    How to implement I2C with ADS ?

    hi there!

    I have some sensors all exporting analog ouputs. To be exaxt i have:

    1 :: 3-axis accellerometer
    3 :: Gyros
    1 :: Compass

    and i want to output their values to I2C. Can you give an implementation either on

    PIC
    AVR
    or
    ARM
    ??

    Thanks in advance

    Re: i2c question

    You can implement I2C if these devices have inbuilt I2c protocol. and how are you giving the analog input to the controllers.
    can you clarify.

    Re: i2c question

    these devices have analog outputs. I need to input their outputs to a ADC and then to a microproccessor (ARM, AVR?). I want info about the circuit and the processor programming.

    Re: i2c question

    If you need to implement I2c with ADC you cannot do it with normal ADC. You need to use serial ADC which supports the I2c protocol. search the web I have forgotten the IC name, it was long back I did it. Then it is very easy for you to implement i2c. You cannot do it with ADC0808/ 0804 or any series.

    If you have that IC then your normal controller can do the i2c implementation
