System analysis tool: plant response with/without encoders enabled
Hi AlexMos, I know you are a busy guy and my original questions may have been a bit too probing, but wanted to follow-up and see if there is any feedback you can give. I'm interested in learning more about what control scheme you use when the…

2 motors, same axis, different rpm

IMU Sensor Connections
You don't HAVE to add a second IMU, it just gives you more precise stabilization. Regardless, if you are connecting multiple sensors to the same I2C (or CAN) bus these sensors share the different lines (5V, GND, SCL, SDA for I2C) so I guess yo…

Non-liearities correction calibration does not work
Hello Alex, Thank you for your response! Admittedly, when I first set up my system I just skimmed through the "Using encoders with SimpleBGC 32 controllers" document -- so I did not realize that the EL Field Calibration and Offset MUST be…
