Hi, I will be starting a new project using the LPC2114 and I have to decide on an IDE to do the development. I have been considering the Rowley Crossworks and IAR Embedded Workbench. I know they are very different in price ($800 vs $3000), but when doing professional work the price difference is less important than the quality of the tools. Is the quality of the code from the proprietary compiler of IAR significantly better that the GCC compiler of Crossworks. Do either of these products have an advantage in terms of features or stability or support. Does anyone have an experience that would help me make the right choice. Is there another IDE that I should consider. I know the IAR and Rowley read this group, so if you would prefer, you can email me directly. Thanks for your help. As I become more knowledgeable about the LPC2xxx, I hope to return the favor. Bob Davis |

Just out of curiosity, why do you feel compelled to use an IDE? --jc rkd0930home wrote: > Hi, > > I will be starting a new project using the LPC2114 and I have to > decide on an IDE to do the development.

Hello, We have the same problem at the moment. We consider the Hitech system (www.hitech.com.au) - or a chinese system with the GNU compiler and a JTAG debugger (www.embedinfo.com). Anybody has experience with these? Somebody asked why one would need an integrated development system. Answer: just for the debugger - not for the compiler and linker, since "make" is a tool with much more options than any IDE I saw up to now. Regards Thomas Leuthner |

I have downloaded the compiler and read some of the manual and sent them som questions ! Here they are I have downloaded the ARM Evaluation C compiler. 1)Is is possible to use JTAG debug with the compiler together with ex. Philips LPC2104 ? 2)I can not find anything about JTAG in the USER Manual ?? 3)Is the compiler based on GNU or is it your own work ? The answers from HItech 1) I am not 100% about the JTAG for Philips LPC2104. Hi-Tide uses Seehau ARM debugger to debug the chips. I believe they do, but you might want to contact them directly to confirm. 2) The manual does not mention debugger for the reason that it is a third party tool. You should be able to find some info on it in "getting started" guide. 3) The compiler is our own work. You should find it fairly easy to use if you have worked with gcc in the past, as both of them are ANSI C compliant and quite a few compiler options in our compilers mirror those found in gcc. -------------------------------- I am self considering compiler and IDE. I think I will go for IAR or Rowley Best regards John Noergaard |

I am not compelled to use an IDE. When I write code I like to step through it to insure that it does what I intended. I find an IDE to be a convenient way to do this. If I find a mistake, and I do make mistakes, I edit the source, compile, link, load and continue stepping. This way I very rarely have bugs in released code. Every one has their own way of working. This works for me. Now back to my question. Do you have any suggestions about IDEs for the LPC2114? |

Hi, take a look at the Keil IDE, the ARM support eval is for free (full GNU compiler, 16K limited debugger). Its the best and most integrated IDE, while still giving you the options to set command line arguments. So far, their simulator is the best I have seen. One button does it all. Very stable too. |

Hi
Bob,
Have you
considered Ashling?. We offer a complete range of development tools
including:
LPC2xxx Evaluation Board with on-board JTAG emulator
•Integrated Development Environment and Compiler (GNU based)
•Source-level Debugger
•Stand-alone USB based JTAG Emulator
•Stand-alone USB/Ethernet based JTAG Emulator
with Real Time Trace
support
Where
are you based ? Let me know and I can get our local office to contact you. Feel
free to send me any questions. For more details on our tools see our dedicated
LPC2000 page (includes FAQ) at the link below:

Hi Bob, It's worth asking the question: Does the IDE support integrated Flash download and debug? This means that from an IDE you can set breakpoints in the editor, press a button and the IDE will program the flash, set the breakpoints (both of them :-<) and start the processor executing etc etc. CrossWorks for ARM can do this using either the Primary or the Secondary JTAG pins of the LPC2000 family and can program the flash at 16Kbytes per second using a standard wiggler or equivalent (our favourite is the OLIMEX JTAG ARM).

Hi, there have been many ports to support the LPC2000 family already. Ashling, Hitech, IAR, Keil, Rowley just to name some of them (in alphabetical order). Also the ARM RealView and GHS support the family. In my personal opinion, the most important consideration is what you used so far rather than the difference in features. If you are a migrating 51-customer and you used IAR or Keil and you were satisfied, the logical choice is to stay with them. Same is true if you are migrating from PIC and used Hitech or from MSP430 / AVR and used IAR, stay with them if you like the IDE. Another consideration is what kind of debugger / emulator you want to use. If Ashling is your first choice, you might also want to use their compiler port (single source supply). If Nohau is your favorite, they work closely with Hitech and IAR. If Hitex is your favorite, the closest partner is Keil. If you use a standard wiggler, Rowley seems to work very reliably. The long story short, there are too many combinations to recommend an IDE that suits everyone. Some statements have already been made: Rowley works nicely with Olimex tools Keil has the best simulator (helpful for more than 1 breakpoint in flash memory) In general dedicated compiler such as GHS, ARM, IAR and the new kid on the block Hitech have a little better code-density than a GNU-based compiler. Whether that is important for you, you decide. Summary: there are a lot of mature tools on the market and you might want to get an evaluation version, compile some code and compare the results based on your own code. You will also see the difference in look and feel between the tools you will evaluate. A lot of the like / dislike is personal taste. Hope I did not offend any of our tool partners while still providing some useful information ;-) Regards, Robert |

I would consider using keil uVision in cooperation with ADS(arm develper studio) compiler/linker. /Pero --- Monday, March 15, 2004, 6:20:22 PM, si napisal: > Hi, > there have been many ports to support the LPC2000 family already. > Ashling, Hitech, IAR, Keil, Rowley just to name some of them (in > alphabetical order).
