Hello, I am having problem programming LPC1114FN28 MCU. For this, I am using LPCXpresso LPC1769 board, disconected target side. The LPCXpresso shows, that program was downloaded, however - nothing happens, port is still high, when the program was to make it low.

Congratulation, now start your debugger :)

Thanks for the reply. I did start debugger when downloading the program, however nothing happens.

:confused:

Do you know what a debugger is :confused:

So is it running? Stepping? Drinking a beer?

What's it's Perihherals view telling you about your GPIO?

What's it's Perihherals view telling you about your IOCON?

Did you try to switch your GPIO via Peripherals View?

Yeah, I know, however I can't do steps or switch ports using Peripherals View.

The problem was in selecting the clock source, the default was external clock source. Now I am able to debug. Guess it's a good reason to drink a beer for that after all, thanks anyway.
