Second ones way cleaner

Code: Select all

function input_change1(state)
    log(state)
    state = not state  
    log(state)
end
I knew there must be a cleaner way - a bit more boolean, it works this time though :D :roll:
So where do I place this snippet of your code in the code that Keith gave me today?

It looks pretty clean to this greenhorn...
Keith did tell me today that there are many things in LUA that the AM developers did not implement in Air Manager. Maybe what you are trying to do is one of those omitted capabilities.
Naw, its just that I use C++ (Arduino flavoured) all the time. As said, I don't use the AM flashed arduinos of any kind, all direct comms for any hardware so never use the built in stuff at all.


as for placement, just lose both of those you have - comment all that out and put the code below in there instead. it should be logical ? he said haha

Code: Select all

-- create output
outp_id = hw_output_add("My output",false)

function input_change1(state)
    log(state)
    state = not state  
    log(state)
    hw_output_set(outp_id,state)
end

-- create input
position_1 = hw_input_add("My input 1", input_change1)

Sorry Joe,

This is what I am getting now....each time I cover the sensor I get True False ...False True....True False....ad infinitum...the LED never activates now.
Oh well, maybe some other day it can get sorted out. It's time for me to grill up my dinner....

Check the post just before your last, you are missing a line of code,... :shock: ;) the bit that controls the led.

Also, the true false false true true etc is correct for the log output as it is showing the entry and change state. Just remove the second log line if its confusing.

As for what happens then I have no idea as i dont have the sensor .. is the output pusled or constant? Anyway, the output in the console is correct for the 2 log lines, as said, remove one to make it easier to read.

Yes sir, I was just posting that I found that omission.

Joe,

It works as it should now. The LED lights up when I cover the sensor as it should. Thank you for all your expertise.

Don't you love it when a plan comes together?

Hi,

Sorry Kirk. I had a short nap. Just add a not to swap the output state.

I see Joe assisted

Code: Select all

-- Create a new output 1
led1 = hw_output_add("My output led 1", true)

-- Create a new input 1
hw_input_add("My input 1",function(state)  
  hw_output_set(led1, not state)
end)
---------------------------------------------------------------
-- Create a new output 2
led2 = hw_output_add("My output led 2", true)

-- Create a new input 2
hw_input_add("My input 2",function(state)  
  hw_output_set(led2, not state)
end)
---------------------------------------------------------------
-- Create a new output 3
led3 = hw_output_add("My output led 3", true)

-- Create a new input 3
hw_input_add("My input 3",function(state)  
  hw_output_set(led3, not state)
end)
---------------------------------------------------------------
-- Create a new output 4
led4 = hw_output_add("My output led 4", true)

-- Create a new input 4
hw_input_add("My input 4",function(state)  
  hw_output_set(led4, not state)
end)

Yea Keith,
He helped out. It's all working now. The more I learn the more I dont know.
