IMU sensor - dariosplit - 2022-12-23 Hello everyone, I'm trying to make my first openploter pypilot project and I have RPi 4, MPU 92/65 which is actually MPU6500 and compass GY-271. My system detects it as: Using settings file RTIMULib.ini Settings file not found. Using defaults and creating settings file Detected HMC5883L at standard address Using fusion algorithm Kalman STATE4 IMU Name: L3G4200D + HMC5883L min/max compass calibration not in Detected HMC5883L at standard address IMU Name: L3G4200D + HMC5883L min/max compass calibration not in use Using ellipsoid compass calibration Using accel calibration nmea server on port 20220: bind failed. imu process failed to keep time 0.10734327800000187 54.926412966 55.033620466 55 .033697003 55.033754114 I2C read error from 105, 39 - Failed to read L3G4200D status failed to read IMU! 55.033873244 servo probe ('/dev/ttyAMA0', 38400) 55.159951114 failed to open servo on: ('/dev/ttyAMA0', Is there any hope that this will work or do I have to order another sensor. Any help is welcome RE: IMU sensor - seandepagnier - 2022-12-23 what do you see from i2c-detect? It seems pypilot services are already running (bind failed) etc could you stop them first with: sudo service pypilot stop I am not sure if it is detecting the device wrong?

Can arduino uno serve as a motor controller. RE: IMU sensor - dariosplit - 2022-12-24 Hello, ordered from pypilot shop and gave up trying to use GY-271 with fake MPU9250. Happy Holidays. |
