[KL46Z] Magnetometer MAG3110 interrupt

rafcio100 — Sat, 09 Dec 2017 20:10:00 GMT

I have a problem with configuring MAG3110 interrupts. The PTD1 pin is always HIGH.

#include "mbed.h"
#include "MAG3110.h"
MAG3110 mag(PTE25, PTE24);
Serial pc(USBTX, USBRX);
MotionSensorDataCounts mag_raw;
InterruptIn mag_interrupt(PTD1);

void flip() {
    mag.getAxis(mag_raw);
    float x;
    x = ((float) mag_raw.x) / 10.0f;
    pc.printf("Mag x=%4.1f\r\n", x);
    wait(1.0);
}

int main(void){
    pc.baud(9600);
    mag.enable();
    mag_interrupt.rise(&flip);
    while(1) {
      sleep();
    }
}

Hi Rafal Jablonski,

About the MAG3110 interrupt usage, you need to follow these step:

Please check it on your side, do you finish these step?

If you still have question after the test, please tell me the updated information.

Wish it helps you!

Have a great day,
Kerry

Hi Kerry Zhou,

I was finished this steps before I wrote that post, but it doesn't work. Pin INT is always HIGH, even when I read 0x01 OUT_X_MSB register.
