I de-soldered the bno055 and have done the following:
1. I can connect my bno055 to an Arduino Uno and run their "rawdata" sketch. This lets me read values:
Code: Select all
X: 0.90 Y: 5.97 Z: -7.59 CALIBRATION: Sys=1 Gyro=3 Accel=3 Mag=3
X: 0.91 Y: 6.02 Z: -2.55 CALIBRATION: Sys=1 Gyro=3 Accel=3 Mag=3
X: 0.90 Y: 6.03 Z: -2.54 CALIBRATION: Sys=1 Gyro=3 Accel=3 Mag=3
X: 0.88 Y: 5.99 Z: -7.58 CALIBRATION: Sys=1 Gyro=3 Accel=3 Mag=3
X: 0.85 Y: 6.01 Z: -7.61 CALIBRATION: Sys=1 Gyro=3 Accel=3 Mag=3
2. I then hook up the same bno055 (using the same wires I used to connect it to UNO) to my ESP32 and I get:
Code: Select all
Ready to download this file,please wait!

download ok
exec(open('./starter, line 46, in __init__
File "bno055.py", line 90, in init
RuntimeError: bad chip id (0 != a0)
>>>
3. I have tried another ESP32 heltec wifi board running the same micropython build (latest from today) and I get the same results.
4. I have a spare bno055 and if I run that on my ESP32, it does show up but I don't get any actual data from is (e.g.
Code: Select all
>>>print(s.temperature())
>>> 0
Thanks in advance for any insight,
