I’m currently working on a rough VR system using the Raspberry Pi 3, and, of course, for that, I need a way to track the custom headset and controllers. I need the sensors to be compatible with Python 3, so that I can track them in 3D space.
Does anyone have any recommendations on any sensors like this?

I have been playing with ADXL345 and found it newbie friendly, comparing to MPU6050: (1) raspberrypi.stackexchange.com/questions/102041/…, (2) (2) raspberrypi.stackexchange.com/questions/105071/… (3) raspberrypi.stackexchange.com/questions/101095/… / to continue, … – tlfong01 48 mins ago

(4) raspberrypi.stackexchange.com/questions/74865/…. BTW. Rpi3B+ cannot change the flat I2C 100kHz rate. This is a problem because smBus cannot do Rpi3B+ cannot change the flat I2C 100kHz rate. This is a problem because smBus cannot do cycle stretching, and must lower I2C speed to 50k or even 10Bd. In other words, you might need to upgrade to Rpi4B to play with MPU6050/9260. That is the reason I follow MagPi 84 Page 45 recommendation on lowering the I2C speed. – tlfong01 38 mins ago

But then I found Bosch BNO055 even better, because there IMU staff is more open than Inversense. So my advice to newbie with a long plan, to try both MPU6050 and ADXL345 and make up your mind later. – tlfong01 38 mins ago

One more reason I prefer ADXL345 over MPU6050 is that ADXL345 is 3-DOF, while MPU6050 is 6-DOF. Actually both have a rather steep learning curve for newbies. I have a ADXL345 working testing program in python and happy to post it here for sharing, in case you are going into ADXL345. And another reason is that you can easily upgrade ADXL345 to industrial grade ADXL355, without changing software. – tlfong01 14 mins ago

More references here: (1) MPU6050 i2cdetect: imgur.com/gallery/6gNrOJe (2) MPU6050 forum posts (with schematic and tutorials): raspberrypi.org/forums/… (3) MPU6050 forum posts: raspberrypi.org/forums/… (4) MPU6050 forum posts:raspberrypi.org/forums/…. Happy sensing and cheers! 🙂 – tlfong01 5 mins ago

I have more mpu6060 posts in other forums, including AAC projects (forum.allaboutcircuits.com/forums/the-projects-forum.6). I need to do searching, in case you wish to have more references at the hardware circuit level. – tlfong01 46 secs ago Edit

I have more mpu6050 (also MPU9250 which is not recommend to those faint of heart newbies) posts in other forums, including AAC (All About Circuits) projects (forum.allaboutcircuits.com/forums/the-projects-forum.6). I need to do some searching, in case you wish to have more references at the hardware circuit level. – tlfong01 4 mins ago Edit Delete
