Could you be a little more specific, define the port as....? What compiler are you using?

For Keil the following may contain:

u mean which language i use??
i use c programming...
As i know, i can define pic directly like PORTA=CAR. Is i define lpc as the same way??

I was actually referring to the C compiler company, Keil, IAR, GCC, etc.


But yes, assigning a port a value would be similar to the procedure used with a PIC.

The actual C compiler and the associated header file would dictate the naming convention for the port.

Does this info help answer your question?

Ehm..... still do not have idea on defining the port in lpc..
Can give me some example???
 

As I indicated before, the #defines, port names, etc are compiler specific.


However here is an example using the Keil C compiler to flash a LED using a timer:

Other examples and appnotes for the LPC2148

Unless you indicate the exact C compiler you are using, this is the best I can do as far as example programs.
