AXI IIC Bus Interface question

Jump to solution

Hello,

I want to use the AXI IIC bus Interface found in Vivado to read data from several MLX90393 sensors. My question is about the amount of AXI IIC interfaces needed for this. Is it enough to use only one, or is it necessary to use one for each sensor that will be used? Thanks in advance.

If your Sensors are configured to different addresses, you can share a bus for them. A quick glance at your datasheet tells me that you can have up to 4 sensors on one I2C bus, if you hook up the proper pullup/downs for address configuration.

 

Also make sure to include the proper Pullups on the I2C bus.
