An extension for lua-periphery GPIO, especially for the RaspberryPi.
Requires lua-periphery: https://github.com/vsergeev/lua-periphery and adds the option to activate pull-up or pull-down resistors when opening GPIO as inputs.
Example:
local GPIO=require"gpio_bcm2708"
local gpio17=GPIO(17, "in", "down")
local gpio7=GPIO(7, "in", "up")
local gpio23=GPIO(23, "in", "off")
local gpio3=GPIO(3, "out")
Futher processing is identical to periphery.GPIO
