MC9S08JM32 & I2C? Hardware question...

Hi all,

 

I´m trying to implement the 12bit DAC MCP4725A0T-E/CH on the MC9S08JM32 uC.

I´ve never worked with I2c and I don´t know how to connect it to the uC and what ports should I use.

I see that the uC have 2 SPI interfaces and one port for serial communications which I actually use for the USB trough an FT232 USB/serial converter.

 

Can I connect SPI interfaces to the I2C pins of the DAC? what chances I have?

 

Hope someone bring a little of light in this question, I have been reading something about SPI and I2C but I fear they are not the same at hardware level... so maybe is not possible?

 

Thanks in advance.

 

Cristian.
