Custom PID for KM since last DPF regeneration

[jimwhitelaw]

The library doesn't support that type of query using processPID(), but you can use it to get the data you want. Instead, use sendCommand(), and then parse the response in your code. The full response from ELM327 will be available to you in myELM327.payload after calling getResponse().

Include something like this in your loop() method:

    myELM327.sendCommand("22242C");
    if (myELM327.nb_rx_state == ELM_SUCCESS)
    {
        myELM327.getResponse();
        // parse and process the values you want from myELM327.payload
    }
    else if (myELM327.nb_rx_state != ELM_GETTING_MSG)
    {
        myELM327.printError();
    }

IT WORKS.
I used this code:
DPF_KM = myELM327.processPID(34, 9556, 4, 4, 1, 0); //PID 222554; Equation: ((A256)+B)
if (myELM327.nb_rx_state == ELM_SUCCESS)
{
D = myELM327.responseByte_0;
C = myELM327.responseByte_1;
B = myELM327.responseByte_2;
A = myELM327.responseByte_3;
DPF_KM_calc = ((C256)+D);
obd_state= ENG_RPM;
}

and I retrieved the correct data (verified) in Arduino Serial Monitor:
Delimited found.
All chars received: 6225540139
Expected response header: 622554
Single response detected
64-bit response:

responseByte_2: 0
responseByte_3: 0
responseByte_4: 0
responseByte_5: 0
responseByte_6: 0
responseByte_7: 0
Service: 34
PID: 9556
Long query detected
Query string: 222554

So, after conversion, the KM from last regeneration are 313.

Thanks a lot for your support!
