LPC1343 I2C example from LPCOpen, how to use?

Related to the issue I reported few days ago (https://community.nxp.com/thread/494357 ), I'm now trying to run the i2c example code as-it-is

I imported the project in MCUXpresso from the LPCOpen archive for LPC1343, compiled it and flashed it... nothing happends... after launching i see no activity on SCL/SDA pins, I get nothing on the UART output. 

What are the required steps to run this demo?

Hi Dario,

To enable the UART messages you would need to enable first the debug mode.

In the proyect properties -> C/C++ Build-> Settings ->Preprocessor. Add a new define that says :"DEBUG_ENABLE" with this you will enable the UART commands. Do the same in the lpc_board_nxp_lpcxpresso_1347 project.


If you want to see it in a terminal console in your PC, connect an USB to serial in the P0_19 and P0_18. With this you will see the DEBUGSTR in the console.

I hope this can hep you.

Best Regards,

Alexis Andalon
