README

Tcl wrappers for Gordon't WiringPi Library

Uses Gadgetoid's wiringpi.i, modified to remove explicit paths and use the version of WiringPi installed on the system.

You will need swig and tcl-devel installed.

To build, just run:

./build

And the Tcl extension will be built and installed to the first available directory in Tcl's auto_path

Just add "package require wiringpi" at the start of your tcl script to use it

Global variables are created to match some of Gordon's #defines:

pinMode:
INPUT, OUTPUT and PWM_OUTPUT

digitalWrite:
LOW and HIGH

The following Tcl commands are also defined for convenience:

mode <pins> <mode> : calls pinMode to set the mode for each pin in a list of pins
on <pins>          : Sets each pin in a list of pins to HIGH
off <pins>         : Sets each pin in list of pins to LOW

flash <pins> [delay 100] [repeat 1] : Set the pins HIGH and LOW with an optional delay (default 100ms) and optional repeat

Enjoy!
