[SOLVED] IMU address conflict - svtgd - 2019-02-09 Today the data from my MPU9250 disappeared. Took a look and see that in I2C tab, IMU-92xx no longer exists and perhaps has been replaced with MS-560702BA03. It has address 0x77 - which is same address assigned to my BMP180. Pypilot tab shows IMUs detected:0 - but still has checkboxes selected for imu.heading and pitch, roll. How to fix? RE: IMU address conflict - jim321 - 2019-02-09 what does this command show sudo i2cdetect -y 1 was it working before and what have you done to it lately .? i know bmp-280 works i have never tried the bmp-180. it is setup to use bmE-280 that has a humidity sensor . the mpu should be 0x68 or 0x69 this is how mine looks with mpu-9255 and bmp280. pi@openplotter:~ $ sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 40: 40 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- -- 70: 70 -- -- -- -- -- 76 -- RE: IMU address conflict - svtgd - 2019-02-09 my bad - i had managed to switch wires to scl/sda... fixed that and MPU9250 now recognized at 0x68 - all good now. Sorry for the false alarm and thanks for the help jim321. |
