push button and http cmd value/state of button

[pw444]

Hya,

i would like to know if and if yes, how to change teh value of a state using rules.

I have one push button define device switch input, push button active low, pullup pn, gpio0, named pb01.

With the followin code,

Code: Select all

// pb01   - gpio 0 - D5
// output - gpio 2 - D3

On System#Boot do
 let,1,0 // future enhancement by VAR
endon


on pb01#value do
  if [pb01#value]=1
    GPIO,2,1
  else 
    GPIO,2,0
  endif
endon

on pb01_on do
  GPIO,2,1
endon

on pb01_off do
  GPIO,2,0
endon

,

it works. pusing button, output is on (by devices, value 1), push again, it's off (by devices, value 0).

now, by off, by devices, value 0
using web:
http://192.168.1.5/control?cmd=event,pb01_on output in on, and by devices, value does not change, remains 0.
i push the button, nothing happens, i push it a second time, and output is off, and value by devices is ok.

Is there a way to change the value inside the rule, so either by physical button or by web - http cmd, the value reflects the action, so after using http, the state / value is correct and pushing the button it works, without having to push twice?

TIA

For each GPIO command you should add a let command.

Thx for answering.

Just let, alone?

example, please?

That's the old way. For LET commands let me get back to you on that if you still want it?

[pw444]

Thx for the answer.

By the examples, old way, a toggle switch (on off) is used. I'm using a push button.

" For LET commands let me get back to you on that if you still want it?", sure!

It's not a physical toggle switch. It's a virtual way of toggling.

[pw444]

Yes, sir, it's virtual toggle. The physical button (which exists), it's a push button.

All i want to is get rid of the need of pushing physically twice after it has been virtually toggled, when the state / value does not change.

If you can be so nice and educate me with the suggested "let" i'll really appretiate it.

By the old way, if there is also a way to have the state / value changed when virtually toggled, i'll also appretiate, as i could not find in the rules docs how to set the value of pb01 (pb01#value), like value=1 or value=0.

Thx in advance.

Did you read the discussions I linked to?

Did you read the discussions I linked to?

yes, i did. and using the old way, i got it. i was asking the new way, with let, as you mentioned, and also asked.

That's the old way. For LET commands let me get back to you on that if you still want it?

but maybe i'm not that smart, in neither post i've found how to set the pb01#value (value velue # of a device) variable to 1 or 0 using rules

[grovkillen]

Ok good. I will get back to you on that one. I'm watching a movie with the family

[pw444]

Ok good. I will get back to you on that one. I'm watching a movie with the family

ok, thank you. look forward for the reply

Code: Select all

On System#Boot Do
 Let,1,0 //on boot make sure the LED is off
 GPIO,2,1 //the LED is set to off (inverted logic)
EndOn

On Button#State Do
  Event,toggleLED
EndOn

On toggleLED Do
  If [VAR#1] = 0
   Event,turnOnLED
  Else
   Event,turnOffLED
  EndIf
EndOn

On turnOnLED Do
  Let,1,1
  GPIO,2,0  //remember that this example uses onboard LED which is using inverted logic
EndOn

On turnOffLED Do
  Let,1,0
  GPIO,2,1  //remember that this example uses onboard LED which is using inverted logic
EndOn

Now you can use these three (event) commands:
toggleLED if LED is on it will be turned off, if LED is off it will be turned on
turnOnLED if LED is on it will not change, if LED is off it will be turned on
turnOffLED if LED is on it will be turned off, if LED is off it will not change

Ok, thank you.

My doubt was regarding the use of let on states.

Last sunday, i had the follwoing code:

Code: Select all

// pb01   - gpio 0 - D5
// output - gpio 2 - D3
// boots off

On System#Boot do
 let,1,0
// GPIO,2,0
endon

on pb01#value do
   gpiotoggle,2
   if [VAR#1]=0
    let,1,1 // state on
    // publish light on
   else
    let,1,0 // state off
    // publish light off
   endif
endon

on pb01_on do
  GPIO,2,0
  let,1,1
  // publish light on
endon

on pb01_off do
  GPIO,2,1
  let,1,0
  // publish light off
endon

on pb01sw do
  gpiotoggle,2  
  if [VAR#1]=0
    let,1,1 // state on
    // publish light on
   else
    let,1,0 // state off
    // publish light off
   endif   
endon

i was not understanding the let use, but your example shows it.

Thx a lot.
