pin Count Demo board from Microchip and uses the PICKit2 programmer to write to the microcontroller P16F690 on the board.

You will need to have gputils installed on Linux or Mac OS X.

For Mac OS X, you may need to use MacPorts to easily install the gputils and gpsim packages.

$ cd share/examples/
$ gpasm -pP16F690 -M -c helloworld.asm -o helloworld.o
$ gplink -q -o helloworld.hex helloworld.o

This will produce a helloworld.hex file which you will have to write to the microcontroller using PICKit2 programmer from Microchip. You could use any other programmer as well as long as you have the right software for it. To write to the microcontroller on Linux or Mac OS X you need to have pk2cmd installed. Refer http://selectiveintellect.github.io/vic/pk2cmd.html for details on that.

If you have pk2cmd installed in /usr/local you will need to set the PATH variable as follows before doing the write to the microcontroller:

$ export PATH=${PATH}:/usr/local/bin:/usr/share/pk2

Before you run pk2cmd on Mac OS X, you will need to set the lsusb command which is available on Linux but not on the Mac but is used by pk2cmd internally.

$ alias lsusb="system_profiler SPUSBDataType"

To write to the microcontroller run the following:

$ pk2cmd -PP16F690 -M -Fhelloworld.hex

To run the test and have the microcontroller execute the code on the Low Pin Count Demo board to turn on the LED,

$ pk2cmd -PP16F690 -T

To stop the test and turn off the LED,

$ pk2cmd -PP16F690

To erase the code from the microcontroller,

$ pk2cmd -PP16F690 -E

NOTE: All the above have been implemented in a GNUmakefile present under share/examples/GNUmakefile.

##Testing on PIC microcontrollers on Windows

For Windows, we currently recommend using the Microchip provided IDE. You can use VIC™ to generate the assembly files which you can then load into the IDE as part of your project and use. For more details refer http://selectiveintellect.github.io/vic/install.html.

If you want to use Cygwin to perform builds using gpasm and pk2cmd you may choose to do that and let us know if you succeed so we can write instructions for other users.

##Recompiling the grammar

This is for VIC™ developers only.

To recompile the grammar into lib/VIC/Grammar.pm run,

$ ./share/rebuild-grammar

or

$ ./share/rebuild-grammar.PL

or

$ perl ./Build.PL
$ ./Build

All of the above do the same thing.
