gpio module renamed (back) to pio romfs Lua examples refactored to work with pio module examples were _not_ tested after renaming gpio to pio (but should be ok) 2009-03-12 21:06:14 +00:00			`local pio = pio`
Pong example remorphed for a require() / module () scheme. It now illustrates how to create and use a module in Lua for eLua. An LM3S platform-dependend module is created, exposing it's buttons, leds and offering some utility functions. 2008-12-08 19:39:47 +00:00
