Hi, I have a CAN module, which transmits the signals either via IC or RS232 (57600 Baud) and i would like to interface this to Sharc processor ADSP-21364 (which doesn't have I2C). Could anyone help, how to interface the two modules. Thanx and Regards, Selvam |

You have to "bit bang" it. Use some flag bits on the 21364 to toggle the I2C lines. The processor is probably 100 times faster than the I2C line (maybe 1000?) so you can use a timer interrupt to flip the bits to the next state. A lot of book keeping detail, but actually really easy to do. Patience, persistence, truth, Dr. mike |

I agree with Dr Mike, the following link will take you to the philips IC page from where you can download the specification. http://www.semiconductors.philips.com/markets/mms/protocols/i2c/ good luck Rainer |
