Hello and first of all please accept my apologies if this is not the place to post this question.

I am using the LPCXpresso 11U68 evaluation module and returning to f/w after multiple years off. I've read the I2C section in the User Manual and gone through the example code. However, what I really need is a step by step approach on configuring and coding the I2C so I can connect a sensor to the 11U68 board. I prefer not to cut and paste but work through this.

Do you know of a resource/URL/App Note? I can not find one.

Thank you.

Hi,

Have you looked at the App note AN11249 ?

http://www.lpcware.com/content/nxpfile/an11249-rom-i2c-driver-usage-lpc11axx

The I2C example code here :

http://www.lpcware.com/content/nxpfile/sample-code-bundle-lpc11xx-peripherals-using-keils-mdk-arm

connects the I2C interface to a temperature sensor on board and communicates to it.

The following document also gives you some information on I2C :
