How to detect what device is running, turtle or pc or pad?

Hello, I'm trying to automatic run a script on startup, and dispatch to different logic branch according to the device type. Following is a peice of code for demo, which cannot successfully run:

local dt = os.getDeviceType()
if dt == "turtle" then
    runTurtleScript()
elseif dt == "pc" then
    runPCScript()
elseif dt == "pad" then
    runPadScript()
end

I have checked the API doc but doesn't find such an API similar to `os.getDeviceType()`

Is there any solution to implement such a function?

Now I know that I can check if current device is turtle via `if turtle == nil`, but it seem not easy to distinguish a PC and a Pad.

You can distinguish a PC from a pocket pc by checking for "pocket" and you can check for a command computer using "commands" just like you do with "turtle". So your getDeviceType() function might look like this:

local function getDeviceType()
   if turtle then
    return "turtle"
  elseif pocket then
    return "pocket"
  elseif commands then
    return "command_computer"
  else
    return "computer"
  end
end
local dt = getDeviceType()
if dt == "turtle" then
  runTurtleScript()
elseif dt == "computer" or dt == "command_computer" then
  runPCScript()
elseif dt == "pocket" then
  runPadScript()
end

@Luca_S Thank you! this reply is very helpful :)/>
