Hello everyone, I have acquired a very interesting accelerometer module with a compass, is there anyone who has the component created? the model is wit motion, it has i2c and uart, I attach document:

Hi Asmatec

I use a supported IMU the MPU6886.(6 Axis)

mayby it's not what you are looking for but if you tell me what you like to do, I can have a look if it's woorking with this modul

https://shop.m5stack.com/products/6-axi ... nitmpu6886

and is there a big distributor where your WT61P sensor sells?

regards

Stefan

Hello Stefan,

I found the sensor on this page, it has its own communication software, what I really need is something that indicates the inclination and the north, I am developing a solar tracker through the geographic coordinates of the sun.

Hello,
Do you have an example for the MPU6886?
thank you

Hello,
I have done some tests with hmc5883l but in the compass reading it only appears 270 no matter what position I put the sensor in

Hi Asmatec

Check
-if you have pullup resistor for the 2Pin.
-clock and data not reversed
-3.3Volt or 5Volt problem

try if you change channel2 to software

I will get one hmc5883l and try next week


regards

Stefan

Hi Stefan,

The communications are fine, the x and z axes are working but the measure of the compass in degrees sometimes changes the value but it does not correspond to what it should read!

Hi Estefan, have you been able to look at something?

Thank you

Hi asmatec

At the moment I am trying to clarify all possibilities which magnetometers are available and/or which 9 axis sensors are available. For my project I need to use one.
I can use a 6axis sensor and with additional magnetometer
or a 9axis sensor

From Flowcode there are already components
HMC5883L magnetometer
QMC5883L magnetometer
LSM9DS1 9axis

and for these sensors I have already asked Ben to make a component
BMM150 magnetometer
ICM 20948 9axis

regards

Stefan

Hi Stefan,
As I mentioned before, the problem is that the component of the HMC5883L magnetometer doesn't work well, could you verify it?

Regards
