IST8310 Arduino

This is a simple Arduino library to get magnetometer values from an IST8310 compass sensor over I2C. The code is almost entirely based on https://github.com/dayaftereh/rocket

This example has been tested on Teensy 4.0 board connected to the Holybro F9P Helical module. IST8310 has an I2C address of 0x0E. This can be changed in IST8310.h.

Example code:

#include "IST8310.h"

IST8310 ist8310;

void setup() {

  Serial.begin(57600); 
  while (!Serial);   

  Wire.begin();

  Serial.println("Trying to setup IST8310");

  bool success = ist8310.setup(&Wire, &Serial);
  if (!success) {
      Serial.println("Failed to setup IST8310");
  }
  ist8310.set_flip_x_y(true);
}

void loop() {

  bool success = ist8310.update();
  if (!success)
  {
      Serial.println("Failed to update IST8310");
  } else {
      Vec3f* mag_latest_val = ist8310.get_magnetometer();

      Serial.printf("Mag (x, y, z): (%f, %f, %f)\n", mag_latest_val->x, mag_latest_val->y, mag_latest_val->z);
  }
}

Example Output:

12:31:24.615 -> Mag (x, y, z): (49.000000, -23.000000, 139.000000)
12:31:24.615 -> Mag (x, y, z): (49.000000, -23.000000, 139.000000)
12:31:24.615 -> Mag (x, y, z): (49.000000, -23.000000, 139.000000)
