Display Link

The Display Link connects to and uses any Computer Bus as a display source. From there, the computer can manipulate the output of the Display Link such as cursor position, line clearing, and writing to the display target.

This is an example of how to access the device.

local d = require("devices")
local link = d:find("display_link")
link:setCursorPos(1, 1)
link:write("This is OC2R: Create!")
