convert analog signal to digital using rules?

[stin88]

hi. i got a signal that goes from 2volt(high) to around 0,2v(low) in 10ms and repeats with a span around 50ms.. First i thought use a gpio but according to docs but the signal is to weak, got the suggestion to use a level shifter but im not sure how to pick the right one... so now im using the analog input with a voltage divider to lower the voltage to max 1v and now i get readings between 10ms with voltagedrop between 0,4v (high) and 0,2v(low)

now im thinking of using rules to calculate high and low and put the state to a dummy device... and then make a counter out of that.

will this even work?

Triggered by your description of the voltage divider, what configuration of processor & board?

using esp8266-12f chip.. this is my data.. https://i.imgur.com/blP1eFc.png

trying to figure out how i can set rule to count 1 or 0 from the analog value and use another rule to set counter, cant find any example in docs about counters...

on dummy#var1=1 do
if [analogINPUT#value]<500
gpio,16,[dummy#var1]
endif
endon

tried this code with no success

Code: Select all

On System#Boot do    //When the ESP boots, do
TaskValueSet 3,1,0 //set [DummyCounter#counts]=0

endon

On DummyCounter#counts do
   if [feedback#state]<700 //if analog less than 700, add +1 to counter 
     TaskValueSet 3,1,[DummyCounter#counts]+1
   endif
 endon

going to check for a suitable npn or pnp transistor to amplify the signal....
