One time lua scripts.

[mrpraline]

Hi,

I'm having trouble understanding 'one time scripts'.

I have some basic lua experience and I've googled for lua script examples and so far I found only mix and telemetry scripts. Together with what's in the reference manual I believe I have a basic understanding how to implement those. However one time scripts seem are a mystery to me.

The reference guide is has a single page on one time scripts and no examples. It seems like the only way to invoke them is through executing them directly from the SD card. I really don't know how to start such a script from 'a specific radio function or when the user selects them from a contextual menu' as it is written in the reference guide.

It seems to me like they should look more or less like wizard scripts, but I can get even the simplest script working.

I tried this as a 'hello world' example:

Code: Select all

local function run(e)
  print("ḧello world")
end
return{run=run}

I also tried

Code: Select all

lcd.drawText(1, 0, "Hello world", 0)

instead of the print()
.
But all I get is a 'Script syntax error'

Does anyone know of a simple example of a 'one time script' and how to invoke them?

You have examples in the wizard, the S6R script, the crossfire script (the last 2 for 2.2, but you didn't specify a version).

Looks like you're just missing a "return 0" in your function. print() puts out things on the debug serial port, you want lcd.drawText() to actually display on the screen.

Thanks!
I missed that.
So my guess that they are more or less the same as wizards is correct.

(BTW I'm on 2.1.9)
