I want to build a VoIP Phone with STM32F4. Does anybody know, if there is a small SIP-Stack that can easily used with microcontroller.
Thanks Marc

Hi,
I'm having some trouble with the fformat function from the FlashFS library...I think.
I have >50 Qty of a PCBA design, each running the same code. The PCBA has an M3 processor and it interfaces to an SD card using the parallel interface.…
This continues my other post (RXNE/IDLE)... somehow I could not post any longer message (40 words...) in this older post.
After programming EDM1070XX (LPC1857) with ULINK2 I have to power cycle the board to get my code to run. I have tried various options in the Target Driver Setup without success.
My ULINK2 works fine with my LPC2478 boards.
I can control the board…
Dear All
i have a problem with modified version of USB hostlite with Mr Chans FS SFAT32.
DRESULT disk_ioctl(BYTE drv, /* Physical drive number (0..) */
BYTE ctrl, /* Control code */
void *buff /* Buffer to send/receive control data */
)

…Every so often I chase memory overflows (IRAM or variable space) and I never remember where the settings are that need to be changed.
I added a global structure array that caused my code not to even run. When I reduced the size of the new array, the…
Hello,
I'm using the simulator to debug my application. This works fine
except for one thing.
When I modify the code in the simulator and want to rebuild the
application I need to:
- stop simulator
- rebuild application
- start simulator.

Hello,
My code is located in multiple folders. All of these folder have
multiple subfolders.
When I setup my include paths I have to specify all subfolders
separately.
Is there some sort of keyword to tell the compiler to also include all subfolders…
For those who might want to use it - middleware SPI driver for STM32F4xx using DMA transfer is very buggy:
- DMA stream numbers for SPI2 are completely wrong. Instead of streams 3 and 4, it uses streams 2 and 3
Following errors apply both to SPI_SendData…
Not easy to find discussions about uIP. It seems that, developers who use uIP, have very good skills and encounter no problem.
If you are interested in why uip_arp_ipin() has been defined nothing.
#define uip_arp_ipin()
Here is the reason:
Hello,
I often use the "delete trailing white space" function to clean up
my files.
Is it possible to enable this option permanently or is it possible to
create a batch file which cleans up all project .c/.h files?
Hello,
I am still dreaming of a fast way of inline assembly code for fast
addition of 64 bit variables with saturation control. (I need to
write 0x7FFFFFF... to the result register, if overflow occurred).
For this purpose it would be necessary to access…

Hi,
Our company has developed a PCB containing two ARM
controllers.
My question is: is it possible to flash both controllers through one
single JTAG connector or even better flashing both controllers
through one single connector in one go?
Thanks…

Hello,
in the release notes of MDK-ARM Version 4.60 I read that LPC4072
(CortexM4) is supported.
I also read that this MDK-ARM release is delivered with ARM Compiler
v5.0 (5.02.0.28).
Can I use an earlier MDK_ARM to compile/debug code (no peripheral…
All,
I have a project that was compiling and running correctly using an older version of uVision 4. I just upgraded from 4.70a to version 4.71a, and am getting the following error after I compile my project:

I would like to create a C-code module that will contain several
functions.
It should be R/W and R/O independent and at the beginning it should
contain
a table which will hold offsets of the contained functions relative
to the

We tinker with the idea of using RL ARM in the future. I found the very interesting document "Getting Started Building Applications with RL-ARM". This pdf is a very detailed description of realtime library and the rtos itself.

Hi,
I'm using the STM32F103ZD microcontroller. This uC is residing on some control board and is physically connected by it's address bus and data bus to an external 1M*16 SRAM memory chip.

Dear all,
The recently started working with ARM Cortex-M3 with MCB1700
