LPC2138 and FreeRTOS

Started by Peter Homann August 24, 2005
Hi,

I'm looking at using FreeRTOS on a LPC2138 based project. Does anyone
have any opinions, tips or experiences they could share on how
successful this combination is.

Thanks in advance.

Cheers,

Peter.

An Engineer's Guide to the LPC2100 Series

I did an early port of this to the IAR tool chain. It took a while to
get my mind around all the files, but, in truth, it is quite small and
easy to work with. The documentation is only available online. I would
prefer a PDF to a web page, but that is a nit.
I am using FreeRTOS on several projects. I like the following features:
- Lean (small footprint, only the features I need.)

- Evolving (almost too many code drops. I am giving up on
chasing changes)

- Tractable. I got my mind around the entire code base, because
it is so small
In the past, deeply embedded projects often would not use any RTOS. This
brings true tasking to my systems without the overhead and cost of WinCE
or Linux. I considered uCOS, but this package does all that I need from
uCOS. And the price is right.

Hi Dan,

That was the answer I was looking for. I initially wanted to use
UCOS-ii, but can't justify the licence cost at this stage.

Thanks,

Peter.

Hi Dan,

Did you find the port from gcc to IAR difficult? I am using IAR and
I was looking at the LPC2106 gcc version and porting that to the IAR 2106.

Thanks,
Charles

I have used FreeRTOS with GCC on a LPC2106 (for testing & design) and
on a LPC2138. It worked "out of the box" (except that I first fell
into the trap of using another "boot.s" file than the one that came
with FreeRTOS). I made a few modifications, for improved memory and
task tracing, and these modifications were easy to make due to the
clear lay-out of the code.

The code is documented with Doxygen. This implies that the
documentation resides in comments mixed in the source code (very
convenient if you want to customize the code, or understand how it
works). In addition, if you get Doxygen, you can extract new
documentation yourself (e.g. in RTF format, to print it with Microsoft
Word or OpenOffice).

All in all, there is much to like in FreeRTOS.

I have just posted FreeRTOS Version 3.20 for IAR/ARM on my website
ftp://inclinesoftworks.com <ftp://inclinesoftworks.com/> Use UserName
incline9_cust and pw freertos.
This version of FreeRTOS has been adapted to IAR/ARM. (Using Version
4.30a of WARM). It works with MCB2100 Eval Board. It is adapted from
the Keil and SAM versions of the RTOS.
If you have questions, you can contact me..

Hi Dan,

I downloaded the port and tried to make it. Came up with the following
error. :-) The file does not exist?

Fatal Error[Pe005]: could not open source file
"C:\FreeRTOS_3.20\Source\portable\MemMang\heap_1.c" Cheers,

Peter.

Thanks. I tried to strip the release down to the minimal size... I
missed a couple files. I did another test and the build is successful
on my machine.

Dan,

I tried to download it from your ftp site but it didn't let me in. I tried again but still not able to login.

Dan,

I tried to download it from your ftp site but it didn't let me in. I tried again but still not able to login.

I have just posted FreeRTOS Version 3.20 for IAR/ARM on my website
ftp://inclinesoftworks.com <ftp://inclinesoftworks.com/> Use UserName
incline9_cust and pw freertos.
This version of FreeRTOS has been adapted to IAR/ARM. (Using Version
4.30a of WARM). It works with MCB2100 Eval Board. It is adapted from
the Keil and SAM versions of the RTOS.
If you have questions, you can contact me..

Did you find the port from gcc to IAR difficult? I am using IAR and
I was looking at the LPC2106 gcc version and porting that to the IAR
2106.

Thanks,
Charles
