read Speed

[cuongcoco]

hi
i want read speed by obdIIUART and print it to Serial monitor
my code is
#include <OBD2UART.h>

COBD obd;

void setup()
{
// we'll use the debug LED as output
pinMode(13, OUTPUT);
Serial.begin(115200);
// start serial communication
obd.begin();
// initiate OBD-II connection until success
while (!obd.init());
}

void loop()
{
int SPEED;
if (obd.readPID(PID_SPPED, SPEED)) {

Serial.println(SPEED);

}
delay(500);
}

but my result is
ATIATZATE0ATH0010D0100012001400160
010D50
010D50
010D50
why it happend? i only want "50" as speed
please help me

Hi, I think your error can be that you have mispelled PID's name, you need to write PID_SPEED instead of PID_SPPED, so wrong code would see like:

if (obd.readPID(PID_SPEED, SPEED)) {
    Serial.println(SPEED);
}

I hope this can help you.
