Hi, can possible read value from ADC2 pins (for gpio 2)?

im added in machine_adc.c
and compile.

But it is probably not enough?
Thanks.

Hi, can possible read value from ADC2 pins ?

Thanks.

UPDATE: my mistake i meant esp32 sorry.

I mean to send/save the offsets. In order not to calibrate every time it is turned on.

Thanks for reply. I am using esp32. It also tests with the wires. As for them, I agree, IMU is awesome. But I'm having trouble calibrating after rebooting. I have mag offsets saved, after restart I send them to the device, but I don't know acc and gyro offsets so I don't give them, sometimes it's fi...

I think adding a timeout in i2c to 2000 helped, but is that a good solution and will it always work?

Hi, im use this driver: https://github.com/micropython-IMU/micropython-bno055/blob/master/bno055_base.py imu: https://www.dfrobot.com/product-1793.html It's ok, it's getting the data, but sometimes I get an error: File "libs/bno055_base.py", line 115, in _readn OSError: [Errno 110] ETIMEDOUT i2c: i2...

Thanks for reply.

Then it only sees the accelerometer data - the magnetometer does not.

Hi, im connect to esp32 lsm303d sensor.

Using this driver:
https://github.com/kamikaze/pyboard-exa ... /lsm303.py

in i2c scan: He only sees the accelerometer, why can't he see the magnetometer as well?

Hi, im trying use this driver to connect lsm303d: https://github.com/kamikaze/pyboard-examples/blob/master/imu/lsm303.py im have error: Traceback (most recent call last): File "<stdin>", line 68, in <module> File "<stdin>", line 31, in __init__ OSError: [Errno 19] ENODEV i2c scan: >>> i2c.scan() [29]
