Hai friends I need to program arm lpc2129 . Can any one help me how to program it using C right from the basic please........
What, exactly, do you mean by that?
- Do you already know the 'C' programming language?
- Do you already know about microcontrollers in general?
Ya i know C programming and also about microcontrollers ,but the thing is I need to know How to program a ARM controller ,mainly about the pinselect options ,how to make a port as genral purpose input output etc..,
Those are not generic questions about any ARM-based microcontroller in general.
Those are specific details about the particular chip - the lpc2129 in your case.
Therefore, to answer those questions, you need to study the manufacturer's documentation for that chip!
Please read the manual!
NXP have a thick document they call the User Manual. It's the main interface for transmission of information about the chip from them to the sw developer. Besides that, they have a data sheet that specializes more on timing, temperatures, voltages that are important for the hw designer.
By now, I would have expected you to have already figured out that NXP somehow must have documented their processor, since they just can't have all developers from all around the world call them for every single little question about the processor. And since there could be zero developers on this forum who would be able to help with anything at all unless we have already been receiving the required information from somewhere else - that somewhere else actually having to be NXP.
Besides their manuals, they also happen to have lots of additional material. Like sample source code and different application notes. But you should already have found them, while looking for the main documentation about the processor. After all, NXP does what most other chip manfucaturers do, and have a web page with relevant links for their different chips.
