    connecting multiple sensors on I2C

    fa235_1780096

      Hello everyone: I am working on a project in which I want to use two accelerometers on a PSOC4 BLE. I worked with an example where an I2C is connected a single accelerometer. I want to add another accelerometer. Could anyone point to me a PSOC example that could help me understand how to connect multiple sensors on an I2C. I read about I2C bus and about master/slave concept, but did not understand a lot.

         

      It would be great if you could also answer following question:

         

      1. when should I use master I2C and when a slave I2C?

         

      2. is it possible to have two I2C each with one accelerometer connected to four pins on PSOC? right now I have one I2C with SCL going in pin 3[5] and SDA going in pin 3[4].

         

      Thanks you in advance:
