Hello,
I have a selection of sensors I would like to connect with I2C. Most will support 400Khz I2C but 2 are SMBus 100Khz. Reading the datasheet for the K66 it seems the multiple I2C interfaces are really the same bus and is basically multiplexed. Is this correct? Therefore do all ports will need to work at the same speed? I know I need to have the pull-up on each port but not sure about the speed aspects.
I was wondering if I could put my 400Khz sensors on Wire (for example) ad 100Khz on Wire1 and have the different ports running at the top speed of the various sensors. (I believe some of them actually run over 400Khz speed)
Thanks, Jeff
