    NUC5I3MYBE I2C clock frequency




      Does anybody know for sure which I2C speed mode is used for the Synopsys DesignWare I2C bus on the custom solution header?

      I'm using Debian Stretch. The bus is working, but I need to connect a device which can only be used in standard mode, so 100kHz.

      Fast mode with 400kHz would be too fast.

      If the NUC uses 400kHz by default, how can I change that in an easy way?

      Tech Spec doesn't say anything about it and even Google didn't help.


      Cheers, Martin
