OBDII Polling Timer
Posted: Thu Dec 25, 2014 1:06 pm
I am trying to improve my OBDII tool polling timer. Simply, I want to take a group of text strings (PID values selected by the user) and be able to cycle through each one and send it through the COM Port module to the OBDII bluetooth adapter.
I put together a version using a portion of the OBDII tool PID value selection section together with GET At String and advanced counter. The reason I am doing this is to avoid using the Select primative that I used in my first prototype OBDII tool as I believe it causes miss timing issues during PID value polling.
My question is: when creating an "array" of the strings (PID values), why do I have to use a NL at the start so the Get At will locate it at position 1? Am I missing something? I have tried using the String Array, looked at the Queue and Stack modules and other ways of attempting to do this but could not get it to work. Is there a better way of approaching this?
