Hi Ben

The MPU6886 is working nice with the adress 0(0x68)

But NOT with the adress 0(0x69) (and hardware change pin A0)

Stefan

Hi Ben

So if I use only one IMU, that's ok

Adress 0(0x69) with A0 GND works
Adress1(0x69) with A0 3v3 works

unfortunately I need both IMU

There is already a problem with initialising

This program does not run, it hangs on the second test.
no matter if address 0 or 1 first

Stefan

hang on second test:

Hi Ben

I prepared 4 IMU
2pcs with adress 0x68
2pcs with adress 0x69

I tested individually on bus1 and all of these work well.

So I connected them all on bus1 and bus2 and this is not working
but if I connect one module to bus1 and the other to bus2, it works no matter which address I use.
Only one module works on one bus!
(of course I have always adjusted the addresses and pins)

My hardware has 2 groove connector, but soon I have to connect it to a smaller hardware with only one i2c bus free

Hi Stefan,

Is it an ESP you're using? I think I might need to make a similar mod like I did to the ESP32 SPI CAL.

Hi Ben

Yes it's an ESP32 now and later.

OK thanks, I'll look into doing the mod for you this afternoon.

Hello,

Right I've pushed a change and checked it compiles ok. Hopefully this should now allow multiple components to share the same ESP32 I2C hardware channel.

Let me know how you get on.

Hi Ben

I tested two modul on the same bus and now it's working perfect!

thank's alot

regards

Stefan
