Lpc2000

Hello i want to use crossworks for arm with a lpc2148 board from 
embedded artists.

1) Can I use this compiler for lpc2148 because i found no 
informations on the website. And i also found no sample code for 
lpc2148 on the sample files. 

2) Is difficult to rewrite the sample programs from Phillips (Keil 
bundle or ARM bundle) to Crossworks? What must i look for.

3) Is the tasking libary from rowley the same as an operating system 
like ucos-ii.

4) Is there any port for ucos-ii for rowley crossworks?

5) Is there any sample code for the embedded artist lpc2148 board 
and rowley

thanks alot

Yes.  You can use the compiler for any LPC chip, for any ARM7 for that 
matter.

When creating a new solution I suggest choosing a target chip that has the 
same memory map as the LPC2148 (LPC2138 looks like a good candidate from a 
quick scan of the Philips WEB site, and is an option in CrossWorks), then 
the project should have the startup code and linker setting you need 
automatically.

Slightly different syntax required for:
+ ARM/THUMB interworking,
+ declaration of interrupt service routines
+ intrinsic functions.

Generally it is straight forward.

Have not used it but looks similar: 
http://www.rowley.co.uk/documentation/arm/ctl.htm

Just use a GCC port, it will work with CrossWorks.  I think there is also an 
LPC2148 FreeRTOS.org port in the files section of this group.

Thanks, Today I will start with Crossworks. What do you mean with 
ARM/THUMB interworking ?

Mixing ARM and Thumb code.

Send an email to Rowley tech support and they will send the update for the LPC2148.  Embedded Artists have a lot of examples for their board on their website - once you register.

I think the Embedded Artists USB examples require the use of their
closed source RTOS. Is this true?

EA looks like a hot company and they have a lot of cool new boards. If
they had open source USB code that would add a lot of value to their
offerings.

Eric

@Eric: Sorry I have not used USB till now. So I can't give you any 
information.

Thanks for the information.

Yes, there are a lot of examples on the EA page. But they are coded 
for the GCC and I have some problems concerning that fact.

In the UART Lib as an example they use:

cpsr = disableIRQ();                  // disable global interrupts
U0IER &= ~UIER_ETBEI;                 // disable TX interrupts
restoreIRQ(cpsr);                     // restore global interrupts

but in Crossworks I can´t find the function disableIRQ with returns 
the cpsr and I also can´t find the function restoreIRQ(xxx).

When using the functions from the winarm example-pages with 
crossworks, it doesn´t work.  

How can I port the code for crossworks?

Thanks for your help!

Mathias
