    I made a simple arduino library to parse binary data from a UM7. It works well with the Arduino Due, but it should also work with an Arduino Mega.

    https://github.com/mikehoyer/UM7-Arduino

    Currently it only parses binary data packets from the UM7 for roll/pitch/yaw. I can add more functionality if anyone is interested in the project.

    Thanks for sharing! I’m sure that others will appreciate the availability of Arduino support for the UM7.

    Please. Send me the skecth and conector with arduino due board.
    I can not read data for serial port using the arduino due board.

    Thanks for all.

    Configure the UM7 to send binary Euler angle packets at 115200 baud using the CH Robotics serial interface.

    http://www.chrobotics.com/serial-interface

    Connect the RX pin on the UM7 to TX1 (pin 18) on the DUE
    Connect the TX pin on the UM7 to RX1 (pin 19) on the DUE

    That’s it! I’ll add these comments to the example sketch.

    Thanks,
    Mike

    Thanks for sharing, actually i need to print data via serial to PC , i need (Roll and pitch angles,Yaw angle,Roll and pitch angle rates), you code works fine but when i add following statements, the Arduino Mega2560 doesnt send data to PC …

    #include <UM7.h>

    UM7 imu;

    void setup() {
    // put your setup code here, to run once:
    Serial.begin(115200);
    Serial3.begin(115200);
    }

    void loop() {
    // put your main code here, to run repeatedly:
    // put your main codeo here, to run repeatedly:
    if (Serial3.available() > 0) {
    if (imu.encode(Serial3.read())) { // Reads byte from buffer. Valid packet returns true.
    //roll, pitch, yaw, roll_rate, pitch_rate, yaw_rate;
    Serial.print(“roll = “);
    Serial.println(imu.roll);
    Serial.print(“pitche = “);
    Serial.println(imu.pitch);
    Serial.print(“yaw = “);
    Serial.println(imu.yaw);
    Serial.print(“roll rate = “);
    Serial.println(imu.roll_rate);
    Serial.print(“pitche rate = “);
    Serial.println(imu.pitch_rate);
    Serial.print(“yaw rate = “);
    Serial.println(imu.yaw_rate);
    }
    }
    }

    Why not connect the UM7 directly to the PC? Just port the binary parser code to run on the PC, should be straight forward to get the same code running in C# or C++.

  • #941

    Hi Mike, Do I need polling the UM7 to initiate a serial read of one or more registers (to tell the device that it will be a read operation), or the code is configured for only read of the incoming packets?

    Helo sir. !
    I purchased um7 lte orientation sensor. I have done the calibration of that sensor. Now i could not able to make code that how to receive roll,pitch,yaw values serialy in arduino due controller. Can you please help me . I have very limited time. Thanks.
    Thanks.

    Hi,

    is it possible to change the library so i can get the data from the internal temperature Sensor?
    Everything else works great.
    Thanks for the library.

    Hello… I use um7 with arduino mega.

    why I get this angle values. values not between -360 and 360. what is problem ?

    yaw angle: 4214
    roll angle: 16437
    pitch angle: 777
    yaw angle: 4225
    roll angle: 16437
    pitch angle: 780
    yaw angle: 4226
    roll angle: 16438
    pitch angle: 783
    yaw angle: 4228
    roll angle: 16439
    pitch angle: 786
    yaw angle: 4237
    roll angle: 16434
    pitch angle: 792
    yaw angle: 4236

    Hi osmancns, I think you have to divide by a scale factor. I don’t remember what is its value (-91.222 or something like that), but you can find it in the datasheet. Good luck!

  • #1064

    osmancns

    thank you @Saddan hernandez now my problem solved by dividing with 91.02222.
    But now I need to read gyro x,y,z values. How can ı do that with this code (https://github.com/mikehoyer/UM7-Arduino)
    can you help me please ?

      @osmancns

      I’ve made available

      roll_rate, pitch_rate, yaw_rate

      in the binary parser code. Is that what you mean by gyro x,y,z?

      You just have to enable the UM7 to send the gyro rate data over binary for my code read it.

      Let me know how it goes.

      Thanks,
      Mike

    Hello @Mike…
    Okay I will enable gyro sensor data. But I want to see “Raw x gyro , Raw y gyro , Raw z gyro ” values
    with euler angles. What can I do in your code for that.

    I mean that gyro values is here :

      Those variables aren’t available in the binary parser, but you should be able to view them as ASCII output.

    But there is a information about that in um7 datasheet.

    is it not posssible still ?

    Hi Michael,

    I need to get the mag data from the UM7.Could you advice on how to parses binary data packets from the UM7 for getting the processed/raw mag data in order for me to find the heading of the sensor when used with an Arduino.

    Really appreciate your help in advance!!
