Does anyone have any ideas on interfacing the standard 8051 UART in mode 0 to interface to an I2C slave? I was thinking of writing the address of the slave, then shifting the acknowledge back in immediatley after. Any feedback would be appreciated. Matt
'I2C master to communicate and control uart' I think you need to explain exactly what you want to do. As mentioned previously, you don't connect I2C to uart! If you want a uart with an I2C interface, Maxim have a device that does this. You would use this device when you want to add more serial ports to your microcontroller via the I2C . Is this what you want to do? Gong Xi Fat Choi!
