Hello Lua

After downloading the lua firmware into LinkIt ONE, use a serial terminal like putty to access lua shell.

Blink

pinMode(13, 1)
while true do
  digitalWrite(13, 1)
  msleep(1000)
  digitalWrite(13, 0)
  msleep(1000)

Note: while loop will make lua shell stops reading users' input, a restart is required to try new things.

or use a timer

pinMode(13, 1)
d13 = 0
function blink()
  d13 = 1 - d13
  digitalWrite(13, d13)
end
t0 = timer.create(1000, blink)
