reading Data using I2C

Micro Club

Hi

i want to read data using I2C, just like reading temperature from any digital sensor, located at the Address 0X00,

Is there a simple source code?

    Why claim "the answer" when it isn't?

    Software delay loops like that, without connection to any hardware and without any defined side effect is not good to use.

    Documentation like:

        //Delay at while before writing to LCD display
    delay(200000ul);


    are not making anyone happy. How long is "at while"? Wouldn't it be much better to have a _real_ delay function and to be able to do: delay_ms(500) and know that you get a delay of 500ms +/- internal rounding/truncation?

    Dummy code like:

    /** Waits until the I2C bus is IDLE, and available to be used. */
#define i2cWaitForIdle()

    is obviously not the answer to any problem.
