Creation of a pulsation counter

Community Help With My Project
1

Hello

I try to create a counter showing the number of turns that a screw has turned, and another that increases by 1 when the screw has turned 30 turns
but I don’t know which widget to use, and I don’t know if my program is good

Thank you for your help

Dont use V1 , you can directly use the channel number. Cayenne.virtualWrite(1, Kilos); //virtual pin1
Add #define CAYENNE_DEBUG in your code and see what is the issue in the serial monitor.

Hello
thank you for your reply

I made the changes, but it doesn’t work
I also added the “DEBUG” mias we don’t see anything on the serial
We see the Data on channels 2 and 5 but nothing no for channels 11 and 12

Thanks

Thanks for you help

this should change to CAYENNE_OUT(11)

Hello

thanks for the help

It’s going on, but not everything

for channel 8 data it’s ok, but not for channel 7 (see photo)

What does this print out? Is it a real value?

9

yes, as @adam suggested check what you are getting in the serial monitor.

10

Hello

The serialprint works perfectly but is not transferred (see photos)

20200212_182244
20200212_1822443264×1836 3.45 MB

I just changed today “int Kilos = (countTours / 3)” to
float Kilos = (countTours / 3);
but no change

11

can you share more of the serial monitor output where there is cayenne debug lines.

12

The debug function does not work, because I have no debug information line

see on the photo, I have no other information
the project is shared

13

The problem comes from the variable “kilos” because when I send the variabel “countTours”, it works

but i don’t know what i can change

14

Oops, I thought the problem was with channel 8. You have “Kilos” defined in 2 places. In the loop do not define it again. You are creating a second local variable in loop and it is not changing the global.

15

good catch @adam

16

If I delete “float Kilos” in line 30, it doesn’t compile

if it modifies " kilos = countTours / 3 “the serial print gives” 0.00 "

17

It should be Kilos = (countTours/3); case sensitive.

18

It’s written like that in the program
“float Kilos = (countTours / 3);”

19

the last sketch is back
serial print kilos ok but not in cayenne

You didn’t fix what I told you to. Change float Kilos =(countTours/3); to Kilos =(countTours/3); Has to be exactly as I put here.
