Hi all,
I want to be able to connect an external analog 0-5V sensor to the NXP Quick-Jack board. I'm looking into using I2C or SPI to connect an external ADC to the Quick Jack board to be able to do this. In the documentation I learned hat the P10 en P11 ports are the SDA and SCL ports for I2C communication. The integrated I2C temperature seems to be allready connected to these ports. If I connect an external I2C ADC to these ports by means of the expension header, do I need to reprogram the chip in order to allow the communication with the external ADC?

Or ar there eassier ways to approach this? All help is appreciated!
