I2C1 utilization for External sensor interface in OMAP 35x EVM

Other Parts Discussed in Thread: TPS65950

We are using an OMAP 35x EVM in our project.

               We require I2C interface to connect sensor modules to OMAP EVM. We are planning to use I2C1 and I2C3 for connecting 8 sensors. I2C2 is used for connecting wi-fi module. I2C1 from Processor module is routed to ETM connector and Power module(through P10 connector). In power module I2C1 is connected to I2C_cntrl which is described as general purpose I2C used for register read/write of TPS65950. Whether this interface will be held by power module continuously or Could we use this interface for connecting 5 sensors?

  • The I2C protocol is designed to accomodate multiple masters and multiple slaves on the same bus.  There should be no problem with putting multiple devices on the same bus.  Obviously only one transfer can occur at any given time on a given bus.
