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!
