Multiple devices on the same I2C pins

[edbyy]

Hi, are multiple devices supported on the same I2C pins? I am having trouble reading data from two devices simultaneously, they work just fine individually. Thanks

Have you confirmed that the addresses of connected IIC devices are independent of each other On 1/10/2021 13:30，blindemu<notifications@github.com> wrote： Hi, are multiple devices supported on the same I2C pins?

Not sure I understand what you mean, the addresses are 0x52 and 0xD2, is there a reason they would interfere with each other?

The device address of the IIC slave should be 7 bits, with the eighth bit for the read/write command On 1/10/2021 13:43，blindemu<notifications@github.com> wrote： Not sure I understand what you mean, the addresses are 0x52 and 0xD2, is there a reason they would interfere with each other? — You are receiving this because you commented.

The devices work when the other is disabled (but pins are still connected) which leads me to believe that the addresses are fine? It's only when I try to communicate with both that I see problems arise.

In my experience, you can not cmmunicate with both, data sending to iic device must be Distinguished with device address On 1/10/2021 13:59，blindemu<notifications@github.com> wrote： The devices work when the other is disabled (but pins are still connected) which leads me to believe that the addresses are fine?
