multiple i2c devices does not work with mikrosdk 2.0

[luquas]

I'm having i2c problem when using mikrosdk 2.0. When using multiple devices on the bus, only the one started last works. I'm using Necto studio 1.8.2.

Hi Luquas,

I have to ask you to write in English because the purpose of the forum is,
above all, that other users can understand questions and answers.


Kind regards,

Good night,
I'm having i2c problem when using mikrosdk 2.0.
When using multiple devices on the bus, only the one started last works.

Hi Luquas,

Do those I2C devices, which are attached to the same mikroBUS, have the same slave address?


Kind regards,

Good afternoon,
No, it's three devices with different addresses.
After initialization only the last one works.
with two when before calling the read or write function I have to close the ones I'm not going to use and initialize again the one I want to use.
i am using a click temp8 an rtc and i2c driver.

Hi,

With different slave addresses, you should be able to use those clicks simultaneously (one by one, without having to initialize every time).
You can send us some pictures or connection schematics and your project at
support att mikroe dot com
to try to find out the cause.


Kind regards,
Tanja
