Documentation for NXP C Library Methods?

I've searched high and low, but apparently missed something on the NXP site. For the CodeRed/LPCxpresso LPC111x family, where is the documentation of NXP libraries? For example, GPIOInit(), I2CInit(), etc.? Sorry for the rather (to some) obvious question, but nowhere in the example, CodeRead compiler install, etc. can I seem to find a PDF file with documentation.

Thanks in advance

Dave

Hello,

The source code is usually commented:

Quote:
Function name:        GPIOSetDir

Descriptions:        Set the direction in GPIO port

parameters:            port num, bit position, direction (1 out, 0 input)
Returned value:        None

But certainly, the documentation (and examples) is very poor when compared with other microcontrollers, such as AVR, 8051, Propeller, etc.

Indeed as observered through the example code. Clearly one can hover the mouse over a function call in sample code. What I am seeking is documentation on the library to get a 10,000ft view of what functions are available. Again, I can open all the include files and do this the hard way but doesn' it seem reasonable to you to have the library functions documented - the equivalent of the "Stellaris Family Driver Library User's Guide" perhaps called "LPCxpresso Driver Library User's Guide"???

LPC1700's DriverLibrary includes a CHM file. It's not great (auto-generated from Doxygen comments), but does help.

Thanks. I'll take a look. There is a file included with the LPC11xx version called "lpc17xx.cmsis.driver.library.zip" that is similar, and it too is rather limited. There is a table on the NXP site:

http://ics.nxp.com/literature/other/microcontrollers/pdf/arm.mcu.free.nxp.software.pdf

that has all but the Cortex-M0 parts. My guess is that this family is so new NXP doesn't have such a document completed just yet; that and the fact that CMSIS seems to be the way of the ARM library future and the common library used now if being updated/replaced by CMSIS compliant libraries. So, perhaps later. The product is looking promising so I hope this is temporary.

I believe I have it now. Perhaps someone can comment on my conclusion. Apparently, the provided example software is based on CMSIS 1p30; at present the only the core due to ARM removing the middleware until all CMSIS participants can agree on the standard. The remaining (non-core specific) example code was developed independantly or used CMSIS 1P20 or earlier...hence documentation is iffy until CMSIS middleware is complete. Just trying to get a handle on how to apprach NXP development strategy.
