How to create/where to get all the files for CMSIS/CAPI for a processor

Hi,

I've started work on supporting the NXP LPC1788 processor for mbed...

I've added the module into the targets.py file etc & am trying to source all the files for the CMSIS & CAPI folders...

(I was also trying to effectively re-create the LPC1768 support as a learning process - but the files from the links on the mbed website seem to use older versions of the CMSIS files etc.)

I've downloaded the latest CMSIS package for the LPC1788 from lpcware.com but that doesn't seem to have all the files present (an older version I'd previously downloaded has more of the files)...

I'd appreciate any help that you can offer...

Cheers,

Jez

Hi Jez, there are three sources for a "cmsis" module used by an mbed target.

The ARM CMSIS-CORE module is providing the files that are specific to the Cortex-M cores:

  • core_cmFunc.h
  • core_cmInstr.h
  • cortex_cm0.h / cortex_cm0plus.h / core_cm3.h / cortex_cm4.h

The Silicon Vendor is providing the files for the startup, system initialization, the structures and addressed of the peripherals registers, for a given TARGET:

  • startup_TARGET.s
  • system_TARGET.c
  • system_TARGET.h
  • TARGET.h

mbed is providing additional files to dynamically set the vector table of ISR and to configure the memory model for the given C standard library:

  • cmsis_nvic.c
  • cmsis_nvic.h
  • sys.cpp
  • TARGET.sct
  • cmsis.h

HTH, Emilio
