Keil C "library" and documentation?

James Corbin

I'm just now evaluating the latest Keil c51 tool. In the past, I've used c compilers for other embedded platforms. Many of these other platforms not only provided a good compiler, but provided great code "examples" and libraries. For instance, a already coded character LCD "library".

So far with the evaluation of Keil, I've noticed rather minimal library support. And the examples that I looked at didn't look like they would be very helpful to me. I've got a couple questions:

1) Does a purchased version contain additional libraries that the evaluation version does not? Any extra stuff that would speed up the process of coding basic interface libraries common to most embedded systems (i2c, lcd, keypad, etc)?


2) How is the documentation on the compiler\tools? Thorough and easy to get up to speed on?

Thanks

    There are a number of examples on this web site at: http://www.keil.com/download/c51.asp.

    As far as libraries, there are none provided for hardware interfaced peripherals. Over 500 8051 devices are supported (some of them include LCD controllers). When you consider how many LCD controllers there are and the number of 8051 devices and the number of ways you could possibly interface the LCD, the likelyhood of a generic LCD library becomes nearly impossible.

    Nonetheless, there are plenty of places to find LCD routines on the web. I'd probably start with http://www.8052.com.

    For documentation, printed manuals are included and HTML manuals are available on the web site, the support knowledgebase actually answers about 90% of all technical support questions (for those who can read :-), and this discussion forum solves a lot of problems and is a good place to get feedback about ideas and locate other sources of information.

    But, of course, I'm biased. Maybe someone else would like to take a crack at answering your questions.
