Yes this works! That's wonderful! Pitch and roll are my my gain goal, but I will probably also have a magnetometer on the board, so I can try to feed that data into the Reefwing AHRS as well. I'm guessing just the raw xyz values from the magnetometer and replace current DOF setting with this...

This is a bit beyond my limits I'm afraid. Perhaps time to find some one a bit more skillfull than myself to tie this one together. I was just wondering. Was my observation about the Mahony and Medgwick filters not being well suited for tracking more rapid movements correct? And if so, is it...

The error came from line 76; ahrs.setData(data);

I got the Madgwick and Mahony filters running icw Brian's MPU6500 library (added both files in case a future user might find them helpful). But the roll, pitch and heading are very slow responsive. I guess these algorithms are best suited for low dynamic situations? I decided to give the...

Thank you so much for your help!

Will do. The sensor is working with @brtaylor's library. The linking is a bit of a challenge for me, but will dive into the matter tomorrow. Thanks!

This method sounds great to me as well. Juist need to get my head around how to change the code along these lines; feeding imu data from the invensense library into the mahonyahrs library. Bottomline; I'm not much of a programmer... You don't happen to have an example code laying around I could...

Just noticed that the library you suggested is for the MPU6050. Perhaps it won't work for the 6500...?

I started off with an example from the Reefwing6500 library. The example code you posted in earlier post gave me this error; Compilation error: 'MPU6500' does not name a type I connected the IMU and using library underneath I've managed to make a connection...

Sorry for the slow response... unfortunately I haven't been able to connect to the MPU6500 using the Reefwing MPU6500 library. Just for the basic connection check I'm using this code; #include <ReefwingMPU6050.h> ReefwingMPU6050 imu; void setup() { imu.begin(MPU6050_SCALE_2000DPS...

Yes this compiles. Thank you so much! Now the next step... The example connects using SPI. I was hoping to connect using I2C. According to the library documentation this should be possible, but I can't find any examples that show how...

Hi there, I'm looking for a library that can calculate roll, pitch, yaw and heading angles using the MPU6500 IMU and that is compatible with Teensy 4.1. I found the Reefwing AHRS library. There's an example patch for the MPU6500 and MKR boards (file attached). I'm not able to compile that...

Was thinking in the same line. But perhaps my circuit running 4 I2C sensors and writing to SD card every 100ms is already enough consumption.

Ah I hadn't thought of that. Will do some testing in that regard. If I do any interesting/substantial finds I will surely post them here.

Thanks! I'm running 4 I2C sensors (gyro, 2 magnetometers and a clock), so 150mA should be plenty. So then 3.3 is the preferred way to go, right? (sorry I failed to mention Teensy (4.1) version - I've corrected it above)

Hi there, I had a hardware question. I aim to build a small data collector to take with me on a biking trip. I want to use a powerbank as the power source. Simplest would be to just power the Teensy 4.1 using a powerbank (5v) and then powering the sensors in the circuit using the 3v output on...

Ooooh yes. How could I have overlooked that one. Thank you!!!!

Still getting this error though; Compilation error: expected ')' before ';' token So I'm guessing something is wrong with my syntax...? The attached code is not the full code. Just what's relevant for this issue. But put a closing line in there now. #include <SD.h> #include <I2C_RTC.h>...

Ok but I need to get the date information from my I2C clock while running my code in the field. So somehow 'year()' needs to point to - be replaced by - RTC.getYear() I think

I thought I did understand. Or not really (sprintf/C is somewhat of a mystery to me), but at least I thought my small adaptation of your code was correct. But apparently I'm doing something wrong. Sorry. Also understand you're not going to literally write my code.

Sorry. Changed the code in the previous post. Compilation error: expected ')' before ';' token

Ok great! Thank you so much. I was considering to write (possibly multiple session per day) in the same file each day. It's more of a safety measure than that I need a very strict separation of data. But great to have the code at hand if I change my mind. I. I applied your code a bit, but...

Hi there. I'm stuck trying to figure out how to generate a different filename every day. I came across this topic: https://forum.pjrc.com/index.php?threads/sd-card-filename-struggles.60084/ But I'm not sure how to apply that to my aim. I guess I need to work with char instead of strings...

Followed instructions in topic underneath and now have two compass sensors running simultaneously on two I2C busses on a Teensy 4.1 https://forum.arduino.cc/t/how-to-use-i2c-sda2-and-scl2-on-stm32f103c8tb-with-my-compass-hmc5883l/1001527/8

Hi there. I'm trying to use two I2C sensors (HW-246 GY-271) simultaneously. From what I've read it should be possible to have the two sensors connected to the same pins on the Arduino. I also have a Teensy, which has multiple I2C pins. But the libraries (QMC5883L) I'm using don't have any method...
