Here's an example with the Madgwick library that I tested with the Processing visualizer sketch in the Madgwick folder. It's delivering pretty good results, someone else might want to test it:
#include <Arduino_LSM6DS3.h>
#include <MadgwickAHRS.h>
// initialize a Madgwick filter:
Madgwick filter;
// sensor's sample rate is fixed at 104 Hz:
const float sensorRate = 104.00;
void setup() {
Serial.begin(9600);
// attempt to start the IMU:
if (!IMU.begin()) {
Serial.println("Failed to initialize IMU");
// stop here if you can't access the IMU:
while (true);
}
// start the filter to run at the sample rate:
filter.begin(sensorRate);
}
void loop() {
// values for acceleration & rotation:
float xAcc, yAcc, zAcc;
float xGyro, yGyro, zGyro;
// values for orientation:
float roll, pitch, heading;
// check if the IMU is ready to read:
if (IMU.accelerationAvailable() &&
IMU.gyroscopeAvailable()) {
// read accelerometer & gyrometer:
IMU.readAcceleration(xAcc, yAcc, zAcc);
IMU.readGyroscope(xGyro, yGyro, zGyro);
// update the filter, which computes orientation:
filter.updateIMU(xGyro, yGyro, zGyro, xAcc, yAcc, zAcc);
// print the heading, pitch and roll
roll = filter.getRoll();
pitch = filter.getPitch();
heading = filter.getYaw();
Serial.print("Orientation: ");
Serial.print(heading);
Serial.print(" ");
Serial.print(pitch);
Serial.print(" ");
Serial.println(roll);
}
}
Updated the madgwick example to use handshaking, and added a p5.js visualizer sketch that works with it: arduino sketch with handshaking p5.js visualizer
Here's an update on the p5.js visualizer. Added some content to explain it.
hello,
I am Tanmay khabia from IIIT Hyderabad. I have worked on various sensors and uses them for various IoT projects.
I wish to work on this issue as a GSoC project.
what is meant by six faces?
which direction are we tapping from on the sensor?
thank you
Six faces means six possible orientations of the board. See https://www.arduino.cc/en/Tutorial/Genuino101CurieIMUAccelerometerOrientation for an example of it.
please guide me if you want further improvement in the pull request.
Hey @sandeepmistry :)
For task 3- Gyroscope as a knob, rotating around the Z axis Do we need something like- https://www.youtube.com/watch?v=vSKEH0FwhUE
Just instead of controlling a servo via the same, do we need to values on Serial Monitor (and keep things simpler) to get orientations as we move our knob (LSM6DS3).
