I tried to connect my ESP32 to a sensor GY91(MPU9250 +BMP280). I'm using this library: https://github.com/tuupola/micropython-mpu9250
I used the example code:
import utime
from machine import I2C, Pin
from mpu9250 import MPU9250
i2c = I2C(scl=Pin(22), sda=Pin(21))
sensor = MPU9250(i2c)
print("MPU9250 id: " + hex(sensor.whoami))
while True:
print(sensor.acceleration)
print(sensor.gyro)
print(sensor.magnetic)
print(sensor.temperature)
utime.sleep_ms(1000)
I imported the libraries (mpu6500,mpu9250,ak8963) to my device ESP32. But I have this error when I started the code:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 8, in <module>
File "mpu9250.py", line 45, in __init__
File "mpu6500.py", line 97, in __init__
File "mpu6500.py", line 149, in whoami
File "mpu6500.py", line 181, in _register_char
OSError: [Errno 19] ENODEV
The Sofware I use to program in MicroPython is uPyCraft, I also use Thonny. The Hardware is ESP32 and sensor GY-91 (I connected through 3 cables, Vin(of the sensor) to 5V,SCL to Pin 22 and SDA to Pin 21)
Someone could help me please
