Examples

gpio.setup(7, 0, gpio.PULLUP)
gpio.setup(12, 0, gpio.PULLUP)
gpio.setup(13, 0, gpio.PULLUP)
gpio.setup(14, 0, gpio.PULLUP)
local sm =  statem.create()
            :gpio_set(7, 0) -- gpio Set to Low
            :usleep(10)     -- Dormancy 10us
            :gpio_set(7, 1) -- gpio Set to High
            :usleep(40)     -- Dormancy 40us
            :gpio_set(12, 1) -- gpio Set to High
            :gpio_set(13, 1) -- gpio Set to High
            :gpio_set(14, 1) -- gpio Set to High
            :usleep(40)      -- Dormancy 40us
            :gpio_set(7, 0) -- gpio Set to Low
            :finish()

-- Execute it, and the background execution will be supported later.
