Best Library

Stefano De Blasiis
Note: This was originally posted on 17th March 2010 at http://forums.arm.com

I must begin to develop on a Cortex M3 NXP LPC1758.
I must to implement USB device, I / O, UART, PWM
I would like some impression on the best easiest and least expensive tools to develop.
Moreover what libraries are simpler and Real Time functioning well ?

Keil? LPCXpresso?

Thanks

    Depends on what is the "real-time" requirement you have, maybe mbed is suitable for what you needed.
      (http://mbed.org/)

    It provide libraries, and is very easy for prototyping. That don't have LPC1758 kit, but you can get LPC1768kit or LPC2368 kit and try it out.

    Keil MDK-ARM evaluation version can be downloaded from the Keil web site.
    You can try it out for free, the evaluation version is limited to 32Kbytes but should be sufficient for many applications.

    regards,
    Joseph

    Thank for your link.

    The CMSIS library  have the same structure API for all microcontroller ?
    If I use a NXP Cortex M3 with CMSIS library and after change to Texas-Stellaris Cortex M3 with the CMSIS library the application main don't change ?

    With CMSIS, API for processor features (NVIC, SysTick, processor's control) and CMSIS intrinsic functions are identical.  However, peripheral API are still different. There is plan to try to establish some common API for commonly used peripherals but it is still a long way to go.

    At the moment, in most cases you still need to replace the library call to the peripherals during porting.
    Or you can create you own implementation of the equivalent functions during porting.

    I have read that is possible use μVison 4 with the GNU compiler free.
    There is a guide on how to configure μVision to compile with gnu arm without more code limit?
    The settings should be written in Project -> Manage -> Components, Environment, and Books - Sheet Folder / Extension
    I use LPC1758

    Thanks
