I am a beginner I'm not sure if my use of processPID is correct. I don't quite understand the RXD part of how to use it with processPID.
RXD: 3008
#include "ELMduino.h"
#define DEBUG_PORT Serial
ELM327 myELM327;
int nb_query_state = SEND_COMMAND; // Set the inital query state ready to send a command
void setup()
{
DEBUG_PORT.begin(115200);
Serial2.begin(115200, SERIAL_8N1, 16, 17);
if (!myELM327.begin(Serial2, true, 3000))
{
Serial.println("ELM327 device couldn't connect to ECU.");
while (1);
}
Serial.println("Connected to ELM327");
// Set a custom header using ATSH command.
myELM327.sendCommand_Blocking("AT SH 7E1");
}
void loop()
{
float temp = myELM327.processPID(34, 4119, 1, 1, 9 / 5, -58);
if (myELM327.nb_rx_state == ELM_SUCCESS)
{
Serial.print("Temp: "); Serial.println(temp);
}
else if (myELM327.nb_rx_state != ELM_GETTING_MSG)
myELM327.printError();
}
I want to read the transmission fluid temperature in my Subaru XV, but I don't know how to take the values. How to put it in the reading process to be complete?
