    • CORE 2 and how to chain 2x paHUB2

      Dear, I using for my project a Core 2 controller and I need to have more than 6 I2C ports. I am developing under the graphical interface UIFLOW.

      In this contexte, I bought 2x pa.HUB2 units (I2C Hub 1 to 6 Expansion Unit).

      I changed the default I2C address of the second paHUB2 unit (from 0x70 to 0x71). Then I plugged this device to the channel 5 of the first pa.HUB2 unit.

      To test, i made a very simple program based on 2 sensors, a TOF sensors connected to the channel 0 of the first pa.HUB2. This first pa.HUB2 is connected to the port A of the CORE 2 controller.

      and a second sensor, ENV III sensors who is connected to the second pa.HUB2 unit, channel 0.

      When I run my simple program (based only on a loop to refresh 2 labels to get ENV III temperature and TOF distance), I got a BUS error.

      I am stuck on this, what I am doing wrong ?

      Thanks for your help
