Software I2C in slave mode

Archie Zhang

I want to simulate an I2C slave device using a generic 8051 MPU which doesn't have hardware I2C(not like 80C552). I know it is easy to implement software simulated I2C in master mode, but I want to turn my 8051 MPU to be a slave device. How can?

    I am not entirely rigid with the chip. However I have access to two bipom board with atmel 89S53.
    You can replace the 89S53 with a pin compatible P89C66x. The P89C66x is ISP via the serial port, so if the board has a RS232 connection, you will have ISP.
