[Solved] ERROR: in expansion of macro 'BLYNK_WRITE'

Solved
1

I have my ongoing project with library 0.4.10. I have come across this error now when writing some new code. I have many similar pieces of code but this is what fails:

BLYNK_WRITE(V26) { 
  int value = param.asInt();
  }

but this works:

BLYNK_WRITE(V36) { 
  int value = param.asInt();
  }

I picked the V36 at random (and some others as well to test) to continue with the rest of the project. Any ideas what could be wrong?

Do you have the V26 function twice in your sketch?

It has been a long week… You are right! I didn’t have it in my commented list of Virtual Pins. Apologies!
